17
18 Single precision divide for signed binary integers.
19
20 The quotient is truncated towards zero.
21 The sign of the quotient is the XOR of the signs of the dividend and
22 divisor.
23 Divide by zero is trapped.
24 Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.
25
26 INPUT REGISTERS:
27 . arg0 == dividend
28 . arg1 == divisor
29 . mrp == return pc
30 . sr0 == return space when called externally
31
32 OUTPUT REGISTERS:
33 . arg0 = undefined
34 . arg1 = undefined
35 . ret1 = quotient
36
37 OTHER REGISTERS AFFECTED:
38 . r1 = undefined
39
40 SIDE EFFECTS:
41 . Causes a trap under the following conditions:
42 . divisor is zero (traps with ADDIT,= 0,25,0)
43 . dividend==-2**31 and divisor==-1 and routine is $$divoI
44 . (traps with ADDO 26,25,0)
45 . Changes memory at the following places:
46 . NONE
47
48 PERMISSIBLE CONTEXT:
49 . Unwindable.
50 . Suitable for internal or external millicode.
51 . Assumes the special millicode register conventions.
52
53 DISCUSSION:
54 . Branchs to other millicode routines using BE
55 . $$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
56 .
57 . For selected divisors, calls a divide by constant routine written by
58 . Karl Pettis. Eligible divisors are 1..15 excluding 11 and 13.
59 .
60 . The only overflow case is -2**31 divided by -1.
61 . Both routines return -2**31 but only $$divoI traps. */

63/* TRUNCATED DIVISION BY SMALL INTEGERS
64
65 We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
66 (with y fixed).
67
68 Let a = floor(z/y), for some choice of z. Note that z will be
69 chosen so that division by z is cheap.
70
71 Let r be the remainder(z/y). In other words, r = z - ay.
72
73 Now, our method is to choose a value for b such that
74
75 q'(x) = floor((ax+b)/z)
76
77 is equal to q(x) over as large a range of x as possible. If the
78 two are equal over a sufficiently large range, and if it is easy to
79 form the product (ax), and it is easy to divide by z, then we can
80 perform the division much faster than the general division algorithm.
81
82 So, we want the following to be true:
83
84 . For x in the following range:
85 .
86 . ky <= x < (k+1)y
87 .
88 . implies that
89 .
90 . k <= (ax+b)/z < (k+1)
91
92 We want to determine b such that this is true for all k in the
93 range {0..K} for some maximum K.
94
95 Since (ax+b) is an increasing function of x, we can take each
96 bound separately to determine the "best" value for b.
97
98 (ax+b)/z < (k+1) implies
99
100 (a((k+1)y-1)+b < (k+1)z implies
101
102 b < a + (k+1)(z-ay) implies
103
104 b < a + (k+1)r
105
106 This needs to be true for all k in the range {0..K}. In
107 particular, it is true for k = 0 and this leads to a maximum
108 acceptable value for b.
109
110 b < a+r or b <= a+r-1
111
112 Taking the other bound, we have
113
114 k <= (ax+b)/z implies
115
116 k <= (aky+b)/z implies
117
118 k(z-ay) <= b implies
119
120 kr <= b
121
122 Clearly, the largest range for k will be achieved by maximizing b,
123 when r is not zero. When r is zero, then the simplest choice for b
124 is 0. When r is not 0, set
125
126 . b = a+r-1
127
128 Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
129 for all x in the range:
130
131 . 0 <= x < (K+1)y
132
133 We need to determine what K is. Of our two bounds,
134
135 . b < a+(k+1)r is satisfied for all k >= 0, by construction.
136
137 The other bound is
138
139 . kr <= b
140
141 This is always true if r = 0. If r is not 0 (the usual case), then
142 K = floor((a+r-1)/r), is the maximum value for k.
143
144 Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
145 answer for q(x) = floor(x/y) when x is in the range
146
147 (0,(K+1)y-1) K = floor((a+r-1)/r)
148
149 To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
150 the formula for q'(x) yields the correct value of q(x) for all x
151 representable by a single word in HPPA.
152
153 We are also constrained in that computing the product (ax), adding
154 b, and dividing by z must all be done quickly, otherwise we will be
155 better off going through the general algorithm using the DS
156 instruction, which uses approximately 70 cycles.
157
158 For each y, there is a choice of z which satisfies the constraints
159 for (K+1)y >= 2**32. We may not, however, be able to satisfy the
160 timing constraints for arbitrary y. It seems that z being equal to
161 a power of 2 or a power of 2 minus 1 is as good as we can do, since
162 it minimizes the time to do division by z. We want the choice of z
163 to also result in a value for (a) that minimizes the computation of
164 the product (ax). This is best achieved if (a) has a regular bit
165 pattern (so the multiplication can be done with shifts and adds).
166 The value of (a) also needs to be less than 2**32 so the product is
167 always guaranteed to fit in 2 words.
168
169 In actual practice, the following should be done:
170
171 1) For negative x, you should take the absolute value and remember
172 . the fact so that the result can be negated. This obviously does
173 . not apply in the unsigned case.
174 2) For even y, you should factor out the power of 2 that divides y
175 . and divide x by it. You can then proceed by dividing by the
176 . odd factor of y.
177
178 Here is a table of some odd values of y, and corresponding choices
179 for z which are "good".
180
181 y z r a (hex) max x (hex)
182
183 3 2**32 1 55555555 100000001
184 5 2**32 1 33333333 100000003
185 7 2**24-1 0 249249 (infinite)
186 9 2**24-1 0 1c71c7 (infinite)
187 11 2**20-1 0 1745d (infinite)
188 13 2**24-1 0 13b13b (infinite)
189 15 2**32 1 11111111 10000000d
190 17 2**32 1 f0f0f0f 10000000f
191
192 If r is 1, then b = a+r-1 = a. This simplifies the computation
193 of (ax+b), since you can compute (x+1)(a) instead. If r is 0,
194 then b = 0 is ok to use which simplifies (ax+b).
195
196 The bit patterns for 55555555, 33333333, and 11111111 are obviously
197 very regular. The bit patterns for the other values of a above are:
198
199 y (hex) (binary)
200
201 7 249249 001001001001001001001001 << regular >>
202 9 1c71c7 000111000111000111000111 << regular >>
203 11 1745d 000000010111010001011101 << irregular >>
204 13 13b13b 000100111011000100111011 << irregular >>
205
206 The bit patterns for (a) corresponding to (y) of 11 and 13 may be
207 too irregular to warrant using this method.
208
209 When z is a power of 2 minus 1, then the division by z is slightly
210 more complicated, involving an iterative solution.
211
212 The code presented here solves division by 1 through 17, except for
213 11 and 13. There are algorithms for both signed and unsigned
214 quantities given.

232
233 Now, the algorithm for 7, 9, and 14 is an iterative one. That is,
234 a loop body is executed until the tentative quotient is 0. The
235 number of times the loop body is executed varies depending on the
236 dividend, but is never more than two times. If the dividend is
237 less than the divisor, then the loop body is not executed at all.
238 Each iteration adds 4 cycles to the timings.

539 z = 2**24-1
540 r = z mod x = 0
541
542 so choose b = 0
543
544 Also, in order to divide by z = 2**24-1, we approximate by dividing
545 by (z+1) = 2**24 (which is easy), and then correcting.
546
547 (ax) = (z+1)q' + r
548 . = zq' + (q'+r)
549
550 So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
551 Then the true remainder of (ax)/z is (q'+r). Repeat the process
552 with this new remainder, adding the tentative quotients together,
553 until a tentative quotient is 0 (and then we are done). There is
554 one last correction to be done. It is possible that (q'+r) = z.
555 If so, then (q'+r)/(z+1) = 0 and it looks like we are done. But,
556 in fact, we need to add 1 more to the quotient. Now, it turns
557 out that this happens if and only if the original value x is
558 an exact multiple of y. So, to avoid a three instruction test at
559 the end, instead use 1 instruction to add 1 to x at the beginning. */

201 . dividend==-2**31 and divisor==-1 and routine is $$divoI
202 . (traps with ADDO 26,25,0)

204 . NONE

206 PERMISSIBLE CONTEXT:
207 . Unwindable.
208 . Suitable for internal or external millicode.
209 . Assumes the special millicode register conventions.

211 DISCUSSION:
212 . Branchs to other millicode routines using BE
213 . $$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
214 .
215 . For selected divisors, calls a divide by constant routine written by
216 . Karl Pettis. Eligible divisors are 1..15 excluding 11 and 13.
217 .
218 . The only overflow case is -2**31 divided by -1.

991/* TRUNCATED DIVISION BY SMALL INTEGERS
992
993 We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
994 (with y fixed).
995
996 Let a = floor(z/y), for some choice of z. Note that z will be
997 chosen so that division by z is cheap.
998
999 Let r be the remainder(z/y). In other words, r = z - ay.
1000
1001 Now, our method is to choose a value for b such that
1002
1003 q'(x) = floor((ax+b)/z)
1004
1005 is equal to q(x) over as large a range of x as possible. If the
1006 two are equal over a sufficiently large range, and if it is easy to
1007 form the product (ax), and it is easy to divide by z, then we can
1008 perform the division much faster than the general division algorithm.
1009
1010 So, we want the following to be true:
1011
1012 . For x in the following range:
1013 .
1014 . ky <= x < (k+1)y
1015 .
1016 . implies that
1017 .
1018 . k <= (ax+b)/z < (k+1)
1019
1020 We want to determine b such that this is true for all k in the
1021 range {0..K} for some maximum K.
1022
1023 Since (ax+b) is an increasing function of x, we can take each
1024 bound separately to determine the "best" value for b.
1025
1026 (ax+b)/z < (k+1) implies
1027
1028 (a((k+1)y-1)+b < (k+1)z implies
1029
1030 b < a + (k+1)(z-ay) implies
1031
1032 b < a + (k+1)r
1033
1034 This needs to be true for all k in the range {0..K}. In
1035 particular, it is true for k = 0 and this leads to a maximum
1036 acceptable value for b.
1037
1038 b < a+r or b <= a+r-1
1039
1040 Taking the other bound, we have
1041
1042 k <= (ax+b)/z implies
1043
1044 k <= (aky+b)/z implies
1045
1046 k(z-ay) <= b implies
1047
1048 kr <= b
1049
1050 Clearly, the largest range for k will be achieved by maximizing b,
1051 when r is not zero. When r is zero, then the simplest choice for b
1052 is 0. When r is not 0, set
1053
1054 . b = a+r-1
1055
1056 Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
1057 for all x in the range:
1058
1059 . 0 <= x < (K+1)y
1060
1061 We need to determine what K is. Of our two bounds,
1062
1063 . b < a+(k+1)r is satisfied for all k >= 0, by construction.
1064
1065 The other bound is
1066
1067 . kr <= b
1068
1069 This is always true if r = 0. If r is not 0 (the usual case), then
1070 K = floor((a+r-1)/r), is the maximum value for k.
1071
1072 Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
1073 answer for q(x) = floor(x/y) when x is in the range
1074
1075 (0,(K+1)y-1) K = floor((a+r-1)/r)
1076
1077 To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
1078 the formula for q'(x) yields the correct value of q(x) for all x
1079 representable by a single word in HPPA.
1080
1081 We are also constrained in that computing the product (ax), adding
1082 b, and dividing by z must all be done quickly, otherwise we will be
1083 better off going through the general algorithm using the DS
1084 instruction, which uses approximately 70 cycles.
1085
1086 For each y, there is a choice of z which satisfies the constraints
1087 for (K+1)y >= 2**32. We may not, however, be able to satisfy the
1088 timing constraints for arbitrary y. It seems that z being equal to
1089 a power of 2 or a power of 2 minus 1 is as good as we can do, since
1090 it minimizes the time to do division by z. We want the choice of z
1091 to also result in a value for (a) that minimizes the computation of
1092 the product (ax). This is best achieved if (a) has a regular bit
1093 pattern (so the multiplication can be done with shifts and adds).
1094 The value of (a) also needs to be less than 2**32 so the product is
1095 always guaranteed to fit in 2 words.
1096
1097 In actual practice, the following should be done:
1098
1099 1) For negative x, you should take the absolute value and remember
1100 . the fact so that the result can be negated. This obviously does
1101 . not apply in the unsigned case.
1102 2) For even y, you should factor out the power of 2 that divides y
1103 . and divide x by it. You can then proceed by dividing by the
1104 . odd factor of y.
1105
1106 Here is a table of some odd values of y, and corresponding choices
1107 for z which are "good".
1108
1109 y z r a (hex) max x (hex)
1110
1111 3 2**32 1 55555555 100000001
1112 5 2**32 1 33333333 100000003
1113 7 2**24-1 0 249249 (infinite)
1114 9 2**24-1 0 1c71c7 (infinite)
1115 11 2**20-1 0 1745d (infinite)
1116 13 2**24-1 0 13b13b (infinite)
1117 15 2**32 1 11111111 10000000d
1118 17 2**32 1 f0f0f0f 10000000f
1119
1120 If r is 1, then b = a+r-1 = a. This simplifies the computation
1121 of (ax+b), since you can compute (x+1)(a) instead. If r is 0,
1122 then b = 0 is ok to use which simplifies (ax+b).
1123
1124 The bit patterns for 55555555, 33333333, and 11111111 are obviously
1125 very regular. The bit patterns for the other values of a above are:
1126
1127 y (hex) (binary)
1128
1129 7 249249 001001001001001001001001 << regular >>
1130 9 1c71c7 000111000111000111000111 << regular >>
1131 11 1745d 000000010111010001011101 << irregular >>
1132 13 13b13b 000100111011000100111011 << irregular >>
1133
1134 The bit patterns for (a) corresponding to (y) of 11 and 13 may be
1135 too irregular to warrant using this method.
1136
1137 When z is a power of 2 minus 1, then the division by z is slightly
1138 more complicated, involving an iterative solution.
1139
1140 The code presented here solves division by 1 through 17, except for
1141 11 and 13. There are algorithms for both signed and unsigned
1142 quantities given.

1161 Now, the algorithm for 7, 9, and 14 is an iterative one. That is,
1162 a loop body is executed until the tentative quotient is 0. The
1163 number of times the loop body is executed varies depending on the
1164 dividend, but is never more than two times. If the dividend is
1165 less than the divisor, then the loop body is not executed at all.
1166 Each iteration adds 4 cycles to the timings.

1468 r = z mod x = 0
1469
1470 so choose b = 0
1471
1472 Also, in order to divide by z = 2**24-1, we approximate by dividing
1473 by (z+1) = 2**24 (which is easy), and then correcting.
1474
1475 (ax) = (z+1)q' + r
1476 . = zq' + (q'+r)
1477
1478 So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
1479 Then the true remainder of (ax)/z is (q'+r). Repeat the process
1480 with this new remainder, adding the tentative quotients together,
1481 until a tentative quotient is 0 (and then we are done). There is
1482 one last correction to be done. It is possible that (q'+r) = z.
1483 If so, then (q'+r)/(z+1) = 0 and it looks like we are done. But,
1484 in fact, we need to add 1 more to the quotient. Now, it turns
1485 out that this happens if and only if the original value x is
1486 an exact multiple of y. So, to avoid a three instruction test at
1487 the end, instead use 1 instruction to add 1 to x at the beginning. */
