1File: minver.c
2Original provenience: SNU-RT Benchmark Suite for Worst Case Timing Analysis
3
42016-02-26:
5 - Added TACLeBench header to line 1
6 - Rename global variable a to minver_a
7 - Rename global variable b to minver_b
8 - Rename global variable c to minver_c
9 - Rename global variable aa to minver_aa
10 - Rename global variable a_i to minver_a_i
11 - Rename global variable e to minver_e
12 - Rename global variable det to minver_det
13 - Renamed function minver to minver_minver
14 - Renamed function mmul to minver_mmul
15 - Renamed function fabs to minver_fabs
16 - Renamed function main to minver_main
17 - Created new function main, calling minver_init, minver_main and
18 returning minver_return
19 - Reordered functions in source code: initialization- and
20 return-value-related functions first, followed by algorithm core
21 functions, followed by main functions
22 - Applied code formatting with astyle as in the example
23
242016-03-09:
25 - Removed static keyword for global variables
26 - Renamed global variables, prepended adpcm_dec
27
28 2016-05-23:
29 - Check sum added and checked against the expected value
30
31 2016-05-25:
32 - Corrected expected value \ No newline at end of file

3 This program is part of the TACLeBench benchmark suite.
4 Version V 1.x
5
6 Name: adpcm_dec
7
8 Author: Sung-Soo Lim
9
10 Function:
11 CCITT G.722 ADPCM (Adaptive Differential Pulse Code Modulation)
12 algorithm.
13 16khz sample rate data is stored in the array test_data[SIZE].
14 Results are stored in the array compressed[SIZE] and result[SIZE].
15 Execution time is determined by the constant SIZE (default value
16 is 2000).
