File: adpcm_enc.c
Original provenience: C Algorithms for Real-Time DSP by P. M. Embree
2016-03-07:
- Rename adpcm_encode to adpcm_enc
- Add generic TACLeBench header
- Remove #define Seoul_Mate around main
- Remove swedish comment after setting frequency to 2000
- Introduce adpcm_enc_init, adpcm_main, adpcm_return
- Make test_data and compressed global variables
2016-04-26:
- Remove forward declarations of functions gaussian, iir_filter, fir_filter,
fft, setup_codec, key_down, int_enable, int_disable, flags, getinput,
sendout, which are never defined
- Remove commented declarations of invqxl and invqah
- Remove unused structure COMPLEX
- Remove prefix my_ from functions names my_fabs, my_cos, my_sin, my_abs
- Prefix all global symbols with benchmark name
- Remove variables accumc and accumd together with their initialization loop,
since they are never read
- Remove unused variables xs and xd
- Remove unused array wl_table
- Remove unused variable rs and rh
- Remove unused variables and their initializations (only required for decoder):
ilr, yl, rl, dec_deth, dec_del_bpl, dec_plt, dec_plt1, dec_plt2, dec_szl,
dec_spl, dec_sl, dec_rlt1, dec_rlt2, dec_rlt, dec_al1, dec_al2, dl, dec_nbl,
dec_yh, dec_dh, dec_nbh, dec_rh2, dec_ah1, dec_ah2, dec_ph, dec_sph, dec_sh,
dec_rh, dec_ph1, dec_ph2,
- Add addition on each element of input data with volatile variable to
avoid constant-propagation optimizations through the compoiler
- Add computation of check sum
- Add return return statement: zero if check sum is correct
2016-05-20:
- Apply code formatting with astyle
