This library package provides several forward error correction (FEC) decoders
|
|
and accelerated primitives useful in digital signal processing (DSP).
|
|
Except for the Reed-Solomon codecs, these functions take full advantage of
|
|
the MMX, SSE and SSE2 SIMD instruction sets on Intel/AMD IA-32 processors
|
|
and the Altivec/VMX/Velocity Engine SIMD instruction set on the
|
|
G4 and G5 PowerPC.
|
|
The library includes Viterbi decoders for the following convolutional codes:
|
|
rate 1/2 k=7
|
|
rate 1/2 k=9
|
|
rate 1/6 k=15 ("Cassini")
|
|
plus two Reed-Solomon encoder-decoders:
|
|
one optimized for the (255,223) CCSDS standard code
|
|
a general purpose encoder/decoder for arbitrary RS codes
|
|
and three low-level 16-bit DSP support routines:
|
|
signed dot product
|
|
peak detection
|
|
sum-of-squares (energy) computation
