The C28x VCU enhances the processing power of C2000™ devices by adding additional assemblyinstructions to target complex math, Viterbi decode, and CRC calculations. The VCU instructionsaccelerate many applications, including the following:•Orthogonal frequency-division multiplex (OFDM) used in the PRIME and G3 standards for power linecommunications•Short-range radar complex math calculations•Power calculations•Memory and data communication packet checks (CRC)The VCU features include:•Instructions to support Cyclic Redundancy Checks (CRCs), which is a polynomial code checksum.–CRC8–CRC16–CRC32•Instructions to support a flexible software implementation of a Viterbi decoder–Branch metric calculations for a code rate of 1/2 or 1/3–Add-Compare Select or Viterbi Butterfly in 5 cycles per butterfly–Traceback in 3 cycles per stage–Easily supports a constraint length of K = 7 used in PRIME and G3 standards•Complex math arithmetic unit–Single-cycle Add or Subtract–2-cycle multiply–2-cycle multiply and accumulate (MAC)–Single-cycle repeat MAC•Independent register spac |
