3.1.3 Viterbi, Complex Math, and CRC Unit (VCU)

The C28x Viterbi, Complex Math and CRC Unit (VCU) is a fully-programmable block that accelerates the performance of communications-based algorithms by up to a factor of 8× over the C28x CPU alone. In addition to eliminating the need for a second processor to manage the communications link, the performance gains of the VCU provides headroom for future system growth and higher bit rates or, conversely, enables devices to operate at a lower MHz to reduce system cost and power consumption.

For more information, see the TMS320C28x Extended Instruction Sets Technical Reference Manual.

Table 3-3 lists the VCU types, including device-specific differences within each type.
