The C28x is one of several members of the fixed-point generations of digital signal processors
(DSPs) in the TMS320 family. The C28x is source-code and object-code compatible with the
C27x. In addition, the C28x is source code compatable with the 24x/240x DSP and previously
written code can be reassembled to run on a C28x device. This allows for migration of existing
code onto the C28x.
