Architectural Overview
The TMS320C28x
t
is one of several fixed-point generations of digital signal
processors (DSPs) in the TMS320 family. The C28x
t
is source-code and ob-
ject-code compatible with the C27x
t
. In addition, much of the code written for
the C2xLP CPU can be reassembled to run on a C28x device.
The C2xLP CPU is used in all TMS320F24xx and TMS320C20x DSPs and
their derivatives. This document refers to C2xLP as a generic name for the
DSP CPU used in these devices.
This chapter provides an overview of the architectural structure and compo-
nents of the C28x CPU.
