Architecture Overview
The core processor in the C6xx is a medium performance mixed signal proces-
sor with enhanced microcontroller features and a limited DSP instruction set.
In addition to its basic multiply/accumulate structure for DSP routines, the core
provides for a very efficient handling of string and bit manipulation. A unique
accumulator-register file provides additional scratch pad memory and mini-
mizes memory thrashing for many operations. Five different addressing
modes and many short direct references provide enhanced execution and
code efficiency.
The basic elements of the C6xx core are shown in Figure 2–1. In addition to
the main computational units, the core’s auxiliary functions include two timers,
an eight-level interrupt processor, a clock generation circuit, a serial scan-port
interface, and a general control register.
