Texas Instruments TMS320C28x - 2 Central Processing Unit; Status Register ST0

2-1
Central Processing Unit
The central processing unit (CPU) is responsible for controlling the flow of a
program and the processing of instructions. It performs arithmetic, Boolean-
logic, multiply, and shift operations. When performing signed math, the CPU
uses 2s-complement notation. This chapter describes the architecture, regis-
ters, and primary functions of the CPU.
