Program Control
Several features provide program control:
-
The program controller of the CPU decodes instructions, manages the
pipeline, stores the status of operations, and decodes conditional opera-
tions. Elements involved in program control are the program counter, the
status registers, the stack, and the address-generation logic.
-
Software mechanisms used for program control include branches, calls,
conditional instructions, a repeat instruction, reset, and interrupts.
For descriptions of these program control features, see Chapter 5,
