8-1 Pipeline Operation
Pipeline Operation
Two characteristics of the’C3x that contribute to its high performance are:
- Pipelining
- Concurrent I/O and CPU operation
The following four functional units control ’C3x operation:
- Fetch
- Decode
- Read
- Execute
Pipelining is the overlapping or parallel operations of the fetch, decode, read,
and execute levels of a basic instruction.
The DMA controller decreases pipeline interference and enhances the CPU’s
computational throughput by performing input/output operations.
