Summarize the basic features of PIC18The PIC18F implements a two-stage pipeline. The PIC18F CPU fetches the instruction during the first stage. However, during the second stage, the PIC18F CPU while executing the instruction, fetches the next instruction. This is called “two-stage instruction pipelining”, and is used by the PIC18F to increase the speed of instruction execution. When the PIC18F fetches a branch instruction, it clears or flushes the pipeline and executes a new sequence of instructions starting at the new branch address. F pipelining.
