Overview
Here is a high-level overview of the dsPIC33A core:
The Bus Matrix manages all the flow of instructions and data between the Central Processing Unit (CPU) and the unified memory interface.
A 5-stage instruction pipeline with speculative execution and simple branch prediction is used to reduce instruction execution latency. The instructions will be sent to the CPU and either be executed by the CPU or the Digital Signal Processing (DSP) engine or it will send an equivalent instruction to the Floating Point Unit (FPU), which operates on its own pipeline.
