Pipelining and Bypassing in a VLIW Processor

This paper describes issues involved in the bypassing mechanism for a VLIW processor and its relation to the pipeline structure of the processor. We will first describe the pipeline structure of our processor and analyze its performance and compare it to typical RISC-style pipeline structures given the context of a processor with multiple functional units. Next, we shall study the performance effects of various bypassing schemes in terms of their effectiveness in resolving pipeline data hazards and their effect on the processor cycle time.
