Exploring Processor Parallelism: Estimation Methods and Optimization Strategies

Automatic optimization of Application-Specific Instruction-set Processor (ASIP) architectures mostly focuses on the internal memory hierarchy design, or the extension of reduced instruction-set architectures with complex custom operations. This paper focuses on Very Long Instruction Word (VLIW) architectures and, more specifically, on automating the selection of an application specific VLIW issue-width. The issue-width selection strongly influences all the important processor properties (e.g. processing speed, silicon area, and power consumption). Therefore, an accurate and efficient issue-width estimation and optimization are some of the most important aspects of VLIW ASIP design.
