Abstract :
A study was initiated that investigated detractors to parallelism and implementation constraints associated with the critical paths in the design of fine grain parallel machines. The outcome of the research has been a new machine organization that facilitates and improves parallel instruction issue and possible increases in cycle time and by improving the instruction-level parallelism, using specialized hardware. The authors describe the attributes of the proposed machine organization related to the analysis of instruction sequences for the parallel issue and execution. They also describe the permanent preprocessing in the cache that allows for the determination of instructions for parallel execution prior to the instruction fetch and issues
