Abstract

A method to optimize instructions in embedded real-time java processors is proposed. It can reduce the CPI (Cycles per Instruction) and simplify the implementation of complex instructions, as well as make the WCET (Worst Case Execution Time) of the optimized instructions more predictable. Because this method optimizes instruction itself, it can be used together with other architectural optimization methods such as pipeline or out-of-order execution etc.
