Abstract
The update of embedded processor may introduce new function unit, new coprocessor, or even new additional DSP. In many cases, software application can’t be fully rebuilt to utilize these new resources. This paper describes a novel framework, called Runtime Instruction Rescheduling (RIR), to solve this problem. RIR can find hot spots in binary codes, build a large instruction window to generate trace, reschedule and optimize instructions in traces. Different scheduling policies have been simulated. Shown from detailed simulation, RIR helps the old binary codes benefit from new hardware resources.
