Instruction Recycling on a Multiple-Path Processor

Processors that can simultaneously execute multiple paths of execution will only exacerbate the fetch bandwidth problem already plaguing conventional processors. On a multiple-path processor, which speculatively executes less likely paths of hard-to-predict branches, the work done along a speculative path is normally discarded if that path is found to be incorrect. Instead, it can be beneficial to keep these instruction traces stored in the processor for possible future
