Introduces an instruction reissue mechanism in order to enhance dynamic data dependence
speculation using data address prediction. Since instructions which are not data-dependent …

As more data value speculation mechanisms are being proposed to speed-up processors,
there is growing pressure on the critical processor structures that must buffer the state of the …

In this paper, we investigate the impact of instructions reissued due to mispredicted data ow
speculation on processor performance. Recently, data dependences are studied to be …

Data speculation refers to the execution of an instruction before some logically preceding
instructions on which it is data dependent. Data speculation implies some form of prediction …

Control speculation refers to the execution of instructions before it has been determined that
they would be executed in the normal flow of execution. Data speculation refers to the …

Compiler-directed data speculation has been implemented on Itanium systems to allow for a
compiler to move a load across a store even when the two operations are potentially aliased …

In this paper, we investigate the impact of instructions reissued due to misspeculated data
dependences on processor performance. Recently, the practice of speculation in resolving …

Superscalar microprocessors obtain high performance by exploiting parallelism at the
instruction level. To effectively use the instruction-level parallelism found in general purpose …

Compiler-controlled speculative execution has been shown to be effective in increasing the
available instruction level parallelism (ILP) found in non-numeric programs. An important …

Recently, the practice of speculation in resolving data dependences has been studied as a
means of extracting more instruction level parallelism (ILP). An outcome of an instruction is …
