The goal of the High-Level Architecture (HLA) is to promote interoperability and reuse between federates. In this context, HLA fills the role of middleware in the domain of distributed simulation. However, in many respects, HLA falls short of its promised potential. These problems can be attributed in part to the HLA standard itself, which leaves a number(More)
This work quantifies the performance benefit of vectorized versions of the ITU-T G.729A and G.723.1 speech coding standards. Architecture-level experimentation with the addition of custom vector instructions indicates a reduction in the dynamic instruction count of the workloads of the order of 51% and 65% respectively at a vector register length of sixteen(More)
This paper presents the results of an investigation of employing configurable scalar and vector coprocessors to accelerate the G.723.1 and the G.729A speech coders. Architecture exploration has produced a reduction by up to 70% of the total number of instructions executed following the introduction of custom instructions. The accelerators are designed to be(More)
