چکیده

To meet increasing performance requirements of DSP applications, application specific processor designs, e.g. function unit (FU) duplication and register file (RF) distribution, are widely used in the design of DSP processors. In this paper, an application specific approach is proposed for the design of interconnection network in such DSP processors. By extracting the scheduling information of DSP applications, we decide the minimal number of required partially connected buses. Without impacting the performance and increasing the hardware cost, it provides optimized future scheduling flexibility. Our results show that reductions of 40% in the number of required global buses and 60% in wire segments can be achieved.

Permutation Networks as Application Specific Interconnection Networks for SIMD DSPs

Parallelization is one possibility to enhance the performance in processors. For singleinstruction-multiple-data (SIMD) processors one requirement is the possibility to parallelize algorithms so that one algorithm is partitioned to the parallel processing units of the processor. This means that data has to be exchanged between the processing units. Hence, these separate units have to be connect...

Design and Reliability Analysis of a Class of Irregular Fault-Tolerant Multistage Interconnection Networks

Parallel processing can be used to design high performance computing systems. In a parallel computer inter-connecting processors and linking them efficiently to the memory modules is not an easy task. Therefore, there is a requirement of an interconnection network that provides the desired connectivity and performance at minimum cost. Multistage interconnection networks (MINs) provide cost-effe...

Ultra-Low-Energy DSP Processor Design for Many-Core Parallel Applications

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...
