- KonferenzbeitragSub-word handling in data-parallel mapping(ARCS 2012 Workshops, 2012) Psychou, Georgia; Fasthuber, Robert; Hulzink, Jos; Huisken, Jos; Catthoor, FranckyData-parallel processing is a widely applicable technique, which can be implemented on different processor styles, with varying capabilities. Here we address single or multi-core data-parallel instruction-set processors. Often, handling and reorganisation of the parallel data may be needed because of diverse needs during the execution of the application code. Signal word-length considerations are crucial to incorporate because they influence the outcome very strongly. This paper focuses on the broader solution space of selecting sub-word lengths (at design time) including especially hybrids, so that mapping on these data parallel single/multi-core processors is more energy-efficient. Our goal is to introduce systematic exploration techniques so that part of the designers effort is removed. The methodology is evaluated on a representative application driver for a number of data-path variants and the most promising trade-off points are indicated. The range of throughput-energy ratios among the different mapping implementations is spanning a factor of 2.2.
