Scratch-pad memory (SPM) is widely used in embedded systems. It is a topical and crucial subject to reduce power consumption for SPM systems, since high power consumption can reduce systems reliability and increase the cost and size of heat sinks. In this paper, we propose an effective approach of power reducing to scale down voltage and frequency as much as possible. We first pipelined data transference...
In this paper, we develop a compiler-assisted thermal-aware data allocation algorithm to improve the reliability of embedded systems with cache and SPM (scratch-pad memory). Our basic idea is to distribute the workload evenly between the cache and SPM in order to alleviate the temperature hot spots in the on-chip memory system. In the algorithm, considering the size of SPM, we first divide the loop...
Scratch-pad memory (SPM), a small fast software-managed on-chip SRAM (static random access memory), is widely used in embedded systems. With the ever-widening performance gap between processors and main memory, it is very important to reduce the serious off-chip memory access overheads caused by transferring data between SPM and off-chip memory. In this paper, we propose a novel compiler-assisted...
