Scalable Memory Hierarchies for Embedded Manycore Systems
As the size of FPGA devices grows following Moore’s law, it becomes possible to put a complete manycore system onto a single FPGA chip. The centralized memory hierarchy on typical embedded systems in which both data and instructions are stored in the off-chip global memory will introduce the bus contention problem as the number of processing cores increases. In this work, we present our explora...
متن کاملSoftware-assisted cache mechanisms for embedded systems
Embedded systems are increasingly using on-chip caches as part of their on-chip memory system. This thesis presents cache mechanisms to improve cache performance and provide opportunities to improve data availability that can lead to more predictable cache performance. The first cache mechanism presented is an intelligent cache replacement policy that utilizes information about dead data and da...
متن کاملFast Instruction Memory Hierarchy Power Exploration for Embedded Systems
A typical instruction memory design exploration process using simulation tools for various cache parameters is a rather time-consuming process, even for low complexity applications. In order to design a power efficient memory hierarchy of an embedded system, a huge number of system simulations are needed for all the different instruction memory hierarchies, because many cache memory parameters ...
متن کاملA Performance Evaluation of Memory Hierarchy in Embedded Systems
The increasing speed gap between processors and memory makes the design of memory hierarchy one of the critical issues in general purpose embedded systems. As memory requirements for embedded applications grow, especially in emerging area of handheld multimedia devices, cache memories become crucial for providing high performance and reducing power. This paper describes a performance evaluation...
متن کاملDesign of Scalable PGAS Collectives for NUMA and Manycore Systems
The increasing number of cores per processor is turning multicore-based systems in pervasive. This involves dealing with multiple levels of memory in NUMA systems, accessible via complex interconnects in order to dispatch the increasing amount of data required. The key for efficient and scalable provision of data is the use of collective communication operations that minimize the impact of bott...
