Technology trends are leading to increasing number of cores on chip. All these cores inherently share the DRAM bandwidth. The on-chip and off-chip cache or memory resources are limited and in many situations, cannot hold the working set of the threads running on all these cores. This situation makes DRAM bandwidth a critical shared resource. Hence computer designers are faced with an increasing Processor...
Architecture and memory system are two important factors that influence the performance of parallel processing systems. This paper based on a proposed real scalable, triple-based multi-core architecture providing hardware level support for object-oriented methodology. However, the memory wall is still the bottleneck of the whole system performance. We present hierarchical shared memory (HSM) architecture...
It is well known fact that multi-core processor architecture is the mainstream of the next-generation microprocessor architecture and actualizes by chip multi-core processors (CMP). As the number of cores per processor and the number of threaded applications increase, the performance of more and more applications will be limited by the processor's memory bandwidth. DRAM memory is a major resource...
