InfiniBand is widely used as a low-latency and high-bandwidth network for high performance computing (HPC) clusters. However, power consumption and system cost become large in exchange for high performance on small-scale clusters or embedded systems. To cope with these problems, we use PCI Express (PCIe) technology as a direct communication link between computing nodes. Point-to-point bidirectional...
We have proposed a power-aware, high-performance, dependable communication link using PCI Express as a direct communication device, referred to as PEARL, for application in a wide range of parallel processing systems from high-end embedded system to small-scale high-performance clusters. In the present study, we describe the structure and function of a communicator chip, referred to as the PEACH chip,...
A heterogeneous multicore system-on-chip (SoC) has been developed for high-definition (HD) multimedia applications that require secure DRM (digital rights management). The SoC integrates three types of processors: two specific-purpose accelerators for cipher and high-resolution video decoding; one general-purpose accelerator (MX); and three CPUs. This is how our SoC achieves high performance and low...
