چکیده

Recently network bandwidth that is available at home or o ce increases rapidly. However, processing overheads of communication are too large to exploit the huge bandwidth e ciently. In this paper, we propose an innovative network-interface architecture \Memory-Based Processor II (MBP2)" that enables application programs to execute send/receive without system-calls under proper protection and virtualization. The MBP2 adopts memory-based architecture where direct communication between application spaces is performed without kernel services. We also introduce a built-in microprocessor \Casablanca" that can cooperate e ciently with DMA and Interrupt mechanisms.

Cost-aware Topology Customization of Mesh-based Networks-on-Chip

Nowadays, the growing demand for supporting multiple applications causes to use multiple IPs onto the chip. In fact, finding truly scalable communication architecture will be a critical concern. To this end, the Networks-on-Chip (NoC) paradigm has emerged as a promising solution to on-chip communication challenges within the silicon-based electronics. Many of today’s NoC architectures are based...
