Modern computational workloads require abundant thread level parallelism (TLP), necessitating highly-parallel, many-core accelerators such as General Purpose Graphics Processing Units (GPGPUs). GPGPUs place a heavy demand on the on-chip interconnect between the many cores and a few memory controllers (MCs). Thus, traffic is highly asymmetric, impacting on-chip resource utilization and system performance...
With continued Moore's law scaling, multicore-based architectures are becoming the de facto design paradigm for achieving low-cost and performance/power-efficient processing systems through effective exploitation of available parallelism in software and hardware. A crucial subsystem within multicores is the on-chip interconnection network that orchestrates high-bandwidth, low-latency, and low-power...
Chip Multi-processor (CMP) architectures have become mainstream for designing processors. With a large number of cores, Networks-on-Chip (NOCs) provide a scalable communication method for CMP architectures. NOCs must be carefully designed to meet constraints of power consumption and area, and provide ultra low latencies. Existing NOCs mostly use Dimension Order Routing (DOR) to determine the route...
The high peak OFDM signal out of the linear region of the power amplifier is compressed with fixed scale down ratio instead of clipping. The compressed signal is transmitted using the additional subcarrier and can be restored if the tone detector at the receiver indicates the presence of additional subcarrier. This method shows the better BER performance than the normal clipping method. And also the...
