—A 167-processor computational platform consists of an array of simple programmable processors capable of per-processor dynamic supply voltage and clock frequency scaling, three algorithm-specific processors, and three 16 KB shared memories; and is implemented in 65 nm CMOS. All processors and shared memories are clocked by local fully independent,… (More)
reported lowest energy per bit. Decoder area is 4.84 mm 2 with a final post-layout area utilization of 97%.
Modern applications increasingly require the computation of DSP workloads comprised of a variety of numerically-intensive DSP tasks. These workloads are found in communication, multime-dia, embedded, and wireless applications, and often require very high levels of computation and high energy efficiency. The Asynchronous Array of Simple Processors (AsAP)… (More)
as a JPEG encoder core and a fully compliant IEEE 802.11a/g wireless LAN baseband transmitter.
A Split decoding algorithm is proposed which divides each row of the parity check matrix into two or multiple nearly-independent simplified partitions. The proposed method significantly reduces the wire interconnect and decoder complexity and therefore results in fast, small, and high energy efficiency circuits. Three full-parallel decoder chips for a… (More)
The continuing advances in the performance of network servers make it essential for network interface cards (NICs) to provide more sophisticated services and data processing. Modern network interfaces provide fixed functionality and are optimized for sending and receiving large packets. One of the key challenges for researchers is to find effective ways to… (More)
A 167-processor 65 nm computational platform well suited for DSP, communication, and multimedia workloads contains 164 programmable processors with dynamic supply voltage and dynamic clock frequency circuits, three algorithm-specific processors, and three 16 KB shared memories, all clocked by independent oscillators and connected by configurable… (More)
A reduced complexity LDPC decoding method is presented that dramatically reduces wire interconnect complexity, which is a major issue in LDPC decoders. The proposed split-row method makes column processing parallelism easier to exploit, doubles available row processor parallelism, and significantly simplifies row processors - which results in smaller area,… (More)
