Exposed-datapath architectures yield small, low-power processors that trade instruction word length for aggressive compile-time scheduling and a high degree of instruction-level parallelism. In this paper, we present a general-purpose parallel accelerator consisting of a main processor and eight symmetric clusters, all in a single core. Use of a lightweight and memory-efficient application programming interface allows for the first high-performance program executing both sequential and data-parallel code on the same TTA processor. We use the processor for LDPC encoding, a popular method of forward error correction. Demonstrating the flexibility of software-defined radio, we benchmark the processor with two programs, one which can handle almost any sort of LDPC code, and another which is optimized for a specific standard. We achieve a throughput of 5 Mb/s with the flexible program and 92 Mb/s with the standard-specific one, while consuming only 95 mW at a clock frequency of 1175 MHz. |
