Hierarchical coarse-grained stream compilation for software defined radio

Software Defined Radio (SDR) is an emerging embedded domain where the physical layer of wireless protocols is implemented in software rather than the traditional application specific hardware. The operation throughput requirements of current third-generation (3G) wireless protocols are an order of magnitude higher than the capabilities of modern digital signal processors. Due to this steep performance requirement, heterogeneous multiprocessor system-on-chip designs have been proposed to support SDR. These heterogeneous multiprocessors provide difficult challenges for programmers and compilers to efficiently map applications onto the hardware. In this paper, we utilize a hierarchical dataflow programming model, referred to as SPIR, that is designed for modeling SDR applications. We then present a coarse-grained dataflow compilation strategy that assigns a SDR protocol's DSP kernels onto multiple processors, allocates memory buffers, and determines an execution schedule that meets ...
