In this paper we investigate several common bus architectures and measure effective bandwidth between High Performance Computing cores and off-chip memory. Contributions of this paper include (i) characterizing the behavior of four common organizations using off-the-shelf IP cores, (ii) an investigation of the effect of multiple computational cores sharing the bus structures, and (iii) the development...
A high performance RLS lattice filter with evaluation of an unknown order of identified system was implemented as an accelerator PCORE for Xilinx EDK. The accelerator hardware can fully exploit parallelisms in the algorithm and remove load from a microprocessor. The EDK integration allows effective programing and debugging of a hardware accelerated DSP applications. The optimal logarithmic number...
Structured ASICs have emerged as a mid-way between cell-based ASICs with high NRE costs and FPGAs with high unit costs. Though the structured ASIC fabric attacks mask and other fixed cost it does not solve verification, particularly physical verification issues with ASICs or logic errors missed by simulation which would require re-spins. These can be avoided by testing in-system with an FPGA and migrating...
