      Software Managed Distributed Memories in MPPAs
      International Conference on Field Programmable Logic and Applications
      Aug 2010
      When utilizing reconfigurable hardware there are many applications that will require more memory than is available in a single hardware block. While FPGAs have tools and mechanisms for building logically larger memories, it often requires developer intervention on word-oriented devices like Massively Parallel Processor Arrays (MPPAs). We examine building larger memories on the Ambric MPPA. Building an efficient structure requires low-level development and analysis of latency and bandwidth effects of network and protocol choices. We build a network that only requires only five instructions per transaction after optimization. The resource use and performance suggests architectural enhancements that should be considered for future devices.

      Impulse C vs. VHDL for Accelerating Tomographic Recronstruction
      th IEEE Annual International Symposium on FieldProgrammable Custom Computing Machines
      Jan 2010
      While traditional methods of designing FPGA applications have relied on schematics or HDL, much interest has been shown in C-to-FPGA tool flows that allow users to design FPGA hardware in C. We evaluate a C-to-FPGA tool flow (Impulse C) by analyzing the performance of three independent implementations of the Computed tomography (CT) filtered backprojection (FBP) algorithm developed using C, Impulse C, and VHDL respectively. In the process, we compare the design process of Impulse C versus HDL, and discuss the benefits and challenges of using Impulse C. In addition, we explore the benefits of tightly-coupled FPGA acceleration offered by the XtremeData XD1000. The results of this paper demonstrate that Impulse C designs can achieve over 61x i
