We present an open source stack for the development of custom FPGA boards, primarily but not limited to PCI Express interconnects. Supporting current Linux distributions, the stack consists of a PCI driver, an IP core for a DMA engine, a hardware abstraction library for IO operations, and a buffer management library for efficient handling of data transfers between an application and a FPGA design...
Reconfigurable logic is a flexible solution for offloading some of computations from a processor. In particular, in applications where small kernels are repeated often, e.g., in DSP. However, the traditional development style for reconfigurable logic is hardware design, while application code for CPU is software, thus there is need for an design methodology for converting software partition to an...
Specialized hardware accelerators are enabling today's System on Chip (SoC) platforms to target various applications. In this paper we show that as these SoCs evolve in complexity and usage, the programming models for such platforms need to evolve beyond the traditional driver oriented architecture. Using a test set up that employs a programmable FPGA based accelerator to implement one of the critical...
