  1. A Generic PCI Based FPGA Coprocessor?

    graveyhead asks: "Inspired by a recent Slashdot article, I came across this fantastic package from the fine students in the Configurable Computing Laboratory at BYU: JHDL, which is a set of open source FPGA CAD tools. I am writing a proposal for a prototype system and I have a requirement for a 32 or 64 bit PCI card compatible with JHDL. I do not require any IP cores (which Xilinx seems to want to sell me hundreds of 'em), since our project uses its own custom cores. Also, I will not be building additional hardware around the FPGA processor, so the package needs to be fully self-contained. I simply need the ability to use JHDL to program the FPGA device over PCI under Linux, execute my circuit with parameterized values, and return the result. I found these boards, but I'm not sure which is appropriate or compatible, or if there are better alternatives that I am not finding in a similar price range (up to USD2000). Preferably, I want a chip with lots (1-10M+) of programmable gates."

  2. Anyone Using JHDL for Programmable Logic?

    gte910h asks: "I am an embedded developer who is learning how to program programmable logic devices (CPLD's and FPGA's). I have looked at VHDL and other Hardware Description Languages, but they seem so obtuse compared to C or Java. Has anyone tried any of the tools based off of general purpose programming languages, like JHDL. Do they work as well as VHDL and other HDL's? These would make things this type of development acessable to more people if they work well enough." Are packages similar to JHDL available for other languages?
