Newbe question ... how to integrate an FPGA based logic cirucit with a C/C++ program on posix

Thank you for your response.

I am surely going to deep dive into OpenCL to figure out what can be done with it ...

From what I read, and if i understood this correctly, it seems that OpenCL is an alternative to hardware description languages such as Verilog. Encoded OpenCL calls are implemented in FPGA, while appearing to the developer as specialized C/C++ library functions.

I guess, I had a different kind of "architecture" in mind -- a way to to create an own FPGA "circuit" -- using, for example, Verilog, and then to have a way to memory map the FPGA to a CPU memory on a standard PC.

Perhaps those acceleration cards are close to what i had in mind ...

thank you,

Dan
