can any one help out in the following problem.

I have to give my inputs dynamically from keyboard whan running as we
give in cprogram and i have to display my outputs on the monitor.
exactly similar to stdin and stdout in C.

i shall be thankful to you

If you want to do it entirely in VHDL, it will be difficult... You will unfortunately need a core to drive the monitor with video signals, a core to grab input from the keyboard, and a look up table to map keys to pixel patterns, and a small processor/FSM to process everything.. If this is your first time doing VHDL, it might be a little difficult.. Another alternative is to implement a suitable microcontroller in an FPGA, and if it's fast enough, you can do all that, and generate the video signals in software... That takes the complexity out from the hardware, into the software.. Cheers..

I have never tried the later, but it looks interesting.

Hi

i want very fast 10 bit adder(vhdl source code).if any one knows can
help me.

with regards
john

In what level? For what pourpose? On Apr 11, 2005 1:35 PM, johnpal at gmail.com johnpal at gmail.com> wrote:
