Post by thread:[PIC]: PIC on FPGA?

Hi, Anyone tried something like trying to implement a PIC on an FPGA? Thanks for your info. Regards, S.

Very nice chap called Thomas.A.Coonan posted a file called SYNTHPIC.ZIP on his web site. This file had a VHDL core for PIC CPU and couple of other VHDL files for I/O ports and some test files. I implemented them with some modifications on Xilinx 4005 and manage to get 40Mhz clock speed. It was fun. Check http://www.mindspring.com/~coonan, I am sure file is still there. If not I will try and find it on my old hard disk. Regards, Jay > > > > -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

I looked closely at this a few months back. It was an impressive piece of work. I did find a couple of small bugs in the VHDL. I corresponded with Mr. Coonan and he was going to fix them. I don't know if the updated code has been posted. Bob Ammerman RAm Systems (contract development of high performance, high function, low-level software) {Original Message removed}

I went on a hunt... Here is the corrected URL: http://www.bomis.com/rings/Mhardware-open_source-computers/20 The bug fixes listed include the ones I found: - Generalized PC write so that you can do fancy computed-goto types of things - Fixed STATUS register update. For example, Clearing STATUS actually now causes Z to be set Bob Ammerman RAm Systems (contract development of high performance, high function, low-level software) {Original Message removed}

I hope you find these other links interesting (even though they describe non-PIC processors).

Hi, The site doesn't exist. Could you perhaps send the file to me? Thanks. Regards, S. Sinha (Saurabh) Tel/Fax: (012) 343-4912 Cell: 0825405577 E.Mail: ssinhaspam_OUTIEEE.ORG Visit: http://home.mweb.co.za/si/sinha ICQ: 82010326 {Original Message removed}
