I am Nageswara rao i looking for VHDL clock programig type project ----- Original Message ----- From: akfoo at h... To: cores at o... Date: Mon, 26 Nov 2001 03:57:47 +0100 Subject: Re: [oc] 8051 VHDL models search
JM: Thank for your information again. I will going to look for the book that you recomemded. :-) By the way, I still haven't received your attached zip file for the sources of Mayer's 8051 VHDL (synthesizable). Could you please send it to me again? For your information, my email address is as below: akfoo_uk at h... If I have any latest information for it, I will forward to you as well. :-) Thank alot!!
