hi
unfortnatly i dont know VHDl programing. i need a seven sgment counter (4 digit) and a multiple cycle microprogrammed computer (CPU) designed in AHDL or VHDL.
Wow, you'll find a lot of dificult in implementing this...Unfurtunally i don't have this code (of CPU), but you can find a quite similar one in "VHDL cook Book"...Search this book in e-Book area...The shift register you can find in "Digital Design", by John Wakerly...A very good book. In AHDL I don't know where you can find...Good luck!!!
