6551 Core available?

Post by brain »

Anyone know of a Verilog 6551 core or a Verilog project with a Verilog 6551 implemented into the project?

I figured I'd check before I get too far on implementing one.

I searched on here, but only found a PIC implementation thread.

Here are just a few of the many hundreds of potential leads suggested by my evil search engine:

Not sure if it's of interest, but there was a 6850 core included as part of a 6809 project here: http://opencores.org/project,system09 The 6850 has similar capabilities and a similar bus interface to the 6551.

Note that you'll have to join opencores.org to view the project, but it's free and an excellent resource for the FPGA experimenter anyway.

This one is my postThis one isn't a 6551. I found a slew of general purpose uart Verilog... This one is my post

Hmmm, the 6850 is close (only 2 registers, as I recall). I'll see if I can adapt.
