use the cam for vcu118
Winters123 opened this issue · 1 comments
Hi Alex,
I'm considering using this cam on vcu118 to replace the one provided by Xilinx. The reason is that I found xapp1151 doesn't work as it should on vcu118 (250MHz). It would be great if you can answer some of the questions I have:
- Is this cam able to work on 250MHz on ultrascale+ FPGAs like vcu118?
- Could the data width be extended? For example, we would like it to be extended to 201b (not aligned with 2^).
- Is it possible to support ternary mode using this cam?
Happy new year and thanks in advance.

Xiangrui
TBH, this repo is more of a proof of concept than anything else. I have not used these modules for any projects yet, so I'm not sure what the performance is like. You'll probably just have to test it out. This is basically just an implementation of that app note anyway, so I'm not sure if the performance would be significantly different.
I think you can put whatever you want for the data width, doesn't have to be a power of two. But it might get very large (and probably also slow).
I think there are ways of converting a binary CAM into a ternary CAM. I have not looked in to that myself, though.
