New IP development

Hello, I am interested in developing some instructions which can do the bignum operations (like adding two operands of 1024 bit) and hence by plan to implement a simple Full Adder like this: ...

Hello,

Really appreciate for the response.

If you only have a handful of operands you want to use (but frequently), then you could possibly look into using dual port onchip memory, with the NIOS/SGDMA on one port for reading/writing results, and the other port dedicated for your Avalon-MM Master to use. If it will fit in your device, a RAM width of 1024-bits might provide the highest throughput.

As far as how to control your new IP, you could do something like add custom instructions which take 32-bit addresses (pointers) to the operands which your new logic would independently fetch/store results.
