Subject: How Would You Design An Over 64-bit Multiplier-Accumulator (MAC)?
Dear John,
I would love to hear from your readers how they'd design a large Multiplier-
Accumulator (MAC) for over 64-bit operands. I'm considering Module
Compiler. Our implementation technology is not decided yet, but I'm
guessing 0.18um or smaller. We're targeting a freq in excess of 133MHz.
In terms of speed/power, any pointers/numbers would be greatly appreciated,
as also techniques to verify this type of circuit. (Obviously, we're not
circuit designers, and would probably do a very poor job at a custom
multiplier.) Ideas? Pointers?
- Neel Das
