- Well I've scanned my .newsrc for an appropriate group to place this
- question and I came up with this one, if it belongs somewhere else
- please let me know.
-
- I have a circuit design that I need integrated down to 1 or 2 chips
- using FPGA,PLD's or what have you. I don't know much about custom
- or semi-custom chips to know what would be the most cost-effective.
-
- The circuit is input a 24-bit address and must compare it against
- 4 loadable 24-bit address and raise or lower one of four corresponding
- chip select lines. It must do this withing 35 ns at least.
-
- So the chip must have at least 24 input lines and 4*24=96 flip-flops
- . I can't do this with discrete components and must have it in one
- chip because of size considerations.
-
- My question is what would be the most cost-effective way of realizing
- this?
