I am trying to code a radix 4 SRT divider and I am stuck with the quotient selection logic. It seems that the quotient is slected based on a p-d lookup table. Intel had used a PLA to store the p-d entries many years ago. I found that the number of entries are about 1000 and I was wondering whether its possible to store this table in some fast memory like a ROM or RAM so that it can be read within 1 cycle - its important to be readable in 1 cycle as the division will be too slow otherwise.
