Using current CLB/State numbers:
Of 1718 Control CLBs, only 83 used for CSTATE
1635 * 32 bits/CLB = 52320 uCode bits
Will guesstimate an average of 3 uWords per
instruction (would be based on average # of machine
cycles per instruction).
uCode width = datapath control lines + next uAddress selection
= 91 + (9 bits direct address + 5 bits condition)
178 opcodes * 3 uWords * 105 = 56070 bits
Would Microcode Reduce Control Size?
