  • ALU with carry length detection
    Patent number: 4623981
    Abstract: An ALU, performing selected operations on input operands in a predetermined clock cycle, uses means for detecting a carry propagation path greater than a predetermined number of consecutive bit positions to cause a stretching of the clock cycle. Since such a long carry propagation path is detected for only a very small percentage of all operations, the cycle is normally shorter than otherwise possible, AND, thus, the performance of a system using such an improved ALU is increased.
