    摘要: An adder circuit includes a number of selectors and an adder. The selectors feed the adder with multiple input data bits. Each of the selectors includes a combination of a multiplexing network and a sense amplifier to select from a number of input values to generate the multiple input data bits. The combination of the multiplexing network and the sense amplifier acts as the state-holding element at the input of the adder, avoiding the overheads of an explicit latch stage.

    摘要: A method and apparatus for an address generation circuit. In one embodiment, the method includes computing a carry-in for at least one group of a predetermined number of bits of a propagate and a generate signal formed from a plurality of logical address components. Once the carry-in is computed, a plurality of conditional sums are generated for a logic 0 carry-in and a logic 1 carry-in. Subsequently, a sum is selected from the plurality of conditional sums to form a first portion of an effective address from the logical address components in a first stage and a second portion of the effective address in a second stage. In one embodiment, a fully dynamic high-performance sparse tree adder circuit that generates one in four carries, is used to form an address generation circuit, in accordance with one embodiment. Other embodiments are described and claimed.
