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.

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.
