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.

摘要: Disclosed herein is a router configured for priority-based routing. The router is configured to receive a plurality of packets, wherein each packet is assigned a priority value. The router includes an output circuit configured to select the packet with the highest priority value. The output circuit is configured to forward the priority value of the selected packet to a second router. The output circuit is configured to transfer the selected packet to the second router when the link between the first router and the second router is available.

摘要: For one disclosed embodiment, a converter converts 2N-bit data into an N-bit value indicating a number of bits in the data that have a predetermined logical value. The converter includes N comparators, each determining whether the number of bits in the data having the predetermined logical value exceeds a respective one of a plurality of reference values. The N-bit value is generated based on the outputs of the comparators. For another disclosed embodiment, a first delay element delays a signal based on a number of bits in a data value having a predetermined logical value, and a second delay element delays the signal based on a number of bits in a reference value having the predetermined logical value. A comparator then generates a bit value based on the delayed signals.
