    摘要: Embodiments of an invention for a compact, low power Advanced Encryption Standard circuit are disclosed. In one embodiment, an apparatus includes an encryption unit having a substitution box and an accumulator. The substitution box is to perform a substitution operation on one byte per clock cycle. The accumulator is to accumulate four bytes and perform a mix-column operation in four clock cycles. The encryption unit is implemented using optimum Galois Field polynomial arithmetic for minimum area.

    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: 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.
