摘要： A domino logic circuit and method comprise at least two series-connected domino logic stages with each domino logic stage comprising a dynamic stage and a static stage. A variable virtual ground of the first domino logic's static stage is switched to a voltage level below a circuit ground level when a received clock signal and a second domino logic stage's dynamic output are both high, indicating the second domino logic circuit stage is in the evaluation phase.

摘要： A signal driver circuit uses a single power supply to provide differential low voltage swing signals for use in an integrated circuit. The driver reduces interconnect voltage swing and power consumption, while improving the speed performance of the interconnect. The driver includes series coupled drive transistors to provide differential signals on integrated circuit interconnects. The driver circuit can include circuitry to place the interconnects in a tri-state condition to allow for shared interconnects. An integrated circuit, such as a processor, includes first and second differential interconnects, a receiver circuit connected to the first and second differential interconnects for detecting a differential voltage provided thereon, and a driver circuit connected to the first and second differential interconnects for providing the differential voltage.

摘要： A different set of polynomials may be selected for encryption and decryption accelerators. That is, different sets of polynomials are used for encryption and decryption, each set being chosen to use less area and deliver more power for a memory encryption engine. This is advantageous in some embodiments since memory read operations are typically more critical and latency sensitive than memory writes.

摘要： Methods and systems to implement voltage level shifting with interim-voltage-controlled contention-interruption. A voltage level shifter (VLS) may include voltage level shift circuitry to level shift an input logical state from an input voltage swing to an output voltage swing. The VLS may include contention circuitry, a contention interrupter, and an interrupt controller to generate a contention-interrupt control having an interim voltage swing. A lower limit of the interim voltage swing may correspond to a lower limit of the output voltage swing. An upper limit of the interim voltage swing may correspond to an upper limit of the input voltage swing. The VLS may be implemented to level shift true and complimentary logical states, such as with cascode voltage switch logic (CVSL). The interim-voltage-controlled contention interrupter may help to maintain voltages within process-based voltage reliability limits of the contention interrupter, with relatively little delay, and relatively little power and area consumption.

摘要： A merged datapath for PopCount and BitScan is described. A hardware circuit includes a compressor tree utilized for a PopCount function, which is reused by a BitScan function (e.g., bit scan forward (BSF) or bit scan reverse (BSR)). Selector logic enables the compressor tree to operate on an input word for the PopCount or BitScan operation, based on a microprocessor instruction. The input word is encoded if a BitScan operation is selected. The compressor tree receives the input word, operates on the bits as though all bits have same level of significance (e.g., for an N-bit input word, the input word is treated as N one-bit inputs). The result of the compressor tree circuit is a binary value representing a number related to the operation performed (the number of set bits for PopCount, or the bit position of the first set bit encountered by scanning the input word).

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.
