摘要： In general, in one aspect, the disclosure describes a multiplier that includes a set of multiple multipliers configured in parallel where the set of multiple multipliers have access to a first operand and a second operand to multiply, the first operand having multiple segments and the second operand having multiple segments. The multiplier also includes logic to repeatedly supply a single segment of the second operand to each multiplier of the set of multiple multipliers and to supply multiple respective segments of the first operand to the respective ones of the set of multiple multipliers until each segment of the second operand has been supplied with each segment of the first operand. The logic shifts the output of different ones of the set of multiple multipliers based, at least in part, on the position of the respective segments within the first operand. The multiplier also includes an accumulator coupled to the logic.

摘要： Vector instructions for performing ZUC stream cipher operations are received and executed by the execution circuitry of a processor. The execution circuitry receives a first vector instruction to perform an update to a liner feedback shift register (LFSR), and receives a second vector instruction to perform an update to a state of a finite state machine (FSM), where the FSM receives inputs from re-ordered bits of the LFSR. The execution circuitry executes the first vector instruction and the second vector instruction in a single-instruction multiple data (SIMD) pipeline.
