Abstract: Example implementations described herein are directed to the generation of a specification for automatic power management of a network on chip and/or a system on chip. Such example implementations can include automatically generating a specification comprising at least one of a power domain, an always-on indicator, a voltage domain, a voltage level, and a clock frequency for each of one or more agents of a System on Chip (SoC) and a Network on Chip (NoC), the voltage domain indicative of power supply of the each agent, and the power domain indicative of one or more power switch rules applied to the each agent.

Abstract: A memory system includes an active storage circuit and at least one base storage circuit. The at least one base storage circuit is coupled to the active storage circuit though at least one pass gate, at least one driver and a bit line. The at least one pass gate and the at least one driver have a device size substantially similar to a device size of each one of the devices in the active storage circuit and the at least one base storage circuit. A method of swapping data between two storage circuits is also described.

Abstract: A method for modeling the power behavior of a pipelined processor has been developed. The method uses a power model integrated into a cycle accurate simulator. To create the power model, design blocks of the processor are divided into sub-blocks. Power modeling equations for each sub-block are developed by collaboration between the sub-block circuit designer and the simulator developer, using activity information relevant to the sub-block that is available in the simulator model. Each equation is calculated multiple times with different sets of power parameters to represent varying power conditions. Every simulation cycle, sub-block power is summed to generate full-chip power for multiple power conditions.

Abstract: A system and method for scheduling instructions that are executed in the microprocessor are provided. The microprocessor executes multiple instructions per cycle that may have dependencies on execution results of other instructions. A scoreboard is utilized to schedule instructions. The scoreboard indicates dependencies between instructions. The scoreboard also controls the indication of dependencies based on the issuance of old instructions. The scoreboard includes a register for each instruction. The register has elements each of which corresponds to one of other instructions. An element of the register for an instruction is set where the element corresponds to one of other instructions which the instruction depends on.

Each minor sense amplifier circuit has a minor sense input node, and a minor sense miss/match node. Each minor sense line is also coupled to at least two CAM cell miss/match nodes. A minor sense precharging device is coupled to each minor sense line. The minor sense precharging device selectively conducts current to precharge the minor sense lines to a first predetermined voltage. Each of the major sense amplifiers has a major sense input node, and a major sense miss/match node.
