摘要： Embodiments of the invention relate to increased energy efficiency and conservation by reducing and increasing an amount of cache available for use by a processor, and an amount of power supplied to the cache and to the processor, based on the amount of cache actually being used by the processor to process data. For example, a power control unit (PCU) may monitor a last level cache (LLC) to identify if the size or amount of the cache being used by a processor to process data and to determine heuristics based on that amount. Based on the monitored amount of cache being used and the heuristics, the PCU causes a corresponding decrease or increase in an amount of the cache available for use by the processor, and a corresponding decrease or increase in an amount of power supplied to the cache and to the processor.

摘要： Various embodiments may be disclosed that may share a ROM pull down logic circuit among multiple ports of a processing core. The processing core may include an execution unit (EU) having an array of read only memory (ROM) pull down logic storing math functions. The ROM pull down logic circuit may implement single instruction, multiple data (SIMD) operations. The ROM pull down logic circuit may be operatively coupled with each of the multiple ports in a multi-port function sharing arrangement. Sharing the ROM pull down logic circuit reduces the need to duplicate logic and may result in a savings of chip area as well as a savings of power.

摘要： A high-speed memory management technique that minimizes clobber in sequentially accessed memory, including but not limited to, for example, a trace cache. The method includes selecting a victim set from a sequentially accessed memory; selecting a victim way for the selected victim set; reading a next way pointer from a trace line of a trace currently stored in the selected victim way, if the selected victim way has the next way pointer; and writing a next line of the new trace into the selected victim way over the trace line of the currently stored trace. The method also includes forcing a replacement algorithm of next set to select a victim way of the next set using the next way pointer, if the trace line of the currently stored trace is not an active trace tail line.
