Latest Patents

Schwinn's latest patents include "Dynamic merging of pipeline stages in an execution pipeline to reduce power consumption." This innovation involves a pipelined execution unit that incorporates low power modes by dynamically merging pipeline stages. By setting intermediate latches to a transparent state, the output of one pipeline stage can be passed to the next during the same clock cycle, effectively allowing both stages to perform steps for the same instruction. This method reduces power consumption by lowering the clock frequency and operating voltage, while maintaining performance.

Another significant patent is "Structural power reduction in multithreaded processor." This invention utilizes multiple execution units with varying power and performance characteristics within a multithreaded processor core. It selectively routes instructions based on their performance requirements, directing high-performance tasks to more capable execution units and low-performance tasks to reduced power units. This approach minimizes power consumption and heat generation during processing.
