摘要： Provided is a low power consuming mixed mode amplifier. The power amplifier includes: a low output amplifier circuit generating a power amplified result having high efficiency in a low output mode the most frequently used; a high output amplifier circuit generating an amplified result of high linearity in a high output mode of a region consuming the most power; an amplifier controller selectively activating the low and high output amplifier circuits according to a power level of an input signal. The high and low output amplifier circuits have a predetermined gain difference.

摘要： Disclosed herein is an apparatus and method for offloading parallel computation tasks. The apparatus inserts requests to execute multiple parallel thread groups into at least one parallel thread group queues, wherein when a preset order of priority exists the requests to execute is inserted into the at least one parallel thread group queues according to the preset order of priority, executes parallel threads of the parallel thread groups using a parallel thread group execution request entry extracted from the parallel thread group queue according to the order of priority, inserts an execution result into an execution result queue when execution of the parallel threads according to an execution sequence scheduled in execution startup routine code is terminated, and checks the execution termination state of the parallel thread groups by checking the execution result queue.
