摘要:
A processor has multiple cores with each core having an associated function to support processor operations. The functions performed by the cores are selectively altered to improve processor operations by balancing the resources applied for each function. For example, each core comprises a field programmable array that is selectively and dynamically programmed to perform a function, such as a floating point function or a fixed point function, based on the number of operations that use each function. As another example, a processor is built with a greater number of cores than can be simultaneously powered, each core associated with a function, so that cores having functions with lower utilization are selectively powered down.
