Abstract
A processing system includes an arithmetic logic unit (ALU) sub-system that allows data associated with a prior instruction to be preserved for use with a next instruction or subsequent instruction without having to reload the value using an intermediate register. The ALU sub-system includes a pair of ALUs communicatively cross-coupled with a pair of accumulators. The processing system also includes a data selector coupled to the ALU sub-system for use with memory contention prediction. The data selector includes a constant generator that controls storage of data associated with a previous instruction in a bypass element, and a selector to choose between data from a databus element and data stored in the bypass element.
