Abstract
An apparatus and a method for pipeline control are provided. The apparatus includes a preload predictor, an arithmetic logic unit (ALU) and a data buffer. The preload predictor is configured to determine whether a load instruction conforms to at least one specific condition, to generate a preload determination result. The ALU is configured to perform arithmetic logic operations, and the data buffer is configured to provide data for being used by the ALU. When the preload determination result indicates that the load instruction conforms to the at least one specific condition, the data buffer fetches preload data from a cache memory according to information carried by the load instruction and stores the preload data in the data buffer, where the preload data is data requested by a subsequent load instruction.
