Abstract
Instructions for a processing unit are stored in a number of memory banks, successive instructions being stored in successive, different memory banks. Whenever execution of an instruction is started, the reading of one instruction which will be executed more than one instruction cycle later is also started. Consequently, a plurality of instructions are being read in parallel from different memory banks. After the reading of an instruction, and before starting the execution of the instruction, the instruction passes through a pipeline in which the processing device detects whether the relevant instruction is a branch instruction. If this is so, the processing unit starts the reading in parallel of a number of instructions as from a branch target instruction. If it appears at a later stage that the branch is taken, said number of instructions is loaded into the pipeline in parallel.
