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 ...

A data cache configured to perform store accesses in a single clock cycle is provided. The data cache speculatively stores data within a predicted way of the cache after capturing the data currently being stored in that predicted way. During a subsequent clock cycle, the cache hit information for the store access validates the way prediction. If the way prediction is correct, then the store is com...

A way prediction structure is provided which predicts a way of an associative cache in which an access will hit, and causes the data bytes from the predicted way to be conveyed as the output of the cache. The typical tag comparisons to the request address are bypassed for data byte selection, causing the access time of the associative cache to be substantially the access time of the direct-mapped ...

An eight-bit RISC based microcontroller (10) includes an eight-bit register file having a dedicated arithmetic logic unit ALU (ALU-2), in addition to general purpose eight-bit ALU (ALU-1). The register file further includes means for combining a pair of registers (100) to provide a logical sixteen-bit register for directing addressing. The dedicated ALU (ALU-2) is a sixteen-bit ALU which provides ...
