In one embodiment, a digital signal processor (DSP) processes both n-bit data and (n/2)-bit data. The DSP includes multiple processing paths. A first processing path processes n-bit data. A second processing path is processes (n/2)-bit data. The multiple processing paths may be established using multiple components or may share components. When the processing paths share components, only one of the processing paths may be used at a time.

DSP execution unit for efficient alternate modes for processing multiple data sizes

An integrated circuit which has two separate paths for two different data widths. The first processing path processes data up to n bits in a n multiplier. A second path operates in parallel with the first path, and includes smaller units which process data up to n 2 bits. The two paths can operate in parallel, but since the two paths have different data widths, they can more effectively operate with the different data sizes.

Selectively processing different size data in multiplier and ALU paths in parallel

A processor core suitable for use with a wide variety of instruction fetch units. The processor core contains a plurality of pipe stages including an instruction pointer generation stage and a decode stage. The core bundles all control necessary for downstream pipeline operation with an instruction address in a first stage. The bundle is transmitted outside the core to the instruction fetch unit. The instruction fetch unit fetches the instruction and adds it to the bundle, before forwarding the bundle as modified back within the core and down the pipeline. In this way, an external pipe stage is introduced providing a connection between discontinuous pipe stages in the core. Additionally, by bundling the control signals and address information in a single bundle that traverses the external pipe stage as a group, synchronization concerns are reduced or eliminated.
