Abstract

A programmable logic integrated circuit device ('PLD') includes programmable logic and a dedicated (i.e., at least partly hard-wired) processor object (or at least a high-functionality functional unit) for performing or at least helping to perform tasks that it is unduly inefficient to implement in the more general-purpose programmable logic and/or that, if implemented in the programmable logic, would operate unacceptably or at least undesirably slowly. The processor object includes an operating portion and a program sequencer that retrieves or at least helps to retrieve instructions for controlling or at least partly controlling the operating portion. The processor object may also include an address generator and/or a multi-ported register file for generating or at least helping to generate addresses of data on which the operating portion is to operate and/or destinations of data output by the operating portions. Examples of typical operating portions include multiplier-accumulators, arithmetic logic units, barrel shifters, and DSP circuitry of these or other kinds. The PLD may be provided with the capability to allow programs to be written for the device using local or 'relative' addresses, and to automatically convert theses addresses to actual or 'absolute' addresses when the programs are actually performed by the device.
