  • Data processing circuit with gating of clocking signals to various elements of the circuit
    Patent number: 6202163
    Abstract: A data processing circuit (201) is shown having elements (315, 310) which operate in response to decoded instruction while receiving clocking signals. Instruction types are identified and clocking signals to at least one of the elements is enabled or disabled in dependence upon whether the element is required for the execution of the identified instruction type.

  • System for executing nested software loops with tracking of loop nesting level
    Patent number: 6145076
    Abstract: A data processing circuit is arranged to execute program instructions defining nested loops. A loop is defined in terms of a start address, an end address and a number of loop iterations. The processing circuit includes a program counter and a plurality of loop counting elements. Each of the loop counting elements includes a start address register, an end address register, a loop iteration register and means for comparing the value stored in the respective end address register with the output from the program counter.

  • Data processing circuit
    Patent number: 6038675
    Abstract: A data processing circuit includes a first set of processing elements and a second set of processing elements. A clock provides common clocking signals to the processing elements, however, the first set of elements are clocked by rising edges of the clocking signals and the second set of elements are clocked by falling edges of the clocking signals.

  • Method for writing a program to control processors using any instructions selected from original instructions and defining the instructions used as a new instruction set
    Patent number: 5964861
    Abstract: A method for designing a processor. The method utilises the full flexibility of an original instruction set in writing programs for operation of the processor the subset of instruction words used in writing the program are then used in defining the instruction decoder of the processor.
