|6202163||Data processing circuit with gating of clocking signals to various elements of the circuit|
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 disa...
|6145076||System for executing nested software loops with tracking of loop nesting level|
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 o...
|6038675||Data processing circuit|
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 clock...
