    摘要: A method and system for manipulating data in a state holding elements array. Process data is moved through the state holding elements array by a process controller. A separate scan controller scans data out of the state holding elements array by scanning data out of a group of cascaded latches where there are insufficient extra state holding elements in the group to enable normal scan. A multiplicity of local scan clocks are utilized to shift selected amounts of data only when a next state holding element in the group has been made available by clearing the contents of that next state holding element. In this way, any given latch, for the purpose of scan, is not a dedicated master or slave latch, but can act as either. This invention also addresses a circuit for the creation of the multiplicity of local clocks from a conventional LSSD clock source.

    摘要: A dynamic logical circuit having a pre-charge element separately controlled by a voltage-asymmetric clock controlled provides increased noise immunity in dynamic digital circuits. By clocking the pre-charge element with a signal having a reduced swing in the voltage direction that turns off the pre-charge element, the pre-charge element provides a small current that prevents the dynamic summing node of a gate from erroneously evaluating due to noise, and eliminates the need for a keeper device. Providing the reduced-swing asymmetric clock as a separate signal prevents performance degradation in the rest of the circuit. Specifically, the foot devices in the dynamic portion of the circuit are controlled with the full swing clock so that evaluation is not compromised by noise or slowed. Foot and pull-up devices in any static portion of the circuit are also controlled with the full-swing clock so that switching speed and leakage immunity are not affected.

    摘要: An apparatus for increasing addressability of registers within a processor is disclosed. The apparatus includes a set of apparent registers and a set of real registers. The total number of real registers is substantially higher than the total number of apparent registers such that only a subset of the real registers is referenced by all of the apparent registers at any given time. Any one of the real registers can be designated by an instruction via one of the apparent registers. Any one of the actual registers can also be directly designated by an instruction.

    摘要: A facility is provided for managing register maps for map-based indirect register file access within a processor. The management facility includes a register mapping including a set of maps, each map of the set of maps having a plurality of map registers. A set of actual registers is indirectly accessed by the processor via map entries of the set of maps. The number of actual registers in the set of actual registers is greater than the number of map entries in the set of maps, and the map entries of the set of maps reference only a subset of the set of actual registers at any given time. The facility includes managing updates to multiple entries of the set of maps of the register mapping by updating multiple map entries of at least one map of the set of maps responsive to executing a single update instruction.

    摘要: Methods and arrangements to adjust a duty cycle of a clock signal are disclosed. Embodiments may include a duty cycle controller to adjust the duty cycle of the clock signal based upon a delay signal and an input clock signal. A duty cycle detector may determine signals with frequencies based upon the duty cycle of the output signal and a correction module may compare the frequencies of the detector signals to generate the delay signal. In some embodiments, once the duty cycle of the output clock signal reaches the desired duty cycle such as fifty percent, the correction module may be turned off.
