    摘要: An improvement to an integrated circuit of a type having a test enable line for enabling an electrical test of the integrated circuit only when the test enable line is at a logical high value, and output lines that are only used during the electrical test of the integrated circuit, where the improvement is a switch circuit for disabling a state change in the output lines when the test enable line is at a logical low value. In this manner, the output lines do not switch during functional use of the integrated circuit, and cannot be aggressors on the data signals that are carried by the data lines that are used during the functional use of the integrated circuit. In addition, these non-switching output lines can act as guard traces that run between the data lines, further electrically isolating the data lines from one another. Further, because they do not switch during functional use of the integrated circuit, the overall power consumption of the integrated circuit is reduced.

    摘要: In one embodiment, a circuit has multiple flip-flops with gated clock inputs controlled by an enable signal, where the clock signal is gated in order to reduce power consumption by the circuit. The circuit has an error detection and correction (EDC) module that is active when the enable signal is low in order to detect and correct soft errors of the flip-flops. The EDC module generates and stores an error-correction code based on the data outputs of the flip-flops. The EDC module then compares the stored error-correction code to a presently generated error-correction code, where if they are not identical, then the EDC (a) determines (i) that a soft error has occurred and (ii) which flip-flop suffered the soft error and (b) flips a corresponding error-correction signal to provide a correct corresponding output signal while the enable signal is low.

    摘要: A method of placing a clock signal supply network in a design representation for an integrated circuit. The design representation may comprise a plurality of clockable circuit cells. The method may comprise identifying a first of the clockable circuit cells in the design representation. The method may further comprise identifying a second of the clockable circuit cells in the design representation. The second clockable circuit cell may have a clock timing dependent relation relative to the first clockable circuit cell. The method may further comprise configuring the clock signal supply network. The clock signal supply network may be configured to supply respective clock signals to the first and said second clockable circuit cells. The clock signal supply network may be configured to route the respective clock signals such that a timing difference between the respective clock signals is protected from process, voltage and temperature (PVT) influences.

    摘要: A data-processing system and method are disclosed, which include a cached processor for processing data, and a plurality of memory components that communicate with the cached processor. The cached processor is separated from the memory components such that the cached processor provides support for the memory components, thereby providing a diffused memory architecture with diffused memory capabilities. The memory components can constitute, for example, memory devices such as diffused memory, matrix memory, R-Cell memory components, and the like, depending on design considerations.
