    摘要: Write-through-read (WTR) comparator circuits and related WTR processes and memory systems are disclosed. The WTR comparator circuits can be configured to perform WTR functions for a multiple port file having one or more read and write ports. One or more WTR comparators in the WTR comparator circuit are configured to compare a read index into a file with a write index corresponding to a write-back stage selected write port among a plurality of write ports that can write data to the entry in the file. The WTR comparators then generate a WTR comparator output indicating whether the write index matches the read index to control a WTR function. In this manner, the WTR comparator circuit can employ less WTR comparators than the number of read and write port combinations. Providing less WTR comparators can reduce power consumption, cost, and area required on a semiconductor die for the WTR comparator circuit.

    摘要: Static-based comparators and methods for comparing data are disclosed. The static-based comparator is configured to selectively switch at least one comparator output in response to a comparison of corresponding data with compare data, and a validity indicator for the data. If the validity indicator indicates valid data, the static-based comparator switches to drive the comparator output indicating either a match or mismatch between corresponding compared data. If the validity indicator indicates invalid data, the static-based comparator provides a mismatch on the comparator output without switching the static-based comparator regardless of whether or not the data matches the compare data. In this manner, the static-based comparator does not dissipate power switching the comparator output for data marked invalid. The static-based comparator can be employed in content addressable memories (CAMs) for comparing one or more bits of tag data to corresponding bit(s) of compare data.

    摘要: Systems and methods for bi-modal and fine grained power delivery to an integrated circuit comprising functional blocks. A first power source is coupled to a functional block of the integrated circuit for supporting a first operating mode of the functional block. A second power source is coupled to the functional block for supporting a second operating mode of the functional block. The first and second operating modes can be high and low frequency modes respectively. The second power source can be derived from the first power source using on-die regulators or provided independently. A desired average throughput of the functional block can be achieved by controlling duty cycles of the first and second power sources.
