    摘要： A memory circuit includes a word line, a data storage circuit including one or more memory cells or sub-cells, and an inverter coupled between the word line and the N memory cells. The inverter inverts a word-line signal input into a read port of the cells or sub-cells. Because the word-line inverter is local to each cell or sub-cell, DC offset is substantially reduced which translates into a reduction in leakage current.

    摘要： A register file includes a multi-level multiplexer output circuit coupled to a global bit trace and keeper circuitry coupled to said global bit trace and a driving signal trace. The register file also has decoder circuitry coupled to said keeper circuitry to selectively decouple the driving signal trace from said global bit trace.

    摘要： Disclosed is a system and device and related methods for data manipulation, especially for SIMD operations such as permute, shift, and rotate. An apparatus includes a permute section that repositions data on sub-word boundaries and a shift section that repositions the data distances smaller than the sub-word width. The sub-word width is configurable and selectable, and the permute section and shift section may operate on different boundary widths. In a first stage, the permute section repositions the data at the nearest sub-word boundary and, in a second stage, the shift section repositions the data to its final desired position. The shift section includes multi-stages set in a logarithmic cascade relationship. Additionally, each shifter within each of the multi-stages is highly connected, allowing fast and precise data movements.

    摘要： A logic circuit performs an internal level conversion function by driving portions of the circuit with different supply voltages. In one embodiment, first and second stage storage circuits are driven with different supply voltages. In another embodiment, first and second stage storage circuits are driven with a first supply voltage and an inverter coupled to the first stage storage circuit is driven with a second supply voltage. In either case, data transfer into the storage circuits may be controlled by different states of a clock signal. The logic circuit may be a flip-flop circuit, a latch circuit, or another type of circuit.
