    摘要: Embodiments of the invention are generally directed to systems, methods, and apparatuses for inverter based return-to-zero (RZ)+non-RZ (NRZ) signaling. The interface circuit contains multiple ganged drivers (some or all of them are turned on at one point of time) and edge detection circuitry (to configure/modulate edges of the input data signal). These two circuits together generate weighted return-to-zero (RZ)+non-RZ (NRZ) signal.

    摘要: A cache memory system uses multi-bit Error Correcting Code (ECC) with a low storage and complexity overhead. In an embodiment, error correction logic may include a first error correction logic to determine a number of errors in data that is stored in a cache line of a cache memory, and a second error correction logic to receive the data from the first error correction logic if the number of errors is determined to be greater than one and to perform error correction responsive to receipt of the data. The cache memory system can be operated at very low idle power, without dramatically increasing transition latency to and from an idle power state due to loss of state. Other embodiments are described and claimed.

    摘要: Embodiments of an invention for low overhead error-correcting-code protection for stored information are described are disclosed. In one embodiment, an apparatus includes a data storage structure, a first check value storage structure, a second check value storage structure, and check value generation hardware. The data storage structure is to store a plurality of first data values. The first check value storage structure is to store a plurality of first check values. The second check value storage structure is to store a plurality of second check values. The check value generation hardware is to generate the first check values and the second check values. The first check values provide a first level of error protection for the first data values and the second check values provide a second level of error protection for a plurality of second data values. Each of the plurality of first data value has a first data width, and each of the plurality of second data values has a second data width, the second data width being greater than the first data width. Each of the second data values is a concatenation of one of the first data values and at least another of the first data values.
