摘要： Techniques are disclosed for minimizing the effects of soft errors associated with memory devices that are individually accessible. By way of example, a method of organizing a column in a memory array of a memory device protected by an error correction code comprises the step of maximizing a distance of the error correction code by maximizing a physical distance between memory bits associated with a memory line within the column protected by the error correction code. Other soft error protection techniques may include use of a feed forward error correction code or use of a memory operation (e.g., read or write operation) suppress and retry approach.

摘要： Methods and apparatus for comparing two binary numbers with a power-of-two threshold are provided in accordance with the present invention. In one embodiment, a method for comparing two binary numbers with a power-of-two threshold includes the steps of generating new relations, namely, much_greater_than (ggi) and equal_to (nqi), based at least in part on generate (gt) and propagate (eq) signals created for each bit of the binary numbers to be compared, and applying recursion in order to reduce the set of input signals at successive recursive nodes by a predetermined number. By omitting a pre-addition operation, the present invention eliminates the use of exclusive-OR logic gates, thus significantly reducing system cost and delay.

摘要： A digital signal processing device for processing an input signal includes delay generation circuitry and processing circuitry. The delay generation circuitry receives the input signal and includes a plurality of delay stages operatively coupled together, each of the delay stages having a predetermined time delay associated therewith. The delay generation circuitry includes a zero delay signal path and at least one nonzero delay signal path associated therewith. The processing circuitry is operatively configured to: (i) define a first subset of signal paths through the delay generation circuitry, the first subset including the zero delay signal path, and at least a second subset of signal paths through the delay generation circuitry, the second subset including one or more nonzero delay signal paths; (ii) remove an idle delay from all signal paths in the second subset, such that a shortest nonzero delay signal path in the second subset becomes a zero delay signal path; and (iii) incorporate the idle delay with the processing circuitry.
