摘要： A full-rail digital-read CIM circuit enables a weighted read operation on a single row of a memory array. A weighted read operation captures a value of a weight stored in the single memory array row without having to rely on weighted row-access. Rather, using full-rail access and a weighted sampling capacitance network, the CIM circuit enables the weighted read operation even under process variation, noise and mismatch.

摘要： Techniques and mechanisms for performing in-memory computations with circuitry having a pipeline architecture. In an embodiment, various stages of a pipeline each include a respective input interface and a respective output interface, distinct from said input interface, to couple to different respective circuitry. These stages each further include a respective array of memory cells and circuitry to perform operations based on data stored by said array. A result of one such in-memory computation may be communicated from one pipeline stage to a respective next pipeline stage for use in further in-memory computations. Control circuitry, interconnect circuitry, configuration circuitry or other logic of the pipeline precludes operation of the pipeline as a monolithic, general-purpose memory device. In other embodiments, stages of the pipeline each provide a different respective layer of a neural network.

The system may further include determination of whether a least-significant bit of product Z is 1, addition of a least-significant w bits of modulus M to the least-significant w bits of product Z if the least-significant bit of product Z is 1, multiplication of the least-significant bit of X and bits 2w-1:w of Y to generate bits 2w-1:w of product Z, and addition of bits 2w-1:w of modulus M to bits 2w-1:w of product Z if the least-significant bit of product Z is 1. Multiplying the least-significant bit of X and bits 2w-1:w of Y may occur at least partially contemporaneously with multiplying the least-significant bit of X and the least-significant w bits of Y, determining if the least-significant bit of product Z is 1, and adding the least-significant w bits of modulus M to the least-significant w bits of product Z if the least-significant bit of product Z is 1.

摘要： A Viterbi decoder includes an ACS unit that performs state metric updates for every symbol cycle. State metric updates involve adding the state metrics corresponding to a likely input symbol to the respective branch matrix, comparing the results of the additions to determine which is smaller, and selecting the smaller result for the next state metric. The ACS unit includes two parallel adders followed by a parallel comparator that generates a multiplexer-select signal. The outputs of the parallel adders are input into a multiplexer and the multiplexer-select signal is input into the multiplexer for a decision.

摘要： A variable keeper strength based process-compensated dynamic circuit and method provides a robust digital way to overcome the intrinsic parameter variation present in manufactured die. Using a process-compensated dynamic circuit, the wide robustness and delay distribution becomes narrower which improves performance without sacrificing worst-case robustness. The strength of the keeper is programmed depending on the amount of die leakage. The keeper will have an optimal strength for the best and worst case leakage, allowing better performance with improved worst-case robustness.
