  • Patent number: 11552646
    Abstract: A time-interleaved analog to digital converter (TI-ADC) includes a first sub-ADC configured to sample and convert an input analog signal to generate a first digital signal and a second sub-ADC configured to sample and convert said input analog signal to generate a second digital signal. Sampling by the second sub-ADC occurs with a time skew mismatch. A multiplexor interleaves the first and second digital signals to generate a third digital signal. A time skew mismatch error determination circuit processes the first and second digital signals to generate a time error corresponding to the time skew mismatch. A slope value of said third digital signal is determined and multiplied by the time error to generate a signal error. The signal error is summed with the third digital signal to generate a digital output signal which eliminates the error due to the time skew mismatch. This correction is performed in real time.

  • Publication number: 20230004354
    Abstract: A memory array arranged in multiple columns and rows. Computation circuits that each calculate a computation value from cell values in a corresponding column. A column multiplexer cycles through multiple data lines that each corresponds to a computation circuit. Cluster cycle management circuitry determines a number of multiplexer cycles based on a number of columns storing data of a compute cluster. A sensing circuit obtains the computation values from the computation circuits via the column multiplexer as the column multiplexer cycles through the data lines. The sensing circuit combines the obtained computation values over the determined number of multiplexer cycles. A first clock may initiate the multiplexer to cycle through its data lines for the determined number of multiplexer cycles, and a second clock may initiate each individual cycle. The multiplexer or additional circuitry may be utilized to modify the order in which data is written to the columns.

  • Publication number: 20220414420
    Abstract: Data structure and microcontroller architecture performing binary multiply-accumulate operations using multiple partial copies of weights. Destination-register location, source-register location, and weight-register location are received. Using the weight-register location, a sub-set of the weight bits is copied a select number of times based on a filter index value that is received. Each copy of the sub-set of weights is executed in parallel. Using the source-register location, a sub-set of the input bits is selected based on the size of the sub-set of weights, wherein the sub-set of input bits is shifted one bit from a previous sub-set of input bits. XOR operation is performed on each corresponding bit in the copy of the sub-set of weights with each corresponding bit in the selected sub-set of input bits. In a corresponding destination sub-location, output of each XOR operation is aggregated with each other and with current value of the corresponding destination sub-location.

  • Patent number: 11521697
    Abstract: A row decoder located on one side of a memory array selectively drives word lines in response to a row address. A word line fault detection circuit located on an opposite side of the first memory array operates to detect an open word line fault between the opposed sides of the memory array. The word line fault detection circuit includes a first clamp circuit that operates to clamp the word lines to ground. An encoder circuit encodes signals on the word lines to generate an encoded address. The encoded address is compared to the row address by a comparator circuit which sets an error flag indicating the open word line fault has been detected if the encoded address does not match the row address.

  • Patent number: 11522446
    Abstract: The charge transfer transistors of a positive or negative charge pump are biased at their gate terminals with a control voltage that provides for an higher level of gate-to-source voltage in order to reduce switch resistance in passing a boosted (positive or negative) voltage to a voltage output of the charge pump. This control voltage is generated using a bootstrapping circuit whose polarity of operation (i.e., negative or positive) is opposite to a polarity (i.e., positive or negative) of the charge pump.
