Patents by Inventor Alagappan Valliappan

Alagappan Valliappan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240152575
    Abstract: Disclosed herein includes a system, a method, and a device for processing and converting data using matrix operations. Circuitry can partition an input of a first data format across a plurality of lookup tables each residing in a respective memory. The circuitry can access weight information from a load store memory, and the partitioned input on a per column basis from the plurality of lookup tables. The circuitry can perform a number of multiply-accumulate (MAC) operations per cycle between the weight information from the load store memory and the partitioned input read on a per column basis from the plurality of lookup tables. The number of MAC operations performed per cycle can correspond to a total number of columns of the plurality of lookup tables. The circuitry can generate, responsive to the MAC operations on the partitioned input, a plurality of outputs in a second data format.

  • Patent number: 11429394
    Abstract: Disclosed herein includes improving computational efficiency of multiply-accumulate (MAC) operation. In one aspect, a computing device identifies, a first vector including non-zero elements of a base matrix, and a second vector indicating a location of each of the non-zero elements of the base matrix. In one aspect, the device determines a first element and a second element of the first vector. In one aspect, the device determines a third element and a fourth element of the second vector. In one aspect, the device determines i) a fifth element of an input vector according to the third element of the second vector, and ii) a sixth element of the input vector according to the fourth element of the second vector. In one aspect, the device causes a MAC circuitry to perform a dot product according to the first element, the second element, the fifth element, and the sixth element.
