Abstract
A microprocessor system comprises a computational array and a vector computational unit. The computational array includes a plurality of computation units. The vector computational unit is in communication with the computational array and includes a plurality of processing elements. The processing elements are configured to receive output data elements from the computational array and process in parallel the received output data elements.
Claims20
A microprocessor system, comprising:
- a computational array including computation units grouped into lanes;
- and
- a vector computational unit coupled to the computational array, the vector computational unit comprising:
- processing elements coupled to respective ones of the computation units, wherein the vector computational unit is configured to process information received as output from the lanes to form a processing result, wherein the lanes individually output output portions which form the information;
- and
- registers configured to individually store a same subset of a respective one of the individually output output portions.

A method implemented by a microprocessor system, the method comprising:
- receiving a single processor instruction for a vector computational unit, wherein the vector computational unit is coupled to a computational array and includes processing elements;
- receiving information from the computational array, wherein the computational array includes computation units grouped into lanes, the processing elements couple to respective ones of the computation units, and wherein the lanes individually output output portions which form the received information;
- and
- processing the information in parallel to form a processing result, wherein the vector computational unit includes registers configured to individually store a same subset of a respective one of the individually output output portions.
