Abstract:
A method and apparatus for including in a processor instructions for performing multiply-add operations on packed data. In one embodiment, a processor is coupled to a memory. The memory has stored therein a first packed data and a second packed data. The processor performs operations on data elements in said first packed data and said second packed data to generate a third packed data in response to receiving an instruction. At least two of the data elements in this third packed data storing the result of performing multiply-add operations on data elements in the first and second packed data.
Abstract:
In one embodiment, a system comprises a portable computing device comprising a first graphics controller and a first communication interface, and a turbo station comprising a second communication interface to manage communication with the portable computing device, and at least one auxiliary computing component comprising a multi-core graphics engine coupled to the communication interface and configured to process cooperatively with the first graphics controller in the portable computing device.
Abstract:
An apparatus and method for efficient filtering and convolution of content data are described. The method includes organizing, in response to executing a data shuffle instruction, a selected portion of data within a destination data storage device. The portion of data is organized according to an arrangement of coefficients within a coefficient data storage device. Once organized, a plurality of summed-product pairs are generated in response to executing a multiply-accumulate instruction. The plurality of product pairs are formed by multiplying data within the destination data storage device and coefficients within the coefficient data storage device. Once generated, adjacent summed-product pairs are added in response to executing an adjacent-add instruction. The adjacent summed-product pairs are added within the destination data storage device to form one or more data processing operation results. Once the one or more data processing operation results are formed, the results are stored within a memory device.
