    Abstract: In one embodiment, the present invention includes a processor having multiple execution units, at least one of which includes a circuit having a multiply-accumulate (MAC) unit including multiple multipliers and adders, and to execute a user-level multiply-multiply-accumulate instruction to populate a destination storage with a plurality of elements each corresponding to an absolute value for a pixel of a pixel block. Other embodiments are described and claimed.

    Abstract: A computer processor includes a decoder for decoding machine instructions and an execution unit for executing those instructions. The decoder and the execution unit are capable of decoding and executing vector instructions that include one or more format conversion indicators. For instance, the processor may be capable of executing a vector-load-convert-and-write (VLoadConWr) instruction that provides for loading data from memory to a vector register. The VLoadConWr instruction may include a format conversion indicator to indicate that the data from memory should be converted from a first format to a second format before the data is loaded into the vector register. Other embodiments are described and claimed.
