Abstract: In an embodiment, a processor includes a decode logic to receive and decode a first memory access instruction to store data in a cache memory with a replacement state indicator of a first level, and to send the decoded first memory access instruction to a control logic. In turn, the control logic is to store the data in a first way of a first set of the cache memory and to store the replacement state indicator of the first level in a metadata field of the first way responsive to the decoded first memory access instruction. Other embodiments are described and claimed.

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.
