Abstract: Methods and apparatus relating to techniques for avoiding cache lookup for cold cache. In an example, an apparatus comprises logic, at least partially comprising hardware logic, to receive data for a current write operation to a memory, determine a number of bits in the received data for the current write operation to the memory which have changed from a previous write operation to the memory and in response to a determination that the number of bits in the received data for the current write operation to the memory which have changed from a previous write operation to the memory exceeds a threshold, to toggle a plurality of bits in the data for the current write operation to create an encoded data set and set an indicator bit to a value which indicates that the plurality of bits have been toggled. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to techniques for avoiding cache lookup for cold cache. In an example, an apparatus comprises logic, at least partially comprising hardware logic, to receive metadata from an application, wherein the meta data indicates one or more processing operations which can accommodate a predetermined level of bit errors in read operations from memory, determine, from the metadata, pixel data for which error correction code bypass is acceptable, and generate one or more error correction code bypass hints for subsequent cache access to the pixel data for which error correction code bypass is acceptable, and transmit the one or more error correction code bypass hints to a graphics processing pipeline. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to techniques for avoiding cache lookup for cold cache. In an example, an apparatus comprises logic, at least partially comprising hardware logic, to receive, in a read/modify/write (RMW) pipeline, a cache access request from a requestor, wherein the cache request comprises a cache set identifier associated with requested data in the cache set, determine whether the cache set associated with the cache set identifier is in an inaccessible invalid state, and in response to a determination that the cache set is in an inaccessible state or an invalid state, to terminate the cache access request. Other embodiments are also disclosed and claimed.
