Frequent Data Value Compression for Graphics Processing Units

One or more non-transitory computer readable media storing instructions to perform a sequence comprising:

• using a unique code to encode a frequently recurring data value in a cacheline in a graphics processor;
• in response to detecting a frequently recurring data value, writing the unique code, instead of writing the frequently recurring value;
• upon identifying said unique code during a cacheline read, substituting for the code, the frequently recurring data value represented by the code;
• providing a first unique code to indicate at least one common data pattern for an entire cacheline;
• providing a second unique code to indicate at least one repeating data pattern for less than an entire cacheline;
• and
• providing as part of said second unique code an offset into the cacheline and a length of said repeating data pattern within the cacheline.
