Cache Drop Feature To Increase Memory Bandwidth And Save Power

View page
US Patent:
20180349291, Dec 6, 2018
Filed:
May 31, 2017
Appl. No.:
15/610008
Inventors:
- Cupertino CA, US
Kenneth C. Dyke - Los Altos CA, US
Karthik Ramani - San Jose CA, US
Winnie W. Yeung - San Jose CA, US
Anthony P. DeLaurier - Los Altos CA, US
Luc R. Semeria - Palo Alto CA, US
David A. Gotwalt - Winter Springs FL, US
Srinivasa Rangan Sridharan - San Jose CA, US
Muditha Kanchana - San Jose CA, US
International Classification:
G06F 12/123
G06F 12/0808
G06F 12/0815
G06F 12/0804
Abstract:
Systems, apparatuses, and methods for efficiently allocating data in a cache are described. In various embodiments, a processor decodes an indication in a software application identifying a temporal data set. The data set is flagged with a data set identifier (DSID) indicating temporal data to drop after consumption. When the data set is allocated in a cache, the data set is stored with a non-replaceable attribute to prevent a cache replacement policy from evicting the data set before it is dropped. A drop command with an indication of the DSID of the data set is later issued after the data set is read (consumed). A copy of the data set is not written back to the lower-level memory although the data set is removed from the cache. An interrupt is generated to notify firmware or other software of the completion of the drop command.

US Patent:
20180181491, Jun 28, 2018
Filed:
Dec 22, 2016
Appl. No.:
15/389153
Inventors:
- Cupertino CA, US
Luc R. Semeria - Palo Alto CA, US
Gokhan Avkarogullari - Cupertino CA, US
David A. Gotwalt - Winter Springs FL, US
Robert S. Hartog - Windermere FL, US
Michael J. Swift - San Francisco CA, US
International Classification:
G06F 12/0891
G06F 12/0895
Abstract:
Techniques are disclosed relating to flushing cache lines. In some embodiments, a graphics processing unit includes a cache and one or more storage elements configured to store a plurality of command buffers that include instructions executable to manipulate data stored in the cache. In some embodiments, ones of the cache lines in the cache are configured to store data to be operated on by instructions in the command buffers and a first tag portion that identifies a command buffer that has stored data in the cache line. In some embodiments, the graphics processing unit is configured to receive a request to flush cache lines that store data of a particular command buffer, and to flush ones of the cache lines having first tag portions indicating the particular command buffer as having data stored in the cache lines while maintaining data stored in other ones of the cache lines as valid.
