METHOD AND SYSTEM FOR SCALABLE, RADIATION-TOLERANT, SPACE-RATED, HIGH INTEGRITY GRAPHICS PROCESSING UNIT

摘要

The provided scalable, radiation tolerant, high-integrity, space-rated Graphical Processing Unit (GPU) supports open interfaces and provides sufficient graphics performance for known display formats as well as as-yet-undefined, futuristic, display formats that may be updated on-mission without needing, for example, a host space vehicle to return to earth or a lunar site. The provided GPU further provides flexibility and dynamic scalability.

主权项

1. A method for implementing a graphics processing unit (GPU), comprising:
at a first GPU core:
receiving N input parallel graphic data sets (PGD), where N is a first number;dynamically creating a first configuration in which each of the N input PGD is coupled to a respective one of N graphics engines;dynamically (i) enabling P graphics engines, where P is a second number that is less than or equal to N, and (ii) disabling a remaining N−P graphics engines;at each of the P enabled graphics engines, processing PGD by(i) validating an associated input PGD, thereby generating a validated PGD;(ii) rasterizing the validated PGD, thereby creating a rasterized PGD, and(iii) synchronizing the rasterized PGD according to the first configuration, thereby creating a synch-adjusted PGD;merging the synch-adjusted PGD from each of the P graphics engines, thereby creating merged PGD; anddistributing, according to a first distribution, the merged PGD to a plurality of graphic sinks.
