Safety architecture boosts automotive GPU for chiplets
By Nick Flaherty, eeNews Europe (September 17, 2024)
Imagination Technologies has launched its latest automotive multicore GPU IP for chiplet designs with a new safety architecture.
The DXS is a scalable and flexible GPU IP designed by Imagination to process graphics and compute workloads in cockpit, infotainment and advanced driver assistance systems.
The design eliminates the overhead of achieving ASIL-B functional safety using a Distributed Safety Mechanisms that has a near-zero impact on GPU performance and minimal area cost, estimated at just 10%.
It does this by taking advantage of the inherent parallelism of today’s processors and the fact that no thread is ever fully utilised. A patented mechanism combines these threads into pairs and injects safety tests in idle moments to identify faults within the timeframe set by the ASIL standard.
