Supporting access to accelerators on a programmable integrated circuit by multiple host processes

Abstract:

Supporting multiple clients on a single programmable integrated circuit (IC) can include implementing a first image within the programmable IC in response to a first request for processing to be performed by the programmable IC, wherein the request is from a first process executing in a host data processing system coupled to the programmable IC, receiving, using a processor of the host data processing system, a second request for processing to be performed on the programmable IC from a second and different process executing in the host data processing system while the programmable IC still implements the first image, comparing, using the processor, a second image specified by the second request to the first image, and, in response to determining that the second image matches the first image based on the comparing, granting, using the processor, the second request for processing to be performed by the programmable IC.
