Virtualization of Computing Resources in RCS for Multi-task Stream Applications

The possibility for distribution of FPGA resources in the temporal domain for multi-modal & multi-task workloads conceptually allows virtualization of logic, communication and input/output resources similar to memory virtualization in advanced conventional computers (e.g. superscalar). This, in turn, can dramatically increase the cost-effectiveness of FPGA based reconfigurable computing systems (RCS). In the presented ¿proof-of-concept¿ research the following topics have been investigated, developed and tested: i) architecture of a platform to support the dynamic allocation of application specific virtual processors (ASVP), ii) mechanisms for run-time on-chip assembly of ASVP from virtual hardware components (VHC) and iii) mechanisms for run-time on-chip components (VHC) relocation in predetermined regions of the FPGA device. The above mechanisms have been implemented and tested on a specially developed platform: the multi-task adaptive reconfigurable system (MARS) platform. The actual application of MARS was prototyping a high-performance multi-mode stereo-vision system (200 fps) for the next generation of space-borne computing platforms.
