Operating System Concepts for Reconfigurable Computing: Review and Survey

Table 1

Operating systems for reconfigurable computing and their implemented OS aspects.

	Architecture		Application abstraction	Scheduling				Communication/synchronization	Example/benchmark applications	Note
	Reconfigurable area style	Interconnection		Schedule creation	hw-sw-interchangeable	Preemption	Real time focus
OS4RS (2003)	Islands	NoC	Task	Run-time	x	Check-pointing	x	NoC-based
HThreads (2005)	Static islands	Bus	PThread	Design time	—	—	x	Memory mapped
BORPH (2007)	Islands (FPGA)	P2P	Unix-process	Run-time	x	—	—	Message passing (OS kernel)	Signal and video processing	Linux extension extends executable format
ReconOS (2007)	Islands	Bus	Delegated PThread	Run-time	—	x	x	x	Video object tracking	Linux support
CAP-OS (2010)	Islands	NoC	Task	Run-time	x	—	x	NoC-based	Image processing
R3TOS (2010)	Grid	NoC	PThread	Run-time	—	—	x	NoC-based	SDR, JPEG-compression	Focus on reliability
FUSE (2011)	Islands	Bus	PThread	Run-time	—	—	—	Device driver mechanisms	Image processing, encryption	Loadable kernel modules (no need for a standard HW-IF)
SPREAD (2012)	Islands	Bus + P2P	Delegated PThread	Run-time	x	x	—	Bus based + P2P	De-/encryption
RTSM (2015)	Islands (inhomogeneous)	Bus	Delegated PThread	Run-time	x	x	x	Bus based, Vivado HLS IF	Image processing
