....faster switching between CFU configurations, reducing idle time while the system waits for the CFU set to be altered. The idea of multiple configuration stores in FPGAs was first published in [133] DeHon later based his Dynamically Programmable Gate Array (DPGA) architecture around this idea [39, 159] and did a study of the benefits of multiple configuration stores in various applications [38] An earlier use of multiple configuration stores in a di#erent context was described by Snyder [34] In [163] the architecture of a time multiplexed FPGA is proposed. Eight configurations of the FPGA are ....

....FPGAs As described in the Introduction, the time required to reconfigure a traditional FPGA is very high. To reduce the reconfiguration time, a device having more than one configuration context was proposed in [4] Several such multicontext FPGAs have been recently proposed [13] 11] 14] 8][3]. These devices have on chip RAM to store a number of configuration contexts, varying from 8 to 256. At any given time, one context governs the logic functionality and is referred to as the active context. Switching contexts takes 5 100 ns. This is several orders of magnitude faster than the time ....
