The following figure presents RARE.

�N users on the Internet can share m adaptive computing resource

�� that are interconnected via a high speed local bus.

�Each of m resources contain a host general purpose processor and Mi

�� hardware programmable (FPGA) coprocessors, where i = 1, 2, � m.

�In this scenario, the RARE system will manage which user gains access to

�� a given adaptive computing resource at a given time.

�Hence, it appears that each user has access to a single low cost adaptive

�� computer with processing power that can approach that of a supercomputer.

�Our current RC system utilizes an FPGA

� coprocessor board with five user

� programmable PEs.

�Each PE includes a Xilinx 4044 FPGA

� containing 1600 CLBs or the equivalent

� of up to 80K logic gates.

�Total CLBs / equivalent logic gates

� available (8000/400K)
