An example FGPA CM - Transmogrifier-2
Uses Altera Flex10K100 FPGAs (each FPGA = 100K gates). Uses Crossbar switches and has 10Mbytes of RAM
Logical Network looks like a binary tree - 32 FPGAs max
Physical implementation is 16 boards connected by a backplane (each board contains 2 FPGA + SRAM and crossbar switches)
Tested applications to date have been video applications
