10. MultiCore: Explain what to do, to the driver Caches, instruction buffers, and predictors needed ManyCore: Explain what to do, to many sub-drivers Reduced caches and instruction buffers needed DataFlow: No caches, instruction buffers, or predictors needed: C min Make a field of processing gates: +5 Java programs 10

11. MultiCore: Business as usual ManyCore: More difficult DataFlow: Much more difficult Debugging both, application and configuration code: 5 Java + C min 11

12. MultiCore/ManyCore: Several minutes DataFlow: Several hours (to configure the FPGA structures) Future: Xilinx, Altera, Achronix (UCB 1GHz), Tabula (MIT, 1.6GHz) 12
