Abstract(in English) | So far we have proposed systolic computational-memory(SCM)architecture for high-performance and scalable computation based on the finite difference methods. The SCM architecture has a completely parallel array structure to achieve scalable performance to the increased hardware resources of a multi-FPGA system. The problem is that real-world implementation requires globally asynchronous and locally synchronous(GALS)design for scalably operating over multiple FPGAs with different clock domains. This paper presents GALS design of SCM arrays(SCMA)for asynchronous communication and a stall mechanism to guarantee the data synchronization among processing elements of different clock domains. Prototype implementation with ALTERA Stratix III FPGAs shows that the proposed design does not give a big overhead in operating frequency and hardware resource utilization. We also evaluate the scalability of the SCMA over multiple FPGAs considering actual stall cycles. |
