MAPPING THE NUMERICAL SIMULATIONS OF PARTIAL DIFFERENTIAL EQUATIONS 150 112.5 75 37.5 Number of BlockRAMs 0 4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 Precision (bit) Figure 2.17: Number of block-RAMs in the arithmetic unit sor was redesigned according to the discretized version of the partial differential equations optimized for the dedicated elements (BlockRAM, multiplier) of the FPGA. A process is developed for the optimal bandwidth management between the processing elements and the memory on Xilinx Virtex and on IBM Cell architectures. It turned out, that placing a memory element close to the processor results in a beneficial effect on the computing speed, which provides a minimum one order of magnitude higher speedup independently from the dimension of the problem. One order of magnitude speedup can be achieved between an inhomogenous architecture, like the IBM Cell, and a custom architecture optimized for Xilinx Virtex FPGA using the same area, dissipated power and precision. During the simulation of CFD on body fitted mesh geometry the Xilinx Virtex 5 SX240T running on 410 MHz is 8 times faster, than the IBM Cell architecture with 8 synergistic processing element running on 3.2 GHz. Their dissipated power and area are in the same range, 85 Watt, 253mm 2 and 30 Watt, 400 mm 2 respectively. Considering the IBM Cell processor’s computing power per watt performance as
