Given the proposed architecture of a single SAR BP engine as a $4\times 8$ rectangular array of tiles capable of achieving ~400 Msps pixel-by-pixel throughput, these assumptions can be inserted back into the system partitioning spreadsheet to investigate the capability of larger solutions using several identical instances of this baseline engine. Each engine instance could be assigned its own portion of the target output image to realize a linear scaling in throughput capacity. The resulting system frame rate is shown in the chart below. The baseline engine achieves a system frame rate of 2.6 fps. A design with eight engine instances can achieve a system frame rate of 20.8 fps in principle.
