... Application Notes Performing Large-Kernel Pixel Interpolation The Cascade Input and Output Ports of the TMC2250A allow the user to stack multiple devices to perform larger interpolation kernels with no decrease in pixel throughput. Figure 12 illustrates a basic application utilizing Mode 11 to realize 4-pixel kernel, also called Cubic Convolution. This example utilizes the TMC2011A Variable-Length Shift Register to compensate for the internal latency of each TMC2250A ...
