IMAGE PROCESSING: FFT processor performs phase correlation
… on a single 64 × 64, 8-bit image is 768 clock cycles or approximately 6 µs. To perform image correlation ..... Because the co-processor board requires 768 clock cycles for the 2-D FFT and 128 clock cycles for the multiplication, the resulting throughput …

High-speed cameras target motion analysis
… flip-flops and some other logic. A 2-D 8 × 8-DCT can then be built with two of these blocks. This takes eight clock cycles , and has a 16-clock-cycle latency. To implement the 660-Mpixel/s data rate, these blocks must run at a minimum …

PC tools speed machine-vision software deployment
… point and MMX instructions cannot normally be intermixed without severe performance penalties. It takes about 50 clock cycles to toggle the floating-point register set between floating-point use and MMX operation. Despite this impediment …
