Semiconductor memory asynchronous pipeline
An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage.

Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it.

Image registration using a modified log polar transformation
A system and method for registering a test image with a reference image requires decimation of both images to create corresponding image pyramids. A Log-Polar Transformation (LPT) is then applied to corresponding pixels from the same highest levels of the respective pyramids. Next, these pixels are manipulated to establish a Normalized Correlation Coefficient (NCC) for their respective correlations. Approximately the highest 10% of correlated pixels are then retained to identify related pixels in the next lower level of their respective pyramids. Again, LPT is applied to these related pixels and they, in turn, are manipulated to establish NCC correlations for identifying pixels to be retained. This process is successively accomplished for each lower level of the pyramid until the lowest levels (i.e. the test image and the reference image) are correlated and used for registration of the test image.
