  • Patent number: 8254189
    Abstract: Disclosed is a method for tuning control signals associated with one or more memory devices. The method includes performing a number of memory access operations on at least one memory device and recording results of the memory access operations. Specifically, the memory access operations are performed with different time delays for a first edge of a control signal. The control signal used for capturing data is provided by the at least one memory device. The method further includes selecting a time delay from the time delays used in the memory access operations. Moreover, the method includes utilizing the selected time delay in performing subsequent memory access operations on the at least one memory device. Also disclosed is a system including at least one memory device and an integrated circuit operatively coupled to the at least one memory device. The system incorporates the method for tuning control signals.

  • Publication number: 20080002899
    Abstract: A method for dynamically compressing image data to fit within a predefined memory capacity of a memory buffer includes dividing the image data into a plurality of data bands; determining an average band memory size in the memory buffer for each data band of the plurality of data bands; compressing a current data band at a compression quality level; and adjusting the compression quality level for a next data band of the plurality of bans to be compressed based on the average band memory size and a compressed memory size of the current data band.
