    摘要: One or more aspects of the present invention pertain to transferring digital data between first and second domains, where a first clock of the first domain operates at a first frequency and a second clock of the second domain operates at a second frequency, where the first frequency is higher than the second frequency, and where the first and second clocks have arbitrary phase relationships relative to one another. Techniques employed facilitate efficient digital data transfer between the first and second domains while conserving valuable semiconductor real estate.

    摘要: A multi media card includes a plurality of memory modules and an extraneous command decoder. The extraneous command decoder decodes a predetermined command for determining a selected memory module to be accessed from the plurality of memory modules, when a predetermined bit of the predetermined command is set to a predetermined logic level.

    摘要: A display image enhancement apparatus and method are disclosed for use in generating additional pixel data from input image data, where a window of input pixel data is used to generate data for an additional pixel to be placed substantially in the center of the window. The display image enhancement apparatus includes memory elements that is capable of receiving a chain of input pixel data and storing at least the window of input pixel data, where the window of input pixels includes a plurality of pixel pairs each of which respectively represents an angle of correlation. The display image enhancement apparatus also includes instant angle detection circuitry capable of receiving the input pixel data stored in the memory elements and determining an instant angle having the highest correlation based on differential values of at least some of the pixel pairs, where a differential value is the difference between the values of pixels in a pixel pair. The display image enhancement apparatus further includes substantial angle detection circuitry capable of determining a substantial angle having the highest correlation based on filtered differential values of at least some of the pixel pairs. Angle confirmation circuitry is provided to determine an interpolation angle based on the instant angle and the substantial angle. The display image enhancement apparatus employs an interpolator that is capable of determining the value of the additional pixel based on the values of pixels in the pixel pair corresponding to the interpolation angle.

    摘要: A system is presented that facilitates masking data in write data bound for a memory device. The system contains a memory controller and a memory array communicatively coupled to the memory controller. The memory controller sends a write command and write data to the memory array and the memory array updates data contained therein based upon the write command and write data. If the write operation requires a byte mask, the controller sends a byte mask command via a command bus linking the controller and the memory array. Accordingly, separate and dedicated byte mask pins or bus is not necessary to convey byte mask information.
