Abstract: The present invention comprises a method and apparatus for selectively providing pre-emphasis to the output of a first driver during an initial portion of certain data transitions while transmitting data along a data bus from a source to a destination, with the certain data transitions being determined as a function of the content of the history of prior transmitted data cells. In the preferred embodiment, a pre-emphasis driver is connected in parallel to a normal driver and the pre-emphasis driver is activated preferably during the initial portion of a data transition to provide pre-emphasis in response to a control signal being applied to the pre-emphasis driver. The preferred embodiment of the present invention also comprises a sequence detector and control for monitoring the data cells or bits that are inputted to the normal driver to provide a history of the voltage levels of the data bits that are input to the normal driver.

Abstract: A system and method for allocating data among first and second banks of at least one SDRAM, the data including first, second and third words to be accessed during consecutive read operations. The method includes the following steps: storing the first and third words within the first bank, and storing the second word within the second bank. The texture mapping computer graphics system includes a host computer with a main memory that stores texture data including a plurality of texels, and a local memory that stores at least a portion of the texture data. The local memory includes at least one SDRAM.
