摘要： A bus arbitration system, medium, and method. The bus arbitration system can arbitrate access to a bus for a plurality of masters, requesting the use of a bus to which at least one slave is connected, and may include a bus use granting unit that outputs a plurality of bus grant signals for granting the use of the bus to the plurality of masters that request the use of the bus at the same time, a simultaneous processing available signal selecting unit that selects a predetermined number of operation instruction signals having a predetermined similarity, from among a plurality of operation instruction signals that are input from the masters, in response to the bus grant signals, and an operation instructing unit that simultaneously transmits the selected operation instruction signals to the slave through the bus.

摘要： An effective structure of a pixel cache for use in a three-dimensional (3D) graphics accelerator is provided. The pixel cache includes a z-data storage unit that reads z-data from a frame memory and provides the read z-data to a pixel rasterization pipeline; and a color data storage unit that in advance reads and stores color data from the frame memory at the same time when the z-data storage unit reads the z-data from the frame memory, and provides the color data to the pixel rasterization pipeline only when the result of predetermined z-test is determined to be a success in the pixel rasterization pipeline. Accordingly, the pixel cache structure enables only color data required to be read and stored in advance before processing of the color data, thereby preventing access latency, increasing the efficiency of a color cache, and reducing power consumption.
