    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.

    摘要： A method for determining a transmission time of collected context information at a sensor node in a communication system that includes a client, at least one sensor node collecting context information, and an access point (AP) forwarding the context information received from the sensor node to the client. The communication system operates in a session layer of protocol layers of open systems interconnection (OSI). The sensor node calculates a transmission period in which the collected context information is transmitted, and randomly determines a transmission time at which the context information is transmitted within the calculated transmission period. Since the collected context information is transmitted at the transmission time randomly determined by the sensor node, the load on the AP can be balanced.
