摘要： The present invention pertains to an apparatus for and method of mapping texture memory to a texture cache such that cache contention is minimized. Significantly, in one embodiment of the present invention, addresses of the texture memory are mapped to entries of the texture cache according to a predetermined hashing scheme. According to the one embodiment, texture memory is addressed as a virtually contiguous address space by a multi-dimensional index. The multi-dimensional index is further partitioned into a low order bit field and a high order bit field. Low order bits of the multi-dimensional index are directly mapped to low order bits of the cache address. High order bits of the multi-dimensional index are mapped to high order bits of the cache address according to a predetermined address-hashing scheme. Particularly, in one embodiment, high order bits of the multi-dimensional index are selectively “exclusive-or-ed” to generate corresponding addresses of the texture cache.

摘要： A method of a computer graphics system recirculates texture cache misses into a graphics pipeline without stalling the graphics pipeline, increasing the processing speed of the computer graphics system. The method reads data from a texture cache memory by a read request placed in the graphics pipeline sequence, then reads the data from the texture cache memory if the data is stored in the texture cache memory and places the data in the pipeline sequence. If the data is not stored in the texture cache memory, the method recirculates the read request in the pipeline sequence by indicating in the pipeline sequence that the data is not stored in the texture cache memory, placing the read request at a subsequent, determined place in the pipeline sequence, reading the data into the texture cache memory from a main memory, and executing the read request from the subsequent, determined place and after the data has been read into the texture cache memory.

摘要： A spread spectrum system having data transmitted in a spread spectrum signal. Periodic and quasi-periodic signals which act as interference in the spectrum of interest is effectively filtered out by using a linear predictive coding filter. The LPC filter takes a digitized received spread spectrum signal and generates a set of predictive coefficients and a set of error coefficients. The predictive coefficients represent the interfering periodic and/or quasi-periodic signals. As such, the set of predictive coefficients are discarded. The remaining error coefficients represent what is left over and thereby contains the useful transmitted data found within the spread spectrum signal. The error coefficients are used by the signal processing block to extract the transmitted data.

摘要： The present invention provides efficient and effective quality of service for information that is time sensitive (e.g., real time data). An intermediate network communication system and method (e.g., a router) of the present invention performs cut through switching to reduce latency problems for time sensitive information. In one embodiment of the present invention, communication packet header information is encoded with a time sensitive identifier that identifies the information as time sensitive. In one exemplary transfer control protocol/internet protocol TCP/IP implementation of the present invention, time sensitive indication is provided in the link layer information. In one embodiment of the present invention, time sensitive information is dropped if the intermediate network device can not communicate the information within specified timing constraints. In one embodiment of the present invention time sensitive information is cut through routed on a virtual channel and pre-empts non time sensitive information. In one embodiment a communication path probe is cut through routed via intermediate network devices to establish a communication path before other information is communicated from a originating source to a final destination. In one embodiment the present invention leverages previously collected information to establish a communication path. In one embodiment the present invention, an intermediate network device establishes a second communication link if a first communication link is unavailable.

摘要： A system and method for restoring bits of pixels prior to display where the original bits of the pixels were truncated compares each pixel to its neighbors to determine the relative value of each pixel as compared to its neighbors. First, the truncated pixel is shifted. That is, the remaining bits of the pixel are shifted to the left and additional bits are added in the least significant bit positions. Next, the pixel is compared to its neighbors to determine their relative values. For each neighbor that is greater than the pixel in question, the truncated shifted pixel is incremented by one. Similarly, for each neighbor that is less than the pixel in question, the truncated shifted pixel is decremented by one. Once the pixel is evaluated relative to its neighboring pixels, determination of the restored pixel is complete. The restored pixel can then be displayed.
