摘要： A method, apparatus and algorithm for quickly detecting an address match in a deeply pipelined processor design in a manner that may be implemented using a minimum of physical space in the critical area of the processor. The address comparison is split into two parts. The first part is a fast, partial address match comparator system. The second part is a slower, full address match comparator system. If a partial match between a requested address and a registry address is detected, then execution of the program or set of instructions requesting the address is temporarily suspended while a full address match check is performed. If the full address match check results in a full match between the requested address and a registry address, then the program or set of instructions is interrupted and stopped. Otherwise, the program or set of instructions continues execution.

摘要： Method, system and computer program product for generating effective addresses in a data processing system. A method, in a data processing system, for generating an effective address includes generating a first portion of the effective address by calculating a first plurality of effective address bits of the effective address, and generating a second portion of the effective address by guessing a second plurality of effective address bits of the effective address. By intelligently guessing a plurality of the effective address bits that form the effective address, the effective address can be generated and sent to a translation unit more quickly than in a system in which all the effective address bits of the effective address are calculated. The method and system is particularly suitable for generating effective addresses in a CAM-based effective address translation design in a multi-threaded environment.

摘要： A method, system, and computer program product for supporting multiple fetch requests to the same congruence class in an n-way set associative cache. Responsive to receiving an incoming fetch instruction at a load/store unit, outstanding valid fetch entries in the n-way set associative cache that have the same cache congruence class as the incoming fetch instruction are identified. SetIDs in used by these identified outstanding valid fetch entries are determined. A resulting setID is assigned to the incoming fetch instruction based on the identified setIDs, wherein the resulting setID assigned is a setID not currently in use by the outstanding valid fetch entries. The resulting setID for the incoming fetch instruction is written in a corresponding entry in the n-way set associative cache.

摘要： A method, apparatus, and computer program product are disclosed in a data processing system for sharing data in a cache among multiple threads in a simultaneous multi-threaded (SMT) processor. The SMT processor executes multiple threads concurrently during each clock cycle. The cache is dynamically allocated for use among the multiple threads. Portions of the cache are capable of being designated to store private data that is used exclusively by only a first one of the threads. The portions of the cache are capable of being designated to store shared data that can be used by any one of the multiple threads. The size of the portions can be changed dynamically during execution of the threads.

摘要： A digital signal decoder system for receiving compressed encoded digitized video signals and transmitting decompressed decoded digital video signals with accurate expansion for various aspect ratios. This is accomplished through convolution multiplication carried out in 4-tuple parallel with 4-2 counters through a folding serial adder which creates a convolution sum of pixels of the motion compensated data stream to thereby expand the output video display to the desired aspect ratio.

摘要： An apparatus, circuit arrangement, program product and method of scaling an image horizontally partition a source image into a plurality of partitions, with each partition having a width that is no greater than the width of a line buffer used to scale the image. By partitioning an image into a plurality of partitions, the overall width of the scaled image is not constrained by the width of the line buffer. As a result, in many instances line buffers that are significantly smaller than conventional full-width line buffers may be used to generate scaled images that are substantially wider than may be generated by conventional buffers. Moreover, when implemented in hardware, the line buffers typically occupy significantly less real estate on an integrated circuit, thus reducing both cost and power consumption.

摘要： A digital video stream is digitally scaled to properly display on a device having a horizontal to vertical aspect ratio different than the source aspect ratio leaving a blank area on the device. Graphic data is digitally scaled separately to extend partially or completely into and therefore use the blank area. A compositing blender digitally combines the two prior to a display encoder which produces analog signals for driving the display device.
