Abstract: Color conversion systems and methods using an interpolation table that minimizes interpolation color value generation times and reduces memory storage of interpolation tables. A first color conversion method and system reduces interpolation table generation times by generating interpolation color values on an "as needed" basis while performing color conversions. A second color conversion method minimizes interpolation table memory storage by dividing the interpolation table into segments, allocating primary memory storage to store only a given number of segments and establishing a segment status bit array to indicate whether a given segment is currently stored in primary memory. A third system and method combines both the first and second methods so that both interpolation table generation times and table memory storage is reduced.

Abstract: A system and method for controlling DRAM is described. According to exemplary embodiments of the present invention, a memory subsystem can be populated by end users with any of a variety of DRAM chips. A memory controller will size each memory bank and determine whether paired memory banks are to be configured as interleaved or non-interleaved based upon the detected DRAM population. Bank selection logic is designed to account for both size and status (interleaved or non-interleaved) when determining which memory bank contains a memory location of interest. Row and column addressing is selected to minimize decoding of an incoming system address and reduce DRAM access time.

Abstract: A system and method for performing speaker adaptation in a speech recognition system which includes a set of reference models corresponding to speech data from a plurality of speakers. The speech data is represented by a plurality of acoustic models and corresponding sub-events, and each sub-event includes one or more observations of speech data. A degree of lateral tying is computed between each pair of sub-events, wherein the degree of tying indicates the degree to which a first observation in a first sub-event contributes to the remaining sub-events. When adaptation data from a new speaker becomes available, a new observation from adaptation data is assigned to one of the sub-events. Each of the sub-events is then populated with the observations contained in the assigned sub-event based on the degree of lateral tying that was computed between each pair of sub-events.

The voltage supply plane regions are split to reduce the total number of PCB conductive layers. Voltage supply plane regions are configured to match the device voltage requirements and their placement on the PCB. In the case in which a circuit includes a device having two voltage supply requirements, a first set of the device's power supply pins are fixedly coupled to a first voltage supply plane region and a second set of the device's power supply pins are fixedly coupled to a second voltage supply plane region. In this instance, each of the first and second voltage supply plane regions are fixedly connectable to external voltage supplies or to a voltage regulator according to the voltage supply requirements of the device.

Abstract: Storage and access of compressed data via separately compressed and stored variable size logical blocks. Portions of a data file are compressed until they reach a logical block size which matches a given sector size or block of storage space. The compressed logical block (portion of compressed data) is stored into a sector allocated to it and a table is built correlating the range of original data to the sector storing the compressed data. When it is desired to read a given portion of data within a stored compressed data file, it is first determined where within the original data file the desired portion resided. Then, the correlation table created as part of the compression and storage sequence is used to determine which sector contains the desired data.

Abstract: The branching decision for each node in a vector quantization (VQ) binary tree is made by a simple comparison of a pre-selected element of the candidate vector with a stored threshold resulting in a binary decision for reaching the next lower level. Each node has a preassigned element and threshold value. Conventional centroid distance training techniques (such as LBG and k-means) are used to establish code-book indices corresponding to a set of VQ centroids. The set of training vectors are used a second time to select a vector element and threshold value at each node that approximately splits the data evenly. After processing the training vectors through the binary tree using threshold decisions, a histogram is generated for each code-book index that represents the number of times a training vector belonging to a given index set appeared at each index. The final quantization is accomplished by processing and then selecting the nearest centroid belonging to that histogram.

Abstract: A system for object oriented message filtering for selectively transferring a message between a client task and one or more server tasks for preprocessing, processing, and postprocessing comprises an object database having a filter object memory, an object management unit, a message transaction unit, and a locking unit. The object management unit creates a port object and one or more associated target message objects. The object management unit selectively creates one or more filter objects associated with a target message object, and selectively associates a preprocessor message object, a postprocessor message object, or both a preprocessor message object and a postprocessor message object with each filter object. The message transaction unit selectively routes a message sent by a client task and directed to a target message object to one or more associated preprocessor message objects prior to delivering the message to the target message object.

Abstract: A software program running on a computer is automatically managed, monitored and updated with a newer version in a completely automated fashion, without interruption of its primary function, and in a manner that is completely transparent to the user of the computer. This is achieved by means of a control module that performs the functions of locating and identifying other versions of its associated program, determining whether the other versions are older or newer than currently stored versions, and downloading a newer version. Multiple versions of the program can remain accessible on the computer, and the control module manages the launching of a particular version that may be required. Statistical data relating to the launching and operation of the program is collected, and uploaded to a central location on a regular basis.

Abstract: A method of designing improved CMOS input circuits by understanding and selecting appropriate drive strength for a CMOS output from a previous stage. The method involves modeling the net using HSPICE and including a transit time term to accurately model charge storage, then size drivers as needed to keep the V.sub.ss clamps out of forward conduction. Excessive ringing can cause data errors in the input stage if unterminated, falling edge transitions in such a net can turn on a receiver's V.sub.ss clamp diode (stored charge in the V.sub.ss clamp diode combined with the line's inductance and the receiver's capacitance form an energized resonant circuit which can release energy at a time to cause a data glitch). Currently, XNS simulation miscalculates the ring amplitude by a factor of three. Driver scaling and termination can eliminate the problem by keeping the receiver's V.sub.ss clamp out of forward conduction. Driver sizing can control the problem.

Abstract: A subroutine execution time tracer that is able to trace execution times of software subroutines regardless of whether the subroutines are invoked or exited using standard or non-standard subroutine calling conventions is described. A head patch is placed at the beginning of a software subroutine, and a tail patch is placed at the end of the software routine. The invention uses the head patch to examine the return address on the system stack before replacing the return address with the address of a tail patch. If the return address on the system stack already corresponds to a tail patch, then a counter associated with the tail patch is incremented. The counter serves to notify the tail patch that when invoked it must log an additional exit event. This allows subroutines which "jump" to other subroutines (i.e., non-standard subroutine calls) to be properly traced. The invention also configures the tail patch as an internal code stack.

Abstract: An apparatus and method are provided for automatically adjusting a pixel sampling clock frequency and phase of a video display to match the frequency and phase of a pixel clock used to generate an incoming video signal being received by the video display. Voltage transitions are detected between pixel intensities in a video signal. The voltage transitions are compared with pixel sampling clock pulse signals of the video display in order to correctly match the frequency and phase of the video signal, and thus produce a more stable and noise-free image on the video display.
