摘要： Systems and methods for compositing an image directly from multiple source image data for reducing system memory footprint and bandwidth and for improving color quality of the image. The image is divided into spans, lines, and slices. Each line includes at least one span and each slice includes at least one line. All lines in a slice have spans associated with identical sources. An image is composited by reading the image data directly from one or more sources of each span. If necessary, the sources are blended. A control structure is used to provide the image context and identifies the sources of the spans. The control structure includes headers for each data stream from each source of each span. Also, the color quality of the image is improved by reducing the number of color space conversions that occur as the image is composited. All sources in the same color space are blended before being blended with sources from other color spaces. Preferably, no more than a single color conversion is required.

摘要： In a network of interconnected multimedia source, transfer, and sink ports, the described subject matter defers port parameter selection until substantially all relevant information is available. Specifically, parameters are negotiated between multiple ports by specifying parameter sets corresponding to the ports. Each parameter set is expressed as a list of constraints on allowable values or ranges of values. When connecting multiple ports, the constraints on their parameter sets are conjoined to form a parameter set intersection. The parameter sets of the ports are limited to values included in the parameter set intersection. Parameter sets relating to other ports are potentially limited based on the intersection results. The conjoining and limiting operations are repeated until the various parameter sets exhibit no further limitations in response to further repetitions. This process is repeated for all port interconnections. Subsequently, values for the port parameters are selected from the limited parameter sets.

摘要： Systems and methods for verifying the authorization of a server to provide network resources to a client. At selected times, the client asserts an authorization interrupt, which will disable some or all non-essential functions of the client unless the server's authorization is verified within an allotted period of time. The client creates a client message by generating a random number and combining it with a client identifier and a value that specifies the current time. The client message is encrypted and sent to the server. Only authorized servers can decrypt the client message and create an encrypted service message that includes the random number. The service message can also contain an authorization code specifying the services that the client may receive, and an expiration count indicating when the authorization procedure will be repeated. The client receives and decrypts the service message. If the random number in the service message is found to be the same as the random number in the client message, the server is authorized, and the client is enabled to exhibit a selected level of functionality. The client can be associated with a smart card or another intelligent peripheral that verifies the authorization of the server in behalf of the client.

摘要： A digital signal processing architecture is inherently cyclical in nature, by providing a timer which can be programmed to reset the processor and return to the first instruction periodically, typically once each sample of the input sample stream. Pipeline operation is enhanced through the use of a double buffering system in which operands are latched into the first stage of a double buffer as soon as they are ready, but they are transferred to the second stage only when the last-ready operand is available and the computation unit is ready to receive the operands. The computation unit receives the operands in the second stage of the buffers. The processor communicates with an external unit via a random access memory and a plurality of FIFOs. Each FIFO is associated with a respective location in the random access memory. Whenever the processor retrieves a value from one of these locations in the random access memory, control means automatically refills that location from the corresponding FIFO. Similarly, whenever the processor writes data to one of the locations corresponding to an output FIFO, control means automatically recognizes that and copies the data into the corresponding output FIFO. Output FIFO writes may be emulated by an address latch and a data latch in a path to the FIFOs. The processor also includes instructions with a "write-back" bit, a novel register addressing mode, a "branch from" instruction, an invisible move function, and an operand mask register.

摘要： Systems for servicing the data and memory requirements of system devices. A DMA engine that includes a data reservoir is provided that manages and arbitrates the data requests from the system devices. An arbitration unit is provided that only allows eligible devices to make a data request in any given cycle to ensure that all devices will be serviced within a programmable time period. The data reservoir contains the data buffers for each channel of each device. A memory interface ensures that sufficient data for each channel is present in the data reservoir by making requests to a system's memory based on an analysis of each channel. Based on this analysis, a request is either made to the system's main memory, or the channel waits until it is evaluated again in the future. Each channel is thereby guaranteed a response time.
