摘要： A computer system optimized for real-time applications which provides increased performance over current computer architectures. The system includes a standard local system bus or expansion bus, such as the PCI bus, and may also include a dedicated real-time bus or multimedia bus. Various multimedia devices are coupled to one or more of the expansion bus and/or the multimedia bus. The computer system includes byte slicing and/or data packing logic coupled to one or more of the expansion bus and/or the multimedia bus which operates to allow different data streams to use different byte channels simultaneously. Thus the byte sliced bus allows different peripherals to share the bus simultaneously. The byte slicing logic thus may assign one data stream to a subset of the total byte lanes on the multimedia bus, and fill the unused byte lanes with another data stream. The data packing logic may optimally fill the bus with data having more or fewer bits than the bus. The computer system of the present invention thus provides much greater performance for real-time applications than prior systems.

摘要： A system and method for choosing communication pathways for data transfers on a computer chip based on desired latency and bandwidth characteristics. On a computer chip including a network of resources, those resources are allocated based upon the needs of the various components of the computer chip. Typical resources on the computer chip include a first bus with a plurality of data lines and control lines and having first bandwidth and latency characteristics, a second bus with a plurality of data lines and control lines having second bandwidth and latency characteristics, and a plurality of devices coupled to the first bus and second bus. Each device includes interface logic for accessing and performing transfers on the first and second buses. Each device is operable to select either the first or second bus depending on desired bandwidth and latency characteristics. Normally the first bandwidth is greater than the second bandwidth. Each device selects the first bus for higher speed transfers or the second bus for lower speed transfers. When the first latency is shorter than the second latency, each of the devices select the first bus for lower latency transfers and the second bus for higher latency transfers. Other characteristics which may be varies by each device according to the transmission needs of the particular device include clock rate, block size, and bus protocol depending upon desired bandwidth and latency characteristics. For highest possible bandwidth transfers, a multiple bus transfer may be requested by any device.

摘要： A computer chip including a data transfer network which comprises a plurality of communications links for transmitting data, a plurality of communication nodes, and a plurality of modules. Each of the communication nodes is directly connected to two or more other communication nodes through respective ones of the communications links. Each communication node is operable to communicate data over the respective one of the communications links. Each module is coupled to at least one of the communication nodes, and the modules are operable to communicate with each other through the communication nodes. The communication nodes are operable to create dynamic routes for the data transferred between any two or more of the plurality of modules over the respective ones of the communications links. The communication nodes form the dynamic routes based on statistical data on previous transmissions between the modules. Each communication node may include respective configuration logic for dynamically configuring the dynamic routes, and each configuration logic may include a memory for storing the statistical data on previous transmissions that passed through the respective communications node. The data transfer network may also comprise a routing module for controlling the dynamic routes based on statistical data. The routing module couples to each communication node and monitors the configuration logic. When present and functioning, the routing module adapts the dynamic routes based on an analysis of the statistical data. The statistical data includes one or more of the following for each respective transmission: priority, source module, destination module, number of data units, elapsed transfer time or minimum required transfer time, and total number of transmissions which pass through a given communications node.

摘要： A microprocessor including a context save unit is provided. The context save unit is configured to periodically perform context saves. When the microprocessor receives an interrupt signal, the microprocessor enters the interrupt service routine without performing a context save. After completing execution of the interrupt service routine, the microprocessor restores the most recently saved context and begins executing the task at that saved context. The interrupt service routine is entered rapidly but the interrupt service routine does not include instructions for saving the registers which it utilizes to perform its function. The context save unit is configured to perform a context save at the occurrence of a variety of events. A fixed or variable time interval may be selected, and each interval includes several options.

摘要： A noise environment is sampled via microphone. A processor generates a cancellation signal to offset the effects of the noise to a listener. The cancellation signal is converted into a sample signal compatible with a synthesizer. The synthesizer adjusts the pitch, amplitude and timing of a sample of a patch set to create a substantially continuous output cancellation signal. The continuous output cancellation signal is output via a speaker. The output cancellation signal combines with the noise environment to reduce the effects of the noise environment on the listener. Alternatively, in previously characterized noise environments, one or more cancellation signals may be stored in processor. The processor receives a user input selecting the appropriate cancellation signal and adjusting the parameters of the cancellation signal. After the processor has calculated or selected the cancellation signal and transferred the sampled signal to the synthesizer, the processor is no longer involved in the generation of the cancellation signal. Therefore, the noise cancellation function requires relatively little processing power and is accomplished without the need for special purpose hardware.
