    摘要: An apparatus for dispatching a processing element to a program location based on a channel number of received data includes a channel pointer register having a number of storage locations each with a channel number field, a valid bit field and a corresponding instruction pointer field. When an isochronous channel is allocated for use for reception, the host device programs the channel number and a corresponding instruction pointer value into a storage location. When a storage location is programmed, a valid bit within that storage location is also preferably set. The corresponding instruction pointer value points to a series of instructions which are to be used to process data received on that isochronous channel. When isochronous data is then received, the channel number on which the data is received is compared to the channel numbers within the valid storage locations in the channel pointer register. If one of the channel numbers within a valid storage location matches the channel number of the received data, then the corresponding instruction pointer value is output and the data is processed according to a series of instructions beginning at the location specified by the corresponding instruction pointer value. Otherwise, if the channel number of the received data does not match any of the channel numbers within valid storage locations then a default instruction pointer value is output and the received data is processed according to a series of instructions beginning at the location specified by the default instruction pointer value.

    摘要: A system and method for multi-level context switching in an electronic network comprises a control state machine configured to implement a data priority scheme, a return address generator configured to hold and release return addresses for interrupted instruction modules in accordance with the data priority scheme and context information from the electronic network, and a processor configured to process data from the electronic network in accordance with the data priority scheme and the context information. Receive registers stores data received from the electronic network. The control state machine includes a switch address generator and a program counter select. The switch address generator outputs a switch address, which is an address for a first instruction for a selected-context instruction module. The return address generator holds and releases the return addresses, which are addresses of next consecutive instructions, when an instruction module is interrupted for a context switch. The program counter select outputs a switch address, a return address, or a next consecutive address to select the appropriate instruction in the memory for execution by the processor.

    摘要: A system and method for context switching in an electronic network comprises a memory configured to store instruction modules, each instruction module corresponding to a context, a processor that executes the instruction modules, and a control state machine. The control state machine selects one of the instruction modules for execution by the processor according to context information from the electronic network. The control state machine includes a switch address generator, a return address register, and a program counter select. The switch address generator outputs a switch address, which is an address for a first instruction for a selected-context instruction module. The return address register stores a return address, which is an address of a next consecutive instruction, when an instruction module is interrupted for a context switch. The program counter select outputs the switch address, the return address, or a next consecutive address to select the appropriate instruction in the memory for execution by the processor.

    摘要: A dispatching apparatus includes a channel pointer register having storage locations, each with fields for channel number, valid bit, and corresponding instruction pointer which points to instructions for processing data for that channel. When an isochronous channel is allocated for reception, the host programs the channel number and corresponding instruction pointer value into a storage location and sets the corresponding valid bit. When data is received, the channel number is compared to channel numbers within valid storage locations. The data is processed according to instructions located at the corresponding instruction pointer value if there is a channel number match or instructions at the default instruction pointer value if there is no match. Default instructions include broadcasting data received on one channel to appropriate channels, multicasting data, handling errors and exceptions, ignoring a channel, routing data to another channel, monitoring active channels on the bus, and other actions for processing data.

    摘要: A system and method for fast data transfers in an electronic network comprises a data transfer engine configured to independently execute data transfer instructions and a processor configured to forward the data transfer instructions to the data transfer engine. The data transfer engine preferably executes the data transfer instructions while the processor proceeds to execute a next instruction. The data transfer engine includes a transmit engine that executes transmit transfer instructions and a receive engine that executes receive transfer instructions. The transmit engine and the receive engine operate independently and thus may operate concurrently.

    摘要: A method for implementing scheduling mechanisms with selectable resource modes comprises at least one resource characterization set that includes a plurality of resource characterizations that each have resource requirements for executing a requested process. The plurality of resource characterizations may include a most mode, a best mode, and a worst mode. An allocation manager may then select a resource mode, and compare the corresponding resource requirements for the requested process to the currently-available device resources. The allocation manager may then authorize or deny the requested process depending upon whether the currently-available resources are sufficient to adequately service the resource requirements of the requested process.
