    摘要： In a first embodiment, an applications programming interface (API) implements and manages isochronous and asychronous data transfer operations between an application and a bus structure. During an asynchronous transfer the API includes the ability to transfer any amount of data between one or more local data buffers within the application and a range of addresses over the bus structure using one or more asynchronous transactions. An automatic transaction generator may be used to automatically generate the transactions necessary to complete the data transfer. The API also includes the ability to transfer data between the application and another node on the bus structure isochronously over a dedicated channel. During an isochronous data transfer, a buffer management scheme is used to manage a linked list of data buffer descriptors. During isochronous transfer of data, the API provides implementation of a resynchronization event in the stream of data allowing for resynchronization by the application to a specific point within the data. Implementation is also provided for a callback routine for each buffer in the list which calls the application at a predetermined point during the transfer of data. An isochronous API of the preferred embodiment presents a virtual representation of a plug, using a plug handle, to the application. The isochronous API notifies a client application of any state changes on a connected plug through the event handle. The isochronous API also manages buffers utilized during a data operation by attaching and detaching the buffers to the connected plug, as appropriate, to mange the data flow.

    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 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： An isochronous data pipe provides a bi-directional path for data between an application and a bus structure. The isochronous data pipe includes the ability to send, receive and perform manipulations on any isochronous stream of data, including data on any number of isochronous channels. The isochronous data pipe is a programmable sequencer that operates on the stream of isochronous data as it passes through the isochronous data pipe. The isochronous data pipe is programmed by an application to perform specific operations on the stream of data before the data is either transmitted across the bus structure or sent to the application, thereby pre-processing and manipulating the data before it is delivered to its destination. The operations are performed on both the packet header and the data field of the data packet. The isochronous data pipe can be stopped and started on the occurrence of specific events. In an alternate embodiment of the present invention, the isochronous data pipe is programmed to send and receive both isochronous and asynchronous data, including generating requests and appropriate packet headers.
