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.

摘要： An applications programming interface implements and manages isochronous and asynchronous data transfer operations between an application and a bus structure. During an asyncronous 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. This linked descriptor list can form a circular list of buffers and include a forward pointer to the next buffer in the list and a backward pointer to the previous buffer in the list for each buffer. The linked descriptor list may also form a linear list to which the application can append additional buffers or remove existing buffers from the list. During isochronous transfers 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.

摘要： In a first embodiment, an applications programming interface (API) implements and manages isochronous and asynchronous data transfer operations between an application and a bus structure. During an synchronous 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 transfers 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 manage the data flow.

摘要： Both small frames and large frames of data are transmitted from a producer device to a consumer device over an IEEE 1394 serial data bus. The small frames of data are preferably transmitted to a small frame buffer associated with a plug at the consumer device. Each transfer of a small frame generates an interrupt at the consumer device when the transfer is complete. For the transfer of large frames of data, the consumer device programs an array of page table entries into the plug control register of the producer device, prior to a transfer of a large frame of data. Each of the page table entries includes a starting address of a memory page at the consumer device to which data can be written. Together, these memory pages specified by the page table entries form a large frame buffer at the consumer device for receiving a large frame of data from the producer device. Preferably, the array of page table entries can be updated by the consumer device, as appropriate, between frame transfers. When transferring a large frame of data, the producer device begins writing to the first page specified in the first page table entry and continues in order, writing to the pages specified in the page table entries, until the entire frame has been transferred. When the entire large frame of data has been transferred, the producer device then updates the plug control register at the consumer device to notify the consumer device that the entire large frame has been transferred.
