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 automatically configuring storage array includes media storage devices coupled together within a network. Preferably, the network is an IEEE 1394-1995 serial bus network. The media storage devices record and retrieve data transmitted within the network. The media storage devices communicate to store and retrieve data over multiple media storage devices. When a record or playback command is received by a media storage device, the media storage devices send communications between themselves to record or transmit the data. Control of operations is transferred between the media storage devices to utilize the capacity of available media storage devices. Preferably, data is recorded utilizing redundancy techniques. Object descriptors are stored within recorded streams of data to facilitate search and retrieval of recorded data. Preferably, the media storage devices accept control instructions directly from devices. Alternatively, a control device provides a control interface between the media storage devices and other devices.

摘要： A multi-protocol media storage device operates according to both the AV/C Command Set and the FCP protocol to record and retrieve data in an isochronous format and the SBP-2 protocol to record and retrieve data in an asynchronous format. Isochronous data is recorded on the media storage device on AV tracks according to the AV/C Command Set. Asynchronous data is recorded on the media storage device in sections called asynchronous spaces. Additionally, isochronous data is recorded in a portion of an asynchronous space as described in one or more operation request blocks delivered according to the SBP-2 protocol. The AV tracks and the asynchronous spaces are each preferably numbered with a unique integer value. A management operation request block (ORB) includes a function field that can have a value indicating that the request is a manage asynchronous space request. Within a manage asynchronous space request a sub-function field indicates that the request is a create, delete or query asynchronous space request. Command ORBs having a request format field value of “0” are performed within the lowest numbered asynchronous space. Command ORBs having a request format field value of “1” are performed within an indicated asynchronous space. Previously recorded data within either an AV track or an asynchronous space can be accessed using both the FCP protocol and the SBP-2 protocol.

摘要： A system and method for effectively implementing isochronous processor cache comprises a memory device for storing high-priority isochronous information, an isochronous cache coupled to the memory device for locally caching the isochronous information from the memory device, and a processor device for accessing and utilizing the isochronous information that is stored in the isochronous cache. The isochronous cache is reserved for storing the isochronous information, and may be reconfigured into a selectable number of cache channels of varying size that each corresponds to an associated isochronous process.

摘要： A node on a bus structure includes a physical interface to the bus structure. The physical interface determines the port on which an inbound bus packet is received and transmits an outbound bus packet only on an appropriate port connected to the destination node. When receiving a bus packet, the physical interface determines if the port on which the packet was received is a secure port. If it is determined that the packet was received on a secure port, the packet is then dumped to a direct memory access channel where the packet is processed as usual without requiring processor intervention. If the packet was received on an unsecure port, the packet is dumped to a general receive area and the processor is interrupted. The processor then examines the packet to determine whether the packet can be processed without affecting the security of the node. When transmitting a bus packet, the port to which the destination node of the bus packet is connected is determined. The bus packet is then only transmitted on this destination port while the other ports within the physical interface circuit are held busy.

摘要： A hardware authentication mechanism ensures that a device receiving a packet of copy-protected data has been authorized by the transmitting device to receive the packet of data. The transmitting device authenticates a receiving device and verifies that the receiving device is authorized to receive the copy-protected data. Once authenticated, the transmitting device then sends a write authentication transaction, including a physical identifier value representing the transmitting device, to the receiving device. This authentication transaction is preferably addressed to a predefined address in the receiving device. This address is preferably communicated from the receiving device to the source device during the earlier authentication process. Alternatively, the address is assigned by convention. In an alternative embodiment, the authentication transaction also contains additional information, such as one or more encryption keys which are needed by the receiving device to decipher and use the copy-protected data. Upon receiving the authentication transaction, the receiving device then latches the physical identifier value into a dedicated register. When a data packet is then received at the receiving device, the interface hardware of the receiving device compares the physical identifier value in the received data packet to the value stored in the dedicated register. If the physical identifier value in the received data packet and the value stored in the dedicated register are the same, the interface hardware receives the data packet. If the physical identifier value in the received data packet and the value stored in the dedicated register are not the same, the interface hardware does not receive the data packet.

摘要： An asynchronous data pipe (ADP) automatically generates transactions necessary to complete asynchronous data transfer operations for an application over a bus structure. The ADP includes a register file which is programmed and initiated by the application. The register file includes the bus speed, transaction label, transaction code, destination node identifier, destination offset address, length of each data packet, packet counter, packet counter bump field, control field and a status field. During a data transfer operation, the ADP generates the transactions necessary to complete the operation over the appropriate range of addresses, using the information in the register file as a template. The ADP increments the value in the destination offset address field for each transaction according to the length of each data packet, unless the incrementing feature has been disabled and the transactions are to take place at a fixed address. The packet counter represents the number of transactions remaining to be generated. The packet counter value is decremented after each packet of data is transferred. The application can increment the packet counter value by writing to the packet counter bump field. A multiplexer is included within a system having multiple ADPs for multiplexing the information from the ADPs onto the bus structure. A demultiplexer is included within a system having multiple ADPs for routing information from the bus structure to the appropriate ADP.

摘要： A system and method for effectively performing isochronous data transfers comprises a network device including an input/output (I/O) bus that is coupled to an input/output (I/O) node and an isochronous-capable network interface. The network interface and the I/O node may send requests to an arbiter for control of the I/O bus to perform a data transfer operation. In accordance with the present invention, an arbiter filter is interposed between the arbiter and both the network interface and the I/O node to filter respective requests for control of the I/O bus. The network interface advantageously provides an isochronous request to the arbiter filter to thereby de-assert conflicting requests so that the network interface may effectively perform a time-sensitive isochronous data transfer.
