Abstract: An improved interface technique for use in a southbridge or I/O hub or in similar devices is provided where non-posted read requests are received from at least one requestor, and upstream commands based on these requests are transmitted. Response data is received in reply to commands that were previously transmitted, and responses are transmitted to the at least one requester based on the response data. A buffer unit is provided for storing command identification data that identifies commands that were already transmitted or that are still to be transmitted, and response availability data that specifies response data that has been received by the receive engine. The improvement may enable multiple outstanding read requests.

Abstract: In a method for recording and forwarding vital signs of a user, vital signs are measured, possibly linked, and displayed to the user. Once the user has accepted the displayed vital signs or their linkages, the user releases them for transmission by way of an authentification.

Each circuit unit can send requests to the other one and send back a response when receiving a request that requires a response. The first circuit unit is connected to the second circuit unit to send to the second circuit unit request data relating to a request to be sent by the first circuit unit and response data relating to a response to be sent by the first circuit unit over a shared signal line.

Abstract: An interrupt processing technique is provided where an interrupt message is sent to an interrupt controller of a processor in response to an interrupt request from an individual device. The interrupt message comprises a memory address and interrupt status information. The memory address is specifically allocated to the device that has issued the interrupt request. The interrupt status information indicates an interrupt status of the device. An interrupt table that is stored in the memory is updated by the interrupt controller using the interrupt status information comprised in the interrupt message. The interrupt table holds device specific interrupt statuses. Updating the interrupt table comprises addressing the memory using the memory address in the interrupt message.

Abstract: An ATA (Advanced Technology Attachment) controller is provided that comprises at least one parallel port for connecting to at least one ATA compliant storage device, and at least one serial port for connecting to at least one SATA (Serial ATA) compliant storage device. Further, there is a port switching unit provided for switching to at least one of the parallel and serial ports to enable data transfer to and/or from a storage device connected to the port. This enables a software driven reconfiguration making it possible to switch between a mode where the controller behaves like a conventional ATA controller, and a mode where the controller behaves like a conventional SATA controller. A significant amount of hardware may be reused.

Abstract: A command storage technique that fulfils ordering rules is provided. This technique may be used in HyperTransport compliant southbridge devices. A command transmit engine comprises a command storage unit that is adapted to receive incoming commands of different command types and store the command in the order in which the commands were received. The command transmit engine further comprises an ordering rule controller that is connected to the command storage unit to select stored commands to be transmitted. The ordering rule controller is adapted to perform the selection according to predefined command ordering rules. The command ordering rules are command type dependent.

Abstract: An interrupt handling technique is provided that may allow for sharing level sensitive interrupts in systems where interrupts are message based, i.e., edge triggered. An interrupt input unit is provided for receiving level sensitive interrupt requests and generating request occurrence signals therefrom. An edge detection unit generates start signals for edge triggered interrupt messages on the basis of the request occurrence signals. An interrupt termination detection unit receives termination signals each indicating that an interrupt routine relating to a previous edge triggered interrupt message has terminated. The interrupt input unit is controlled to output a request occurrence signal in response to a received termination signal if a previously received level sensitive interrupt request is still active. That is, a second edge triggered interrupt message may be generated.

The host controller comprises a buffer unit for buffering data and a data stream selection unit for selecting a data stream for submission to the buffer unit. The data stream selection unit is connected to receive at any one time at least one of a host-to-device data stream in the PIO data transfer mode, a host-to-device data stream in the DMA data transfer mode, a device-to-host data stream in the PIO data transfer mode, and a device-to-host data stream in the DMA data transfer mode, and select from the received data streams the data stream to be submitted to the buffer unit.

Abstract: A method an apparatus for providing capability information to a shared controller. In one embodiment, a peripheral bus host controller may be shared by a plurality of peripheral devices coupled to a peripheral bus. The peripheral devices may include coder/decoder (codec) circuitry, and may be implemented using a riser card. The host controller may be configured to query the bus for peripheral devices by reading each address on the bus. During the querying process, the host controller may detect one or more peripheral devices coupled to the bus. Following the completion of the querying of the bus, the host controller may then begin reading configuration information from each of the detected devices. The host controller may employ one or more of several different techniques in order to read configuration information from the peripheral device. The configuration information at a minimum includes a device identifier, which may identify the vendor and the function of the device.

Abstract: An integrated circuit chip, particularly a southbridge, is provided that has a first and a second circuit unit. Each circuit unit can send requests to the other one and send back a response when receiving a request that requires a response. The first circuit unit can store data relating to a request to be sent, and the second circuit unit cannot store data relating to a received request. Thus, an on-chip interface is provided that may increase the overall system performance and that may support split transaction.

The instruction register is arranged to store a one-hot encoded instruction identifying one of the Boundary Scan test modes. The Boundary Scan register is further arranged to extract which test to perform on the tested part of the circuitry from the one-hot encoded instruction stored in the instruction register. The integrated circuit chip and corresponding methods and hardware devices may benefit from increased test flexibility and reduced time to market.

Abstract: An improved interface technology is provided that may be applied to PCI (Peripheral Component Interconnect) devices connected to a southbridge. Requests are received from at least one requestor. The request require responses to be sent back to the respective requestor. The requests are placed by the respective requestor by asserting a request signal, and the request signal is deasserted by the respective requestor when a response is sent back. A retry request may be sent to the current requestor for requesting the current requestor to deassert its request signal although a response has not yet been sent back, and to reassert the request signal later. Together with the retry request, a ready signal is sent indicating whether the request could be processed. This allows the requestor to modify its request when retrying it, if the request was not yet processed.
