Abstract:
State of the art processor systems, esp. in embedded systems, are not able to process data under real-time conditions especially with throughput rates near 10 Gbps. So, when using interfaces like PCI Express (PCIe) or Infiniband or 10 G-Ethernet for 10 Gbps data throughput, special data-paths have to process the high throughput rate data. But tasks like connection management or time uncritical control messaging are better manageable by a processor. According to the invention it is proposed a kind of multiplexer architecture that is needed to split between control and data-path access for a PCI Express based architecture.
Abstract:
Two or more electronic devices are connected via a bus system building a cluster or chain of devices. A device can be selected using a control device, wherein an user interface for the selected device is generated based on description data which are stored in the selected device and are transferred to the control device. A single user interface is shown on a display of the control device which allows to operate at least two devices simultaneously. The user interface of a first device is displayed as main user interface and the user interface of a second device is rendered within the main interface as reduced user interface which includes only operation elements necessary for operation of the second device in combination with the first device.
Abstract:
The invention concerns a solid state memory, comprising multiple logical units. The solid state memory contains an internal buffer for temporarily storing the incoming data steam before the incoming data are programmed to at least one page. The internal buffer keeps data that are not yet programmed in case a switch from one logical unit to another is performed. A method for operating such a device is presented.
Abstract:
The present invention relates to a memory controller for an IC with an external DRAM, where the external DRAM has at least one memory bank and communicates with the IC via at least one channel. In line with the invention, the memory controller has a command scheduler which prioritizes the transmission of memory bank commands on the basis of a static priority allocation for commands and a dynamic priority allocation for channels.
Abstract:
For writing, flash memory devices are physically accessed in a page-oriented mode, but such devices are not error-free in operation. According to the invention, when writing information data in a bus write cycle in a sequential manner into flash memory devices assigned to a common data bus, at least one of said flash memory devices is not fed for storage with a current section of said information data. In case an error is occurring while writing a current information data section into a page of a current one of said flash memory devices, said current information data section is written into a non-flash memory. During the following bus write cycle, while the flash memory device containing that defective page is normally idle, that idle time period is used for copying the corresponding stored section of said information data from said non-flash memory to a non-defect page of that flash memory device.
Abstract:
For recording or replaying in real-time digital high bandwidth video signals, e.g. HDTV, HD progressive or HD film capture signals, very fast memories are required. For storage of streaming HD video data NAND FLASH memory based systems could be used. Flash memory devices are physically accessed in a page oriented mode. According to the invention, the input data are written in a multiplexed fashion into a matrix of multiple flash devices. A list processing is performed that is as simple and fast as possible, and defect pages of flash blocks of single flash devices are addressed within the matrix architecture. When writing in a sequential manner, the data content for the current flash device page of all flash devices of the matrix is copied to a corresponding storage area in an additional memory buffer. After the current series of pages has been written without error into the flash devices, the corresponding storage area in an additional memory buffer is enabled for overwriting with following page data. In case an error occurred in the current page in one or more flash devices, the content of these current pages is kept in the additional memory buffer.
Abstract:
The invention relates to a method for synchronizing a transmitter memory area in a transmitter memory in a transmitter apparatus with a receiver memory area in a receiver memory in a receiver apparatus, and to a receiver apparatus. The transmitter memory area stores transmission data as transmission-data packets and the receiver memory area stores received data as received-data packets with associated error status data which respectively indicate an error status for the received-data packets. Before a reference identification is generated in the receiver apparatus, which, following transmission using a feedback message in the transmitter apparatus, is used for memory area synchronization, the error status data for a plurality of the received-data packets are checked in the receiver apparatus until a first received-data packet is ascertained for which the error status data indicate no error status. An identification which identifies the first received-data packet is used to ascertain an identification for the current reference received-data packet taking into account a predetermined formation rule for forming the identifications for the received-data packets, from which identification the reference identification for the current reference received-data packet is derived.
Abstract:
Method for fast verification of sector addresses The present invention relates to a method and a device for the fast verification of sector addresses (9) in a data stream (2) obtained from a recording medium (1) upon a request from a microcontroller (13). According to the invention, the method comprises the steps of: reading the data stream (2) from the recording medium (1); decoding the data stream (2) to obtain a decoded data stream comprising user data (6) and sector addresses (9); comparing the sector addresses (9) with a range (12) of valid sector addresses; and transmitting only user data (8) having sector addresses (9) within the range (12) of valid sector addresses; whereby dedicated comparing means (10) are provided for performing the comparing step independently of the microcontroller (13).
Abstract:
The invention concerns a 1. Method for interfacing communication between a first device on a first network and a second device on a second network, the networks being connected by an interface device, the method being carried out by the interface device and being characterized by the steps of: detecting a first message on the first network, said first message being generated by the first device, said first message being relevant for the second device; translating the first message into a format compatible with the second device; sending a second message to the second device on the second network, the second message informing the second device that the first message has been detected; upon reception of a request from the second device, transmitting the translated first message. The invention also concerns a device for implementing the method.
