The invention discloses a method and a device for automatically matching and upgrading a CPLD of a service board card, and relates to the technical field of communication. The method comprises the steps of storing CPLD target code universal versions and CPLD target code special versions of all service single disks are in a disk control module; after the service single disk is started, judging whether single disk type information can be obtained through the CPLD or not, and if the single disk type information cannot be obtained, burning a CPLD target code general version into the CPLD on line through an upgrading interface; and if the single disk type information can be obtained, obtaining upgrading information of the special version through the CPLD, matching the single disk type information with the stored special version of the CPLD target code after determining that upgrading is needed according to the upgrading information, and calling an upgrading interface to burn the matched special version of the CPLD target code into the CPLD on line. According to the invention, the production efficiency of the single disk is improved, the consumption of I / O resources of the disk control module is reduced, the management and maintenance of the disk control single disk and versions are facilitated, and the actual application requirements are met.

The invention discloses a device and a method for testing a system-on-chip chip with a plurality of isomorphic IP cores. The device comprises a controller and a condition comparator, wherein the controller is provided with a plurality of control signal interfaces connected to each corresponding isomorphic IP core and is used for inputting a test control signal to each isomorphic IP core, controlling the test on one or more isomorphic IP cores, broadcasting the same test excitation data to the IP cores and simultaneously controlling the output of a test response of a certain IP core; the test response serves as a reference test response and is compared with the test responses of other IP cores; and the condition comparator is used for comparing the test response of a corresponding IP core with the reference test response and processing the comparison result to produce a one-bit error identification signal for identifying whether the comparison is accordant.

The invention belongs to the field of embedded systems, and discloses a dual-port peripheral configuration interface circuit. According to the interface circuit, only two IO interfaces are provided externally, one is an RCK (read clock) input port, and the other is an RDA (remote data access) data two-way port. A read-write data port, a read / write address signal port, and a read-write enable signal port are connected with a register set. The interface circuit comprises a clock counter, a read-write judging register, an address / data shifting register, a read data shifting register, an address register, a write enable signal generation register and a read enable signal generation register. The interface circuit disclosed by the invention has the advantages that the communication protocol and the circuit are simple, external ports are few, the communication speed changes with the rate change of an externally supplied RCK clock, an externally supplied system clock is not needed, and the like.

The invention relates to a configurable low-speed PAD and a BMC chip possessing an intelligent reconfigurable interface. The chip is characterized in that the chip includes an ARM; the ARM is connected to the configurable low-speed PADs, low-speed PADs and high-speed PADs; the ARM is connected to an interface control logic module; the interface control logic module is connected to the configurable low-speed PADs, the low-speed PADs and the high-speed PADs; the configurable low-speed PADs, the low-speed PADs and the high-speed PADs are connected to an BMC chip pin respectively; and there are the several configurable low-speed PADs, the several low-speed PADs and the several high-speed PADs. In the invention, the configurable low-speed PADs are designed, open drain output and normal output functions are possessed, and a pull-up resistor function under an I2C mode is possessed too. After the BMC chip is molded, the interface can be intelligently configured and great convenience is brought for a board-grade design. IO resources can be saved, and interface reuse of the BMC chip to 12C, SPI and PCIE is realized.

The invention relates to multimedia storage method, system and device. The multimedia storage method comprises the following steps: acquiring a user recording program list and recording document information of the recorded multimedia contents; judging whether to accept or reject the recorded multimedia contents according to the user recording program list and the recording document information, saving necessary recording documents in the recorded multimedia contents according to the result of the judgment, and deleting unnecessary recording documents in the recorded multimedia contents. The user recording program list is used for providing time shifting service or / and review service. The technical scheme can share one recording document in a time shifting and review mode, reduce the IO resources by writing and storing with one media server, double the recording performance of the media server and also reduce the storage space waste of the recorded contents of the time shifting programs.

The invention discloses a method and a server for secondary confirmation short messaging. The method for secondary confirmation short messaging comprises the following steps: receiving a short message request message sent by a client, wherein the short message request message includes uplink object information; determining a client instruction corresponding to the short message request message based on the uplink object information in the short message request message; querying a table entry matched with the client instruction in a service instruction table, and determining whether the short message request message needs secondary confirmation based on the queried table entry matched with the client instruction; storing the uplink object information in a memory and sending a secondary confirmation short message to the client when determining that the short message request message needs secondary confirmation; querying uplink object information corresponding to a first confirmation short message in the memory when receiving the first confirmation short message sent by the client; and executing queried service associated with the uplink object information. By adopting the technical scheme of the invention, the efficiency processing of secondary confirmation short messages can be improved.
