Abstract: An illegal address mask method for cores of a DSP includes: S1, initializing a core of a DSP; S2, configuring a start address register and an end address register, and taking an address range defined by the start address register and the end address register as a masked address range; configuring a first comparator and a second comparator to send out illegal address decision signals for instructions within the masked address range; S3, acquiring a PC pointer, and determining whether the PC pointer is located in the masked address range; if so, sending out an illegal address decision signal to stop an operation; if not, performing pre-decoding to obtain a memory access instruction; and S4, determining whether an address of the memory access instruction is located in the masked address range; if so, sending out an illegal address decision signal to stop an operation; otherwise, completing a memory access operation.

Abstract: A two-sided time-sharing driving and acquisition system based on dry contacts comprises k dry contacts, a processor, p acquisition circuits, and m driving circuits. The p acquisition circuits are evenly divided into two groups which are separately disposed at two sides of the k dry contacts. The m driving circuits are separately disposed at the two sides of the k dry contacts. A system fault detection method and the two-sided time-sharing driving and acquisition system have the following advantages: the state of input acquisition circuits and cables monitored in real time during system debugging or running, and faults caused by exceptions of the acquisition circuits and the cables can be reported in time.

Abstract: A holding mechanism comprising a holding base, having two oppositely arranged holding grippers with at least one of the two holding grippers being movable. A first resilient biasing member, disposed between the holding base and the movable holding gripper, exerts an elastic biasing force on the movable holding gripper to cause the movable holding gripper to have a tendency to return to its initial position. The holding mechanism includes a locking structure and an unlocking component respectively provided on the holding base. The movable holding gripper moves to a trigger position away from the other holding gripper, and the locking structure locks the movable holding gripper when reaching the trigger position to block the movable holding gripper from returning to its initial position. The unlocking component unlocks the locking structure to remove the blockage of the locking structure to the movable holding gripper.

Abstract: Particles of a macro-porous ion exchange resin are dispersed in a solution of a transition metal compound, such as a compound of molybdenum, tungsten, or vanadium. The resin may be composed for anion exchange or cation ion exchange and, correspondingly, anions or cations of the metal are exchanged onto active ion exchange sites on the molecular chains of the resin. The resin is then carbonized and graphitized to form nanometer-size particles of transition metal carbide on particles of graphite. The composite metal carbide and graphite particles are electrically conductive and serve well as support particles for later deposited particles of a platinum group metal or other catalyst material in, for example, a catalytic electrode member in an electrochemical cell.
