The invention relates to the technical field of PCB, and discloses a PCB connecting and fixing device comprising a main PCB and an auxiliary PCB. The surface of the main PCB is provided with installing holes. Fixing devices are fixedly connected on the surface of the main PCB. A fixing plate is fixedly connected on one side of the main PCB. Rotating shafts are fixedly installed on the surface of the fixing plate. A clamp block is fixedly connected on the surface of each rotating shaft. A connecting plate is fixedly connected on one side, which is close to the main PCB, of the auxiliary PCB. The contact surface of the connecting plate and the fixing plate is provided with an auxiliary groove. According to the PCB connecting and fixing device, a convex block, the auxiliary groove and a sealing ring are arranged, the convex block and the auxiliary groove are mutually clamped when the clamp blocks and clamp grooves are mutually and adaptively clamped, the sealing ring deforms a lot under compression because of the hollow structure of the sealing ring, and the two sides of the sealing ring extend to the external side and contact the internal wall of the auxiliary groove in a sealing wayso that the sealing performance of the connecting part of the main PCB and the auxiliary PCB can be enhanced and the objectives of stable connection and convenient installation can be achieved.

Under the support of a chip ejector (6), a semiconductor chip (1) is separated from a foil (4), and the semiconductor chip (1) is picked up from the foil (4). The chip ejector (6) is provided with an incline (16) and a support area (13) which is provided with a groove (12) arranged close to a stripping edge (18). A surface (17) of the incline (16) is a concave and is stopped at the stripping edge (18) which is protrudent from the surface (9) of the chip ejector (6). The groove (12) can be vacuumized. The separation and picking-up of the semiconductor chip (1) and the foil (4) are generated by the relative movement of a wafer platform (5) towards the chip ejector (6), so as to be convenient for the stripping edge (18) protruding from the surface (9) of the chip ejector to pull the foil (4), accordingly the semiconductor chip (1) is at least partially separated from the foil (4) temporarily by self and lands at the foil (4) above the support area (13), and a chip gripper (7) picks up the semiconductor chip (1) placed at the support area (13).

The invention discloses an optimization method for a resistive variable memory with a crossbar structure, and belongs to the technical field of computer storage. The method of the present invention designs voltage sources at the four terminals of each crossbar array, alleviates the problem of voltage drop on word lines and bit lines at the same time, divides the array into three types of fast, medium, and slow blocks, and maps thermal data to Fast blocks, map warm data to medium blocks, map cold data to slow blocks, and also explore the relationship between block types, RESET delays, and the proportion of low-resistance cells on selected word lines, and map the most appropriate RESET The delay is exposed to the memory controller call, dynamically accelerates the RESET operation, and a solution combining circuit and architecture is designed to solve the problem of read and write interference, thereby optimizing the performance and reliability of ReRAM.

The computing device determines that a current software thread of the plurality of software threads having an issue sequence is not waiting for a first instruction to be issued to a hardware thread during one clock cycle. The computing device identifies one or more alternate software threads in the issue sequence that have instructions waiting to be issued. The computing device selects, during the clock cycle, the second instruction from a second software thread among the one or more alternate software threads having no dependencies on any other instruction among the instructions waiting to be issued. Second instruction. Dependencies are identified in terms of the value of the link bit extracted from each instruction waiting to be issued. The computing device issues a second instruction to a hardware thread.
