A substrate clamp includes a bar supporter having a end for connecting and fixing a substrate bearing apparatus; an arm extending from another end of the bar supporter and profiling an angle with the side wall of the bar supporter; and a buffer layer arranged on the side wall of the bar supporter. The present substrate clamp can effectively decrease the split problem of the glass substrate causing from the shocking and sliding in the clamping or moving of the manufacturing processes and enhance the product yield.

A communication terminal device having an image memory (21) which does not overflow even if it accepts data during an interrupted condition. When an interruption key (14) on an operation panel (13) is pressed, the communication terminal device enters an interrupt condition. During the interrupt condition, the device receives data through its NCU (19) and modem (20) and stores it in the image memory. If a user inputs no instructions to the device from the operation panel (13) for a predetermined period during the interrupt condition, a printer (16) is caused to print the image stored in the image memory (21). Thus, the image memory has a room for newly coming data, and does not overflow. If the interrupt process needs to use the printer (16), the printing by the printer is stopped, and the interrupt process is given priority.

The invention discloses an instruction processing device. The instruction processing device comprises: a first register suitable for storing first source data; a second register adapted to store second source data; a third register suitable for storing accumulated data; a decoder suitable for receiving multiply-accumulate instructions and decoding the multiply-accumulate instructions; and an execution unit. The multiply-accumulate instruction indicates that the first register is used as a first operand, the second register is used as a second operand, and the third register is used as a thirdoperand and a shift identifier. The execution unit is coupled to the first register, the second register, the third register and the decoder, executs the decoded multiply-accumulate instruction for obtaining first source data from the first register, and acquiring second source data from a second register, performing multiplication on the first source data and the second source data to obtain a multiplication result, shifting the multiplication result according to the shifting identifier, and adding the shifted multiplication result to accumulated data in a third register to obtain a multiply-accumulate result. The invention further discloses a corresponding instruction processing method, a computing system and a system on chip.

The invention provides an FPGA implementation method and system of a FARROW type filter. The FPGA implementation method of the FARROW type filter comprises the following steps that S1, quantizing filter coefficients of the FARROW type filter; S2, carrying out multiplication and accumulation operation according to an interpolation base point generated during error interval calculation and the quantized filter coefficient; and S3, performing multiplication and addition operation on the result after the multiplication and accumulation operation and the calculated error interval. Error intervals and interpolation base points are generated in real time, and a large number of ROM resources which are not used in the FPGA implementation process of the FARROW type filter are reduced; On the basis,only one time of quantization of the filter coefficient is needed, equivalently, under the condition of the same quantization bit width, the error of amplitude-frequency response is smaller, and the possibility of overflowing is effectively reduced.

The invention relates to a concrete powder storage device, and belongs to the technical field of concrete powder tanks. The concrete powder storage device comprises a powder tank, a feeding pipe fixed on the peripheral surface of the powder tank and a material collecting box fixed at the bottom end of the feeding pipe, a cover plate is hinged to the side wall of the material collecting box, a connecting rod is hinged to one side of the cover plate, a sliding block is hinged to the end, away from the cover plate, of the connecting rod, and the sliding block is in sliding connection with the side wall of the material collecting box in the vertical direction; a first spring is fixed to the top end of the sliding block, a first connecting piece is fixed to the side, away from an exhaust pump, of the material collecting box, and the top end of the first spring is fixedly connected with the bottom face of the first connecting piece; the side wall of the material collecting box is slidably connected with a limiting piece in the width direction of the material collecting box; the side, away from the cover plate, of the sliding block is provided with an inserting groove used for being connected with the limiting piece in an inserted manner; and the side wall of the material collecting box is provided with a releasing assembly used for releasing limiting to the sliding block. The concrete powder storage device has the advantage that the situation that powder in the material collecting box is prone to overflowing is reduced.
