This invention relates to the field of integrated circuits and discloses a mixed-precision in-memory computing circuit, data processing method, and chip. The invention includes: a storage array, an index memory, and a multiply-accumulate calculation circuit. The storage array includes a first data element stored in a first precision format and / or a second data element stored in a second precision format; wherein the bit width of the first precision format is greater than that of the second precision format; the storage locations of the storage array are divided according to the bit width of the second precision format; the first data element occupies multiple consecutive storage locations; the read bit width of the storage array is an integer multiple of the bit width of the first precision format; the index memory stores the position index information of the first data element in the storage array; the multiply-accumulate calculation circuit is used to determine the precision format corresponding to the data read from the storage array based on the position index information, and performs a multiply-accumulate operation corresponding to the precision format, outputting the calculation result. This solves the compatibility problem between mixed-precision data storage and computing circuits.

Automatic conveying structure of chain type paper bill printer
InactiveCN119189519Areduce rotation speedeasy to transportOther printing apparatusComputer printingStructural engineering
The invention provides an automatic conveying structure of a chain type paper bill printer, and relates to the technical field of printers, the automatic conveying structure comprises a printer main body, a fixed frame of an inverted U-shaped structure is fixedly installed above the inlet end of the printer main body, and a device box is installed on the surface of the right end of the fixed frame; the left and right ends of the inlet end of the printer body are respectively provided with a connecting block. According to the device, the pull rod is pulled outwards, at the moment, the limiting cover plate is separated from the fixed gear, the limiting cover plate loses the limiting effect on the fixed gear, a worker can adjust the inclination angle of the containing plate according to needs, after adjustment is completed, the limiting cover plate can be connected to the exterior of the fixed gear in a sleeving mode again only by loosening the pull rod, and the fixing gear can be fixed. The problems that printed bills are irregular due to the fact that chain-type paper is prone to deflection during continuous advancing, and an existing containing plate used for containing bill paper is fixed to a printer body, and the inclination angle of the containing plate cannot be adjusted are solved.

A slitting and conveying device and a conveying method for F46 film production
The invention relates to the technical field of film slitting, and discloses a slitting conveying device and a conveying method for F46 film production. The film is conveyed to a slitting tool, the slitting tool performs slitting processing on the film, and the slitting film is rolled onto a winding roller. When the current winding roller is wound, a new winding roller is replaced, and the clamping arm is started. The clamping arm clamps and fixes the head end of the film after the slitting processing, and then the clamping arm drives the head end of the film after the slitting processing to move along an upper positioning guide rail (lower positioning guide rail), so that the clamping arm winds the head end of the film after the slitting processing onto a new winding roller, so that the head end of the film after the slitting processing is neatly rolled onto the new winding roller, so that the head ends of each film after the slitting are neatly rewound onto the new winding roller, so as to avoid the occurrence of wrinkles and other problems when the current winding roller is wound, and the neatness of the rewound slitting film is ensured, the quality of the wound film is ensured, and the stability of the device operation is improved.
