Abstract

The invention relates to the technical field of computer application and discloses an information fixed-point processing device. The information fixed-point processing device comprises an output controller, a plurality of groups of fixed-point processing cores which are connected in series, and corresponding interconnection interfaces, wherein the fixed-point processing cores control functional modules, which process data information, are connected with the interconnection interfaces and transmit fixed-point processing information at the same time; the interconnection interfaces are connectedwith the fixed-point processing cores and different functional modules and transmit data and the fixed-point processing information among modules; and the output controller is connected with the interconnection interfaces and receives the output data and the fixed-point processing information for detecting precision and determining to output the results or continue the processing after a processing formula is corrected. The information fixed-point processing device has higher processing efficiency and processing precision.

Description

technical field [0001] The present invention relates to a device and a processing method in the field of computer application technology, in particular to an information fixed-point processing device with automatic processing capability and a processing method thereof. Background technique [0002] For reasons of low power consumption, low cost, and ease of design, many processing units do not support floating-point operations. But this also limits the operations that the processing unit can undertake, because the operands must be integers. The usual solution is that if the source operand is a floating-point number, fixed-point processing is required to convert the floating-point number into a fixed-point number. The so-called fixed-point operation is to first shift the data to the left and round it up, enlarge it, and then perform the operation and then shift it to the right to reduce it to the correct order of magnitude. The following formula describes the fixed-point pr...
