Embodiment Construction

[0056] The digital engineering method of mixed number system and carry-on written calculation is also called "three-Q written calculation engineering method". It belongs to one of the collectively called "three Q methods". The present invention belongs to the category of "method" inventions. For this reason, this part is described with corresponding technical features such as "operating conditions and steps" and "data flow".

[0057] 1. The digital engineering method of mixed-number system and carry-on writing calculation adopts "mixed-number system" and "mixed-number system and carry-on method" for calculation. figure 1 It is a logical block diagram of the mixed number base and carry calculation project. It includes: input register network 101 ; input digital converter network 102 ; mixed number system operator 103 ; output digital converter 104 ; output register 105 . (attached figure 1 The logic block diagram of the mixed number base and carry line calculation project. ...

Abstract

The invention relates to the field of digital engineering methods and written calculation engineering and provides a new digital engineering method. The written calculation engineering for overall design based on a mixed digital scale and carry bit row written calculation digital engineering method can obviously improve the operating rate of the written calculation engineering and greatly lower the error rate of written calculation. The method comprises the following steps of: converting K input general Q scale numbers for adding and subtracting into K or 2K mixed digital scale numbers; then, carrying out mixed digital scale summation on the K or 2K mixed digital binary numbers; carrying out addition without carry from the lowest bit or simultaneously on all bits and storing a bitwise sum number into a next operation layer; meanwhile, storing the obtained mixed digital scale into the next operation layer or a high-order vacant bit adjacent to any data row or 0-bit, which are not operated in the current operation layer; repeatedly operating in such a way until no carry bit is generated in the operation layer after the operation; and finally outputting the number which is the addition sum of the operated mixed digital scale.

Description

technical field [0001] The invention relates to the fields of digital engineering methods and written calculation engineering Background technique [0002] Digital engineering includes CNC machine tools, digital equipment and digital system engineering, etc. "Digital engineering" in the present invention refers specifically to "digital computing system engineering". It is not to solve specific calculation problems, or theorem proofs, or geometric problems, or some kind of mathematical ideas, but to solve the digital engineering implementation technical solutions of the computing system itself such as the four algorithms. It is closely related to specific computing tools. As we all know, there are many kinds of "calculation", except for "approximate calculation", "simulation calculation" and "toolless calculation" (mental calculation, finger calculation, oral calculation, etc., including corresponding formulas, quick calculation, and estimation), it is "using tools". digit...
