A computing circuit, oscilloscope and measuring instrument based on fpga

Abstract

The invention discloses an operation circuit based on an FPGA (Field Programmable Gate Array), an oscilloscope and a measuring instrument. An output interconnected matrix module is used for taking an operation result outputted by a first operation module as an input quantity of a second operation module and the operation result outputted by a third operation module as a final output; the operation result outputting by the first operation module is served as an the input quantity of other operation modules; the second operation module is an operation module in which the input quantity is served as the operation result outputted by the other operation modules; the third operation module is an operation module in which the outputted operation result is served as the final operation output quantity of the operation module; a same operation module can be served as the first operation module, the second operation module and the third operation module under different operation processes; the multi-level random interconnection between the operation modules can be ensured; the detaching times of the arithmetical operation is reduced, so that the arithmetical operation speed is increased; the parallel characteristics of FPGA have no influence on the other operations of the system in an operation process, so that the condition of system blocking is avoided.

Description

technical field [0001] This application relates to the field of data processing, more specifically, to an FPGA-based computing circuit, an oscilloscope and a measuring instrument. Background technique [0002] The mathematical operation device is one of the functional units of most measuring instruments, which is used to complete mathematical operations. The traditional mathematical operation device is realized by a microprocessor. The structure is as follows: figure 1 As shown, when performing mathematical operations, it is necessary to fetch instructions from the program memory to control the operation unit to obtain data from the data memory for operation, and to control the operation results of the operation unit to be stored in the data memory. [0003] The mathematical operation model can be summarized as y=f[g 1 (x 1 ,x 2 ,...,x n ), g 2 (x 1 ,x 2 ,...,x n ),…, g k (x 1 ,x 2 ,...,x n )], where g 1 … g k is a sub-function, that is, the operation function ...

Problems solved by technology

The way the microprocessor performs mathematical operations is based on the serial operation of the instruction set, which requires multiple iterations, is slow, and has a single structure, which takes up a lot of microprocessor resources during operations, which can easily lead to system freeze failures.
