Problems solved by technology

Each addition needs three beats, and due to the use of external memory, when the system clock is a high-speed clock such as 100MHz, each beat needs several clock cycles to complete, and the accumulation speed is very slow, usually up to 60ns or more at a time, and less efficient

Abstract

The invention discloses a novel data acquisition accumulator and an implementation method thereof. The novel data acquisition accumulator comprises a data input module used for converting analog signals into digital signals and a field programmable gate array module used for acquiring the digital signals output by the data input module and accumulating and summing the acquired data. The inventionutilizes rich resources of the interior of the large scale integrated circuit and the high speed parallel processing capacity thereof, adopts the method of pipelined acquisition and accumulation, simplifies the hardware circuit structure of the data acquisition accumulator, and improves the speed of accumulation.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and relates to a novel data acquisition accumulator and its realization method. Background technique [0002] In the application of optical fiber sensing, since the scattering signal is very weak and completely submerged in the noise, the system needs to use weak signal detection to extract the signal to be tested from the noise. Taking the fiber optic temperature measurement system as an example, the main components of the noise in the system have the statistical characteristics of zero mean value, and the statistical characteristics of the noise can be used to achieve the purpose of noise reduction. Therefore, in order to improve the signal-to-noise ratio, the follow-up signal processing adopts the method of digital averaging, that is, the N-point data of one measurement are stored in the memory unit in turn, and the N-point data of the next measurement are added to the data of the ...
