FPGA-based ultrasonic detection data storage module and FPGA circuit

Abstract

The invention relates to an ultrasonic detection data storage module and an FPGA circuit based on an FPGA, comprising a main module, a storage module, a write address module and a read address module.The main module is used for calling the memory module, writing the address module and reading the address module, and realizing the digital logic of the readable flag and the alarm flag. The memory module adopts a segmented management of a memory, through writing, zeroing and replicating, thus avoiding switching between multiple memories to achieve the same scheme. And through the introduction ofalarm signs, notify the detection personnel to take relevant measures to avoid data overflow data loss or signal loss and other problems. According to the common requirements of ultrasonic testing application, the interface signal, sign signal and alarm signal of the module are designed to simplify the secondary development process of users.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to an FPGA-based ultrasonic detection data storage module and FPGA circuit. Background technique [0002] At present, there is an FPGA-based data caching method based on asynchronous double FIFO implementation. This method is applied in the field of ultrasonic testing and can increase the repetition rate of the system. In specific applications, complex logic design is required to switch control signals and data input and output signals between the two memories, which increases the difficulty of secondary development. In high-frequency applications, the timing requirements are high; the signal interface of this method Based on the standard FIFO signal interface, it is necessary to customize the peripheral logic according to the project requirements when applying ultrasonic testing. But there is no strategy for the proposed method when data overflows. [0003] Another caching sys...
