PCIE (peripheral component interconnect express) based radar data acquisition displaying and controlling system and method thereof

Abstract

The invention discloses a PCIE (peripheral component interconnect express) based radar data acquisition displaying and controlling system and a method thereof. The PCIE based radar data acquisition displaying and controlling system comprises an upper computer module, a PCIE interface module, an FPGA (field programmable gate array) control module, an AD acquisition module and a storage module. The upper computer module is used for setting and processing parameters, sending and processing information and displaying images. The PCIE interface module is used for sending information and transmitting data between the upper computer module and the FPGA control module. The FPGA control module completes receiving and transmitting of the data and is responsible for controlling the modules. The AD acquisition module completes data acquisition. The storage module is used for storing the data. The method includes that the acquired data are transmitted to the upper computer module by means of a TLP (thread-level parallelism) data package and then drawn into an image to be displayed on a screen by means of a double buffer technique by the upper computer module according to set displaying parameters. The PCIE based radar data acquisition displaying and controlling system and the method thereof reduce system cost, increase data transmission rate and can be applied to a radar data acquisition system, particularly a system high in data transmission rate and strong in instantaneity.

Description

technical field [0001] The present invention belongs to the technical field of communication, and further relates to a radar data acquisition and display control system and a method thereof based on a Peripheral Component Interconnect Express (PCIE) in the technical field of digital signal processing.

Its large amount of data and str...

AI Technical Summary

Problems solved by technology

But, the deficiency that this system and method exists is, the first, because the data transmission rate of PCI bus line is theoretically up to 132MB / S, can not satisfy high-speed data transmission, increases system overhead

Second, the data is transmitted in a compressed manner, which cannot meet the requirements of large data transmission, the efficiency is low, and the error rate of data transmission is high

Third, the host user record implementation adopts single task and single thread, the power consumption of the system is high, the system utilization rate is low, and the processing capacity is poor

Fourth, because the host only has user records, the module has a single function, and the operability and intuition are poor
