streaming data and axi interface communication device

Abstract

The invention discloses a communication device between stream data and AXI interface, comprising a transmission control module, a FIFO module, an interface communication module and a status signal storage register; the transmission control module is responsible for receiving a signal to start a collection of a host computer, monitoring the amount of DDR data, and controlling the collection of data Stored in DDR; the FIFO module is used to convert the data rate of the collected data and buffer the data to organize an AXI burst write; the interface communication module reads the data from the FIFO and encapsulates it into the data format specified in the AXI4 protocol. Then write it into the DDR memory; the state signal storage register is used to store the start acquisition control signal sent by the host computer software, and the DDR memory to store the data amount status signal. The invention supports the mapping of the master-side stream data into the address space of any size of the slave-side, improves the PCIE data transmission rate, supports user-defined settings, and has strong compatibility.

Description

technical field [0001] The invention relates to data collection and transmission technology, in particular to a communication device for stream data and AXI interface. Background technique [0002] With the rapid development of information technology, the amount of data processed by people has also increased significantly. Data transmission is an important part of data processing, and people have higher and higher requirements for data transmission speed. Society plays an important role. [0003] As the third-generation high-performance I / O bus, PCIE has changed from a parallel bus to a serial bus compared with the previous generation PCI bus, and uses high-speed differential signals to reduce bus signals and greatly increase the transmission rate. Existing high-speed data transmission systems are mostly based on PCIE1.0, PCIE2.0, USB3.0, Gigabit Ethernet ports, etc., but their transmission rate still cannot meet the data transmission rate requirements of modern radar echo ...
