Embodiment

[0033] Such as figure 1 As shown in the figure, the collector, processor A, processor B, and SRIO switch board are connected through the 6UVPX backplane. The SRIO switch board, collector, and processor are inserted into the system side by side, and processor space is reserved in the system. The collector is the sender, which can simultaneously support 8-channel HD-SDI and 4-channel PAL concurrent acquisition at the same time. According to the control command word, it selects an active or passive way to start collecting video data. The processor is the receiver, which can be configured according to system requirements. Single or multiple processors, this system uses the configuration of processor A and processor B as an example for illustration. The SRIO switch board can be set to unicast or multicast to share video data.

[0034] Figure 2a The shown collector uses SWRITE to actively send data to the register address space of the receiving end, and adds a doorbell message to...

Abstract

The invention provides a multi-source image sharing system based on high-speed data exchange, and the system comprises a collector, a processor, an SRIO exchange board and data sharing software running in the system; the collector, the processor and the SRIO exchange board are connected through a 6UVPX backboard, and the collector and the processor are in SRIO high-speed interconnection through the SRIO exchange board. The collector is a source end of the system and can concurrently support simultaneous collection of 8 paths of HD-SDI and 4 paths of PAL, the data sharing mode of the system can be configured to be active or passive according to application requirements, the processor is an operation center of the system, one or more processors can be configured according to the system requirements, the processors can be subjected to cascade processing or parallel processing, the SRIO switching board is a transmission medium of the system, and the switching mode can be set to be unicast or multicast.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to a multi-source image sharing system based on high-speed data exchange. Background technique [0002] With the development of science and technology and the improvement of data processing capabilities, scientific research experiments and industrial production are more dependent on image data. Common high-speed serial buses include RapidIO, PCI Express, and Gigabit Ethernet. In terms of topology, RapidIO and Ethernet buses are both fuzzy topological structures. Any endpoint group can be connected with any topology. PCIExpress supports a single root complex. Tree. In terms of transmission bandwidth, all three support different bandwidth option functions, but compared with Ethernet, PCI Express and RapidIO support more combinations of channel speed and channel bandwidth. In terms of reliability, all three have bit error detection and reminder mechanisms, but the bit error detection ...
