The invention provides a method for generating afterglow of a spectrum analyzer and the spectrum analyzer. The method includes: performing quadrature mixing processing on an input signal of the spectrum analyzer to obtain a complex baseband signal; performing FFT calculation on the complex baseband signal to generate FFT calculation result data; Preset integers G and P, with G times of FFT calculation results as a group, and P pieces of FFT calculation data in each FFT calculation result as one piece, the FFT calculation result data is divided into A group and B slice; for each FFT calculation result Perform display interpolation processing on the data; perform histogram statistical accumulation on the display interpolation processing results of each group in the same slice, and generate the histogram statistics of the FFT calculation result data of each slice; according to the predefined color mapping value and the histogram of each slice within the afterglow time Graph statistics generate persistence display images. The invention performs grouping and fragmentation processing on FFT calculation data, fully utilizes the characteristic of high bandwidth efficiency during sequential access of DRAM, and completes a large number of calculations of display interpolation in a relatively short time.

The invention discloses a method for storing a plurality of data in SDRAM, which comprises the following steps: each part of data is divided into a plurality of data blocks with the same size, the size of each data block is equal to the length of BURST which is used for reading the SDRAM internal storage data, and the data blocks of adjacent presetting part date are sequentially staggered and stored into a storing unit of an SDRAM storing array. In the method, the storing positions of the storing data in the SDRAM are arrayed, so the storage data in a SOC system which has larger probability of the concurrent access of a plurality of data packets by the similar offset in each MASTER can be more effectively accessed to save reading time, consequently, the access bandwidth of the SDRAM is increased, therefore, the performance of the whole system is improved.

The invention provides a distributed network address translation system. The distributed network address translation system comprises an access layer, a multiplex layer and a control layer; middle nodes of the access layer are APs (Access Point); middle nodes of the multiplex layer are MPs (Multiplex Point); middle nodes of the control layer are CPs (Control Point); every AP is an access server; the functions of every AP comprise communicating with an internal network host, selecting public IP (Internet Protocol) resources for the internal network host, communicating with the MP owning the selected public IP resources and performing address translation; every MP is a multiplex server; the respectively owned public IP resources are maintained through every MP and meanwhile every MP is communicated with an external network through the respectively owned public IP resources; every CP comprises an IPS (IP Selector) and a CC (Control Center); every IPS is used for maintaining the public IP address resources of the MPs in the system; every CC is used for performing configuration on every layer of nodes; the APs, the MPs and the CPs are connected with each other through a tunnel which is a transmission layer connecting tunnel. The distributed network address translation system is used for performing the distributed network address translation and accordingly the utilization rate of the IP resources in the NAT (Network Address Translation) system can be improved.

The invention relates to a passive optical interconnection network structure. The passive optical interconnection network structure includes: two-stage optical switching switches; wherein, the two-stage optical switching switches respectively receive read / write request optical signals sent by N processing elements; according to the read / write request optical signals in the Wavelength information is exchanged to realize non-blocking parallel access among 16 processing elements; N is 4*4, 8*8, 16*16, 32*32 or 64*64. The invention relates to an on-chip passive optical interconnection network structure, which is suitable for communication of a large-scale multi-core processing unit structure, and aims to reduce the number of microring resonators and improve Access bandwidth, lower insertion loss, and lower access latency.

The invention discloses a network high available method and device based on a docker and relates to the technical field of a device or method for performing a special program. The method comprises the steps of setting virtual network card devices; adding a docker container network device; and bridging container network cards to the virtual network card devices through network bridge network cards. The method is based on a none network mode of the docker. The bridge network cards are added in a network plug-in mode. In a mode of linking the virtual network cards bonded with ports through the bridge network cards, various containers are supported to enjoy independent networks and independent IPs and do not share ports. Links are redundant, traffic loads are balanced, and the traffic bandwidth is increased. Through application of the method, the purchase cost of establishing a container virtualized system platform is reduced, and moreover, the reusability of server resources on operation of the same kinds of applications is improved.
