Problems solved by technology

If the external environment changes and the filter coefficient needs to be replaced, the system can only return to the initial state. At this time, the data volume of the coefficient is large, and the transmission time is very long. The system cannot quickly replace the filter coefficient, that is, the timeliness of the system and poor flexibility

Embodiment Construction

[0010] The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing.

[0011] In the present invention, considering the full utilization of the storage space, when the storage space is divided into two parts, the utilization rate of the storage space reaches the maximum, so the storage space is divided into two parts as an example for illustration.

[0012] As shown in Figure 1, the storage space is divided into two equal parts, that is, n=1.

[0013] In the case of conjugation, the filter coefficients processed by the ASIC chip have a total of 512 channels, which are stored in 16 built-in SRAMs respectively. According to a group of 2 blocks, a total of 8 groups, a total of 128K storage units, each storage unit has a word length of 32 bit. Based on the ASIC design idea, the 8 groups of coefficient storage spaces are divided into two parts, ie n=1.

[0014] As shown in Figure 2, the system starts to run. Firstly, the regis...

Abstract

The invention relates to a dynamic loading realization method in the radar signal processing, a core idea is that the storage space of the filter coefficient is divided into 2<n> parts (n is equal to 1, 2, 3). When the first part operation is proceeded, at the same time the reading and writing of the next part coefficient is also proceeded, and when the first part operation is done, the second part coefficient is fully wrote, the second part operation is continued to proceed, and at the same time of the second part operation, new coefficient is continued to write to cover the accomplished operation coefficient space, which is alternately proceeded in sequence. The invention is mainly applicable to the filter processing of the radar signal processing, the filter coefficient can be timely adjusted according to the change of the external environment, the bad real-time performance of the radar signal processing system is solved when the external environment is changed.

Description

technical field [0001] The invention relates to a dynamic loading ASIC realization method, in particular to a dynamic loading ASIC realization method in radar signal processing. Background technique [0002] In radar signal processing, the coefficients of the filter are generally read into the storage unit in advance, and the real-time collected data are calculated with the filter coefficients during the filtering operation to achieve the purpose of filtering. The larger the number of digits, orientation, and order of processed data, the larger the storage capacity required. If the external environment changes and the filter coefficient needs to be replaced, the system can only return to the initial state. At this time, the data volume of the coefficient is large, and the transmission time is very long. The system cannot quickly replace the filter coefficient, that is, the timeliness of the system and poor flexibility. Contents of the invention [0003] The problem to be...
