Embodiment

[0071] The present invention provides a kind of method that inserts cycle command in 1553 bus sequence tables, comprises the following steps, as figure 1 Shown:

[0072] Step 1, define an array N, wherein, N={N1, N2,...,Ni,...,Nn}, Ni represents a command, defined as Ni={Hi, Si, Li, Ti}, H represents the order number, S represents the command type, L represents the data length, T represents the period (ms);

[0073] Step 2, calculate the number of small periods and the value of small periods;

[0074] Take out and compare the T value of each command, select the maximum cycle value Tmax and the minimum cycle value Tmin, and the number of small cycles is 2 q , q satisfies 2 q The smallest integer greater than or equal to Tmax / Tmin, the period value of each small period is equal to the minimum period value Tmin;

[0075] Step 3, put Ni with the same period Ti into the array Mi, and sort Mi according to Di; M={M1,M2,...,Mm}, a command group with the same period in M ​​Mi={Di1,...

Abstract

The present invention relates to a method for inserting a cycle command into a 1553 bus sequence table. The method for carrying out insertion by screening and inducing attribute information, which is disclosed by the present invention, solves the technical problems of large difference between the numbers of commands in each minor cycle in a command table, and unbalance load and efficiency of each minor cycle, and realizes communication stability of a 1553 bus transmission system.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a method for inserting a periodic command into a 1553 bus sequence table. Background technique [0002] When the 1553 bus system communicates, the bus configuration table needs to be loaded on the bus controller side, and the core component of the bus configuration table is the bus command execution sequence. The sequence table is mainly used to control the bus transmission, so that the bus data is transmitted according to the predetermined transmission direction, period, data transmission length and target. The sequence table is arranged by the command first address pointer, and the corresponding command can be found in the command table through the command first address pointer, so the sorting of the sequence table can be converted into the sorting of the command transmission sequence. [0003] The sequence table stipulates that its length cannot exce...
