[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0066] In the present invention, for each memory space in the memory of the interface board, corresponding storage state identifiers are set respectively, and the state of each memory space is known by detecting each storage state identifier on the CPU side, thereby detecting the current processing capability of the CPU, thereby obtaining the The forwarding capability of the CPU.
[0067] Usually, the CPU adopts the BD mechanism to manage the memory space. Therefore, the technical solution of the present invention will be described in detail below by taking the storage status flag as BD as an example.
[0068] Fig. 3 is an exemplary flow chart of a method for realizing dynamic detection of forwarding capability in the present invention. The method can ...
