[0023] FIG. 1 is a flowchart of a clock management method provided by an embodiment of the present invention. As shown in Figure 1:
[0024] Step 101: Construct each clock in the system as a node, construct the superior of each clock as the parent node of the clock, and construct the subordinate of each clock as the child node of the clock.
[0025] Step 102: Construct a clock tree according to the constructed nodes.
[0026] This step may be implemented in the following manner: Firstly, an adding instruction from the user is received. Then judge whether the parent node of the currently added node is a root node according to the received adding instruction, if yes, then add the currently added node as a source node to the clock tree, otherwise, use the currently added node as a source node The child nodes of its parent node are added to the clock tree.
[0027] Through the above method, a clock tree can be constructed.
[0028] Step 103: Manage clocks in the system accordi...

[0040] FIG. 2 is a flowchart of a clock management method provided by an embodiment of the present invention. as shown in picture 2:
[0041] Step 201: Construct each clock in the system as a node, construct the superior of each clock as the parent node of the clock, and construct the subordinate of each clock as the child node of the clock.
[0042] In this step, when constructing a node for each clock, the content of the node may include: the address of the clock, the addresses of the upper and lower levels of the clock, the clock value modification method and clock value restriction conditions preset for the node , the way of reading the clock value and the way of updating the clock, and the flag of the clock, the flag is that the modification is successful or the modification is not successful.
[0043] Wherein, the restriction condition of the clock value may be an interval restriction, such as restricting the clock value of the clock to 30Mhz-50MHz; it may also be a poi...

[0068] As shown in FIG. 4 , the clock management device provided by the embodiment of the present invention includes: a node storage module 401 , a construction module 402 , a tree storage module 403 and a management module 404 .
[0069] The node storage module 401 is used to configure each clock in the system as a node storage, and configure each clock's upper level as the clock's parent node storage, and each clock's lower level as the clock's child node storage.
[0070] The construction module 402 is configured to receive an addition instruction from a user, select a corresponding node from the node storage module 401 to construct a clock tree according to the received addition instruction, and store the constructed clock tree into the tree storage module 403 .
[0071] The tree storage module 403 is used for storing the clock tree.
[0072] The management module 404 is configured to manage clocks in the system according to the clock tree in the tree storage module 403 . ...
