and receiving the initialization instruction through the initialization control circuit, and controlling the table entry read-write control circuit in the corresponding component to initiate initialization write operation to a random access memory.

4. The method of claim 2, further comprising;

transmitting the updated parameter values to the table initialization state register through the table initialization state register corresponding to each chip table entry;

performing logic or operation on the parameter value of each table entry initialization state register to obtain an initialization state identifier;

and updating the parameter value of the initialization state register to the initialization state identifier.

5. The method of claim 1, wherein the confirming whether the chip completes initialization according to the parameter value of the initialization status register comprises:

when the parameter value is an initialization completion identifier, determining that the chip completes initialization;

and when the parameter value is a non-initialization completion identifier, determining that the chip does not complete initialization.

6. The method of claim 1, wherein the initializing, by the initialization control component, configuration of the corresponding chip table entry in the chip comprises:

determining a chip table entry to be initialized from a plurality of chip table entries as a target chip table entry;

writing a non-initialization completion identifier into a table entry initialization state register corresponding to the target chip table entry;

and performing initialization configuration on the target chip table entry through an initialization control component corresponding to the target chip table entry.

7. The method of claim 6, further comprising:

inquiring the parameter value of an initialization register in an initialization control component of the target chip table entry;

and judging whether the target chip table entry completes initialization according to the current parameter value of the initialization state register.

8. A chip starting initialization device is provided with a table entry initialization state register and an initialization control assembly corresponding to each chip table entry; characterized in that the device comprises:

the initialization configuration module is used for performing initialization configuration on a corresponding chip table entry in the chip through the initialization control component when the chip is detected to be started;

the register parameter value query module is used for querying the parameter value of the initialization state register;

and the chip initialization confirming module is used for confirming whether the chip completes initialization according to the parameter value of the initialization state register.

9. A computer device comprising a memory and a processor, the memory storing a computer program, wherein the processor implements the steps of the method of any one of claims 1 to 7 when executing the computer program.

10. A chip applied in the method of any one of claims 1 to 7, wherein the chip comprises one or more chip table entries, an initialization status register, and an initialization control component corresponding to each chip table entry; the initialization control component comprises a table entry read-write control circuit, a table entry initialization control circuit and a table entry initialization state register.
