Data Processing Method and Related Apparatus

A method comprising:

• generating a first function based on target constant data to be accessed in a first code, wherein a length of the target constant data is greater than a preset threshold, and wherein the first function comprises the target constant data;
• inserting, based on a location of a second function in the first code, a call instruction and an access instruction into the first code to obtain second code, wherein the second function needs to access the target constant data, wherein the call instruction instructs to call the first function, wherein the first function returns an address of the target constant data in response to the call instruction, and wherein the access instruction instructs to access the target constant data based on the address;
• label the second code as being stored into a first storage area not having a read permission;
• and
• label the first function as being stored into a second storage area having the read permission.

An electronic device, comprising:

• a memory configured to store instructions;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the electronic device to:
• obtain target constant data to be accessed in a first code, wherein a length of the target constant data is greater than a preset threshold;
• insert, based on a first location of an objective function in the first code, a plurality of data transfer instructions into the first code to obtain a second code, wherein the objective function needs to access the target constant data, wherein each of the data transfer instructions comprises a first part of data in the target constant data, and wherein the data transfer instructions write the target constant data into a register;
• and
• label the second code as being stored into a storage area not having a read permission.
