Method and apparatus for identifying hotspot intermediate code in language virtual machine

An apparatus for identifying hotspot intermediate code, wherein the apparatus comprises:

• an obtaining circuit, configured to:
• when a language virtual machine executes a function, obtain an instruction address in an instruction counter;
• a first determining circuit, configured to determine, according to the instruction address that is in the instruction counter and is obtained by the obtaining circuit, whether the instruction address in the instruction counter is greater than or equal to a start address of a native instruction space of the function and less than or equal to an end address of the native instruction space of the function;
• an updating circuit, configured to:
• when the instruction address in the instruction counter is greater than or equal to the start address of the native instruction space of the function and less than or equal to the end address of the native instruction space of the function, increase a current hotness value of the function by a preset value, to update the hotness value of the function;
• and
• a second determining circuit, configured to:
• determine whether an updated hotness value that is of the function and is obtained by the updating circuit is greater than or equal to a hotness threshold of the function, and when the updated hotness value of the function is greater than or equal to the hotness threshold of the function, use intermediate code of the function as hotspot intermediate code.

A non-transitory computer-readable medium storing computer instructions for identifying hotspot intermediate code, that when executed by a baseband processor and an application processor of a terminal, cause the baseband processor and the application processor to perform the method comprising:

• when a language virtual machine executes a function, obtaining an instruction address in an instruction counter, and determining whether the instruction address in the instruction counter is greater than or equal to a start address of a native instruction space of the function and less than or equal to an end address of the native instruction space of the function;
• when the instruction address in the instruction counter is greater than or equal to the start address of the native instruction space of the function and less than or equal to the end address of the native instruction space of the function, increasing a current hotness value of the function by a preset value, to update the hotness value of the function;
• and
• determining whether an updated hotness value of the function is greater than or equal to a hotness threshold of the function, and when the updated hotness value of the function is greater than or equal to the hotness threshold of the function, using intermediate code of the function as hotspot intermediate code.
