Cache block apparatus and methods

A virtual machine apparatus comprising:

• a virtual machine execution engine configured to:
• load an input variable value in conjunction with starting execution of bytecode associated with an application,
• read a cache table entry stored in a cache file related to the application, the cache table entry including (i) a demarcation of a selected portion of the bytecode of the application that is stored within a cache block, (ii) a cache block input variable, and (iii) a cache block output variable,
• compare the loaded input variable value to the cache block input variable, and
• responsive to the loaded input variable value matching the cache block input variable:
• skip execution of the selected portion of the bytecode,
• read the cache block output variable, and
• execute another portion of the bytecode located after the selected portion of the bytecode using the cache block output variable.

A virtual machine apparatus comprising:

• a virtual machine execution engine configured to:
• read a cache table stored in a cache file related to an application specified by bytecode, the cache table including a plurality of cache table entries including (i) a demarcation of a selected portion of the bytecode that is stored within a cache block, the demarcation being the same for each of the cache table entries, (ii) a cache block input variable value, and (iii) a cache block output variable value,
• load an execution value from the bytecode that corresponds to a cache block input variable,
• query each of the cache table entries to determine whether the execution value matches the respective cache block input variable value,
• for the cache table entry with the matching cache block input variable value, determine the cache block output variable value,
• apply the cache block output variable value to at least one of a heap and a stack related to the application, and
• skip execution of the selected portion of the bytecode by executing another portion of the bytecode that is located after the selected portion of the bytecode stored within the cache block.
