Multi-Thread Processors and Methods for Instruction Execution and Synchronization Therein and Computer Program Products Thereof

A machine-readable storage medium comprising a computer program, which, when executed, causes an apparatus to perform a method for instruction execution and synchronization in a multi-thread processor, wherein multiple threads are running in the multi-thread processor and each of the threads can simultaneously execute a same instruction sequence, the method comprising:

• receiving a source code or an object code;
• compiling the source code or the object code to generate the instruction sequence, wherein instructions for all of function calls within the instruction sequence are sorted according to a calling order;
• providing each thread a counter value, each counter value pointing to one of the instructions in the instruction sequence;
• and
• determining a main counter value according to the counter values of the threads such that all of the threads simultaneously execute the instruction of the instruction sequence that the main counter value points to.
