    The hardware semaphore module requires that all cores competing for a semaphore gate must present a translated core ID as a valid parameter to lock a gate. This routine reads the core Process ID (PID) and converts it to an equivalent ID the hardware semaphore module will accept.

    In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple processes in a concurrent system such as a multitasking operating system. A semaphore is simply a variable. This variable is used to solve critical section problems and to achieve process synchronization in the multi processing environment.

Misconception: There is an ambiguity between binary semaphore and mutex. We might have come across that a mutex is binary semaphore. But they are not! The purpose of mutex and semaphore are different.
