The Producer-Consumer problem is a classic synchronization problem in operating systems where producers generate data and place it into a buffer, while consumers remove data from the buffer. This visualization demonstrates how semaphores and mutual exclusion can be used to coordinate access to the shared buffer.
Standard producer-consumer with mutex
Create a fixed-size buffer and initialize semaphores for mutual exclusion and resource counting.
Producers wait for an empty slot, acquire mutex, add item to buffer, release mutex, and signal that a slot is full.
Consumers wait for a full slot, acquire mutex, remove item from buffer, release mutex, and signal that a slot is empty.
Semaphores ensure that producers don't overwrite data and consumers don't read empty slots, preventing race conditions.
