![]() Rp is incremented (As element has been added to buffer) Rp is a register which keeps the value of m ![]() count is further divided into 3 lines code represented in the block in both the producer and consumer code.count keeps the count number of elements in the buffer." out" used in consumer code represent first filled buffer." in" used in a producer code represent the next empty buffer.Let's see the code for the above problem: Producer Code Producer Code Let's understand above Producer and Consumer code:īefore Starting an explanation of code, first, understand the few terms used in the above code: Accessing memory buffer should not be allowed to producer and consumer at the same time.In case it is found that the buffer is empty, the consumer is not allowed to use any data from the memory buffer. Data can only be consumed by the consumer if and only if the memory buffer is not empty.In case it is found that the buffer is full, the producer is not allowed to store any data into the memory buffer. The producer should produce data only when the buffer is not full.Let's understand what is the problem?īelow are a few points that considered as the problems occur in Producer-Consumer: Whereas the task of the Consumer is to consume the item from the memory buffer. The task of the Producer is to produce the item, put it into the memory buffer, and again start producing items. The same memory buffer is shared by both producers and consumers which is of fixed-size. There is one Producer in the producer-consumer problem, Producer is producing some items, whereas there is one Consumer that is consuming the items produced by the Producer. The Producer-Consumer problem is a classical multi-process synchronization problem, that is we are trying to achieve synchronization between more than one process.
