Belly is in Pаris. Cоnrаd аnd Jeremiah bоth want tо communicate with her. You are tasked to implement a messaging system, named TSITP, to help them communicate. TSITP uses three processes, PB, PC, PJ to represent Belly, Conrad, and Jeremiah, and they share the same mailbox. PC and PJ both write messages to the mailbox; PB only reads messages because Belly is not interested in writing back. The mailbox can store at most 20 messages, so PC and PJ have to wait when the mailbox is full. The processes use semaphores to synchronize. A. [10pts] Follow the template below to develop the pseudocode for initializing the shared data and the entry section and exit section of PJ and PB. No need to write any code for the critical section. No need to write the code for PC. B. [10pts] Belly now wants to prioritize Conrad’s messages over Jeremiah’s. So PJ has to wait when there are 10 messages from Jeremiah in the mailbox; PJ can put a new message in the mailbox only if the number of messages from Jeremiah in the mailbox is less than 10 AND the mailbox is not full. Based on the solution you developed above and following the same template, develop the pseudocode for initializing the shared data and the entry section and exit section of PJ and PB. No need to write any code for the critical section. // Define your shared data structures here PJ PB while(TRUE) { // your entry section here // Write a message and store it in the mailbox // your exit section here } while(TRUE) { // your entry section here // Retrieve a message from mailbox and read it // your exit section here }
