Let us consider the pining details of the 68HC11 as shown below.
Each pin has a defined function, some easy, some complex. A microprocessor designer should understand all the pins and timing waveforms. Let us examine some of the important pins. The address pins A0 ->A15 provide the outside world with details of the address the p wants to read or write to. The data pins D7-> D0 provide the outside world with the pathway to receiving or sending data to and from the mp. The third group of pins are called the ' asynchronous' bus control. This provides details of valid address' (Address strobe AS), read/write (R/W) and system clock (E). Some other pins exist for interrupts and other IO devices. We shall consider a simple hardware design using ideal components, but first we shall discuss the read/write cycles of the 68HC11.
Explain the Exit (status) Function Exit function causes the calling process to be terminated. Actually, all file descriptors are immediately closed but the process is not
Write a note on the usage of semaphores. Semaphore is a synchronization tool and it is a variable having integer values. It is accessed only by two standard atomic operations w
Synchronization serves two purposes: 1) to ensure safety for updates on shared data (e.g. to avoid races conditions), and 2) to coordinate and order actions taken by threads (e.g.
