What is Threaded system.
Threaded system: At times we require implementing an operating system which can process multiple threads. Many threads are handled through the kernel using a real-time clock interrupt. One way for scheduling processes in a small RTOS is to utilize a time slice to switch among various processes. The fundamental time slice can be any period and is somewhat dependent upon the execution speed of the microprocessor. All time slices is activated through a timer interrupt. The interrupt service procedure should look to a queue to see whether a task is obtainable to execute, and when it is, this must start execution of the new task. When no new task is present, this must continue executing an old task or enter an idle state and also wait for a new task to be queued. This queue is circular and may have any number of tasks for the system up to a few finite limits.
Open the GetSParameter schematic. You will need to modify the design to include the biasing components. (Even at this stage I would recommend the use of models of real resistors th
Q. Explain Amplitude-shift keying? A carrier's amplitude is keyed between two levels (binary 1 and 0) in binary ASK. Figure shows the functions of a coherent ASK communication
How the interrupts can be masked/unmasked in 8086? The 8086 interrupt priorities are concerned; software interrupts have the highest priority, followed by NMI followed by INTR.
Define pipelining? In 8086, to speedup the implementation of program, the instructions fetching and implementation of instructions are overlapped each other. This method is kno
