ACentral Processing Unit (CPU)is the brains of a computer system - it's essentially what tells the computer what to do and how to do it. A CPU is composed of circuitry, which consists of three main components: a control unit, an arithmetic/logic unit (ALU), and a register set. The...
The CPU is the heart of any system. It is usually made of two main components the arithmetic logic unit, or ALU, and the control unit, or CU. TheALUinvolves in performing the logical and arithmetic operations of the CPU. It consists of an arithmetic logic unit and a set of registers w...
CPUs work on a cycle that is managed by the control unit and synchronized by the CPU clock. This cycle is called theCPU instruction cycle, and it consists of a series of fetch/decode/execute components. The instruction, which may contain static data or pointers to variable data, is fetched...

Figure 23 Activity Operations shows the activity of three threads. Thread-1 sends the activity start event and then waits for Thread-2 and Thread-3 to complete their tasks. Thread-2 completes its task first, followed by Thread-3. When both threads have completed their tasks, Thread-1 is ...

In order to add shadows to my scene I've implemented a technique calledShadow Mapping. It consists of three parts: Render the depth of the scene from the Light point of view. We store in each pixel the distance from the light to the closest object that it sees. This is called a Shado...
linear address space for the program and the os/executive consists of an array of segments of up to 64 KBytes in size each. maximum size of the linear address space in real-address mode is 220 bytes. Paging and Virtual Memory when paging is disabled, each linear address has a one-to-on...
Arithmetic-Logic Unit (ALU): This unit consists of electronic circuits that execute arithmetic and logical operations. Usually, the ALU executes four arithmetic operations – addition, subtraction, multiplication, and division. Furthermore, it typically executes three logical operations – equal-to, less...
