What is the mezzanine bus?
In computers, the central processing unit (CPU) acts as a brain and sends messages to different parts of the computer and other components. These signals are transmitted by a system of electrical sockets called a bus. The CPU is now so fast that they need more than one bus to carry information. The specialized bus that directs and from the CPU to a high -speed peripheral, such as memory cards, is called an intermediate bus or mezzanine card. The name mezzanin comes from the word mezzano , which means medium. The bus is a bridge that connects other cards on a CPU computer and allows easy quick communication. Without a bus, the CPU would have to be firmly connected to each card and component separately.
Early computer designs used CPUs and bus, which both took place at the same speed. As computers grew more sophisticated and faster, a new TEPPO bus system with faster processors was needed. Most computers now have more than oneA bus that can handle all the information sent to and from the CPU. Today, most manufacturers monitor common settings for buses, called specification of the peripheral components (PCI). PCI was created in the 90's. The common type of mezzanine Card (PCM) is a common type of mezzanine bus.
different PCMs are available for specific needs. Different models work with analog or digital communication or both. PCMS occupies only one slot in the motherboard. Since the slots are left to connect other cards, it allows the user to gain greater flexibility of the computer. PCMS also allows computers to use newer and faster peripherals without changing the motherboard.
Components and software are sending messages to CPU constantly through various buses, such as mezzaninautobus. To process all CPU operations, buses send requirements via buffer memorythose. The buffer is a memory area used for temporary storage.
The buffer helps the computer storage and then run the requirements. The buffer holds all transactions sent to and from the CPU. These applications are then completed in the receipt or according to any priority processing rules determined by the user.
The buffer is created using the memory of the random access of the computer (RAM). Information can be collected faster from RAM than from a hard disk memory. Usually only a certain amount of RAM is assigned to the buffer. In general, the larger the buffer, the less RAM, which is available for other tasks.
