Register organization<\/strong> is the arrangement of the registers in the processor. The processor designers decide the organization of the registers in a processor. Different processors may have different register organization. Depending on the roles played by the registers they can be categorized into two types<\/strong>, user-visible register and control and status register.<\/p>\n

Before learning register organization in brief, let us discuss what is register?<\/p>\n

What is Register?<\/h2>\n

Registers<\/strong> are the smaller<\/em> and the fastest<\/em> accessible memory units<\/strong> in the central processing unit (CPU). According to memory hierarchy, the registers in the processor, function a level above<\/strong> the main memory<\/strong> and cache memory<\/strong>. The registers used by the central unit are also called as processor registers<\/strong>.<\/p>\n

A register can hold the instruction, address location, or operands<\/em>. Sometimes, the instruction has register as a part of itself.<\/p>\n

Types of Registers<\/h2>\n

As we have discussed above, registers can be organized into two main categories i.e. the User-Visible Registers<\/strong> and the Control and Status Registers<\/strong>. Although we can\u2019t separate the registers in the processors clearly among these two categories.<\/p>\n

\"Register<\/p>\n

This is because in some processors, a register may be user-visible and in some, the same may not be user-visible. But for our rest of discussion regarding register organization, we will consider these two categories of register.<\/p>\n
