Processor registers

In computer architecture, processor register is a collection of small computer memory that is able to work with very high speeds, which is used to execute computer programs. Rirarki processor registers in memory is the highest level, so the speed of the fastest and most expensive price of each bits. Registers are also used as the most rapid in the computer system to perform data manipulation.
The unit of measure is the bit registers, such as 8-bit registers, registers 16-bit, 32 bit registers and so on. Registers included in the category of hardware in the computer.
Register kinds:
• Register data, which is used to store numbers in an integer (integer).
• Register the address, which is used to store memory addresses and also to access the memory.
• general purpose register, which can be used to store numbers and addresses at once.
• floating-point register, which is used to store floating point numbers (floating-point).
• Register a constant (constant registers), which is used to store numbers remain that can only be read (read-only), a sort of phi, null, true, false, and others.
• Register vectors, which are used to store the results of vector processing performed by the SIMD processor.
• special purpose register that can be used to store internal data processor, as well as the instruction pointer, stack pointer, and status registers.
• Register specific to the machine model (machine-specific registers), in some specific architecture, used to store data or settings related to the processor itself. Because the meaning of each register directly incorporated into the design of a particular processor, the register may not be a standard type between processor generations.
