Register processors, computer architecture, is a small amount of computer memory that works with very high speed that is used to perform the execution of computer programs by providing rapid access to the values of the public to use. Generally, the values that are commonly used values that are executed in a certain time.

Register processors stood at its highest level in the hierarchy of memory: this means that the speed is the fastest, most capacity is small and the price of each is the most high bitnya. Register is also used as the most rapid in the computer system to perform data manipulation. Register generally measured with a bit that can ditampung by it, such as "8-bit register", "16-bit register", "32-bit register", or "register a 64-bit" and others.

The term can register at this time referring to the set of registers that can be indexed directly to do the input / output of an instruction is defined by a set of instructions. for this term, digunakanlah the words "Register Architecture." For example Intel x86 instruction set defines a set of eight to register with the fruit size of 32-bit, but the CPU is the x86 instruction set may contain more than eight 32-bit register.

Register divided into several classes:

* Register data, which is used to store the numbers in the 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 of all at once.
* Register floating-point, which is used to store the numbers float point numbers (floating-point).
* Register constant (constant registers), which is used to store the numbers remain that can only be read (a read-only), such as phi, null, true, false and other.
* Register vectors, which is used to store the results of vector processing done by the SIMD processor.
* Special purpose register that can be used to save internal data processors, as well as the instruction pointer, stack pointer, and the status register.
* Register for a specific model of machine (machine-specific registers), in particular some of the architecture, used to store data or settings associated with the processor itself. Because the meaning of each register directly inserted in a specific processor design course, this type of register may not be a standard between processor generations.

The following table lists the size of a register and prosesornya
