Address Registers: Address registers hold addresses and are used by instructions that
indirectly access primary memory. Some processors contain registers that may only
be used to hold an address or only to hold numeric values, others allow
registers to hold either kind of quantity.

General-Purpose
Registers (GPRs): This can store both data and addresses, i.e., they
are combined data/address registers and rarely the register file is unified to include floating point as
well.

Status Registers: These
are registers which hold truth values often used to determine whether some instruction
should or should not be executed.

- Floating-Point Registers (FPRs): These are used to store floating point numbers in many architectures.
- Constant Registers: Constant registers hold read-only values such as zero, one, or pi.
- Vector Registers: These are registers
that
hold data for vector
processing done by SIMD instructions (Single Instruction, Multiple
Data).

Data Registers: These are registers that can hold numeric values
such as integer, floating-point values, as well as characters, small bit arrays and other data.
