Architectural state

The architectural state is the part of the CPU which holds the state of a process, this includes:

• Control registers
  • Instruction Flag Registers (such as EFLAGS in x86)
  • Interrupt Mask Registers
  • Memory management unit Registers
  • Status registers
• General purpose registers (such as AX,BX,CX,DX,etc. in x86)
  • Adder Registers
  • Address Registers
  • Counter Registers
  • Index Registers
  • Stack Registers
  • String Registers

This does not include actual computation units as an ALU for instance.
