- 10. THE ARCHITECTURE OF PENTIUM MICROPROCESSOR
- 11. REGISTER SET • is to hold temporary results and control the execution of the program • EAX, ECX, EDX, EBX, ESP, EBP, ESI, or EDI • The 32-bit registers are named with prefix E, EAX, etc, and the least 16 bits 0-15 of these registers can be accessed with names such as AX, SI. • Similarly the lower eight bits (0-7) can be accessed with names such as AL & BL.
- 12. REGISTER SET • The comparison of the available flags in 16- bit and 32-bit microprocessor is may provide some clues related to capabilities of these processors. • All of these flag registers include 6 flags related to data conditions (sign, zero, carry, auxiliary, carry , overflow, and parity) and three flags related to machine operations, interrupts, Single-step and Strings)
- 13. REGISTER SET • The instruction pointer EAP known as program counter (PC) in 8-bit microprocessor, is a 32-bit register to handle 32-bit memory addresses, and the lower 16 bit segment IP is used for 16-bit memory address. • The flag register is a 32-bit register, however 14-bits are being used at present for 13 different tasks;
- 14. REGISTER SET • The I/O Privilege uses two bits in protected mode to determine which I/O instructions can be used, and the nested task is used to show a link between two tasks. • The processor also includes control registers and system address registers, debug and test registers for system and debugging operations.
- 15. PENTIUM PROCESSOR MODES Protected mode • the native state of the microprocessor • the recommended mode that all new applications and operating systems should target • all instructions and architectural features are available • capabilities of protected mode is the ability to directly execute "real-address mode"
- 16. PENTIUM PROCESSOR MODES Real-Address Mode or Real- Mode • programming environment of the processor, with a few extensions • reset initialization places the processor in real mode where, with a single instruction, it can switch to protected mode
- 17. PENTIUM PROCESSOR MODES System Management Mode • a standard architectural feature unique to all new Intel microprocessors • provides an operating-system and application independent • transparent mechanism to implement system power management • OEM differentiation features
