What is ARPL in microprocessor?

ARPL appears in operating system software, not in application programs. It is used to guarantee that a selector parameter to a subroutine does not request more privilege than the caller is allowed. The second operand of ARPL is normally a register that contains the CS selector value of the caller.

What are system instructions in 80386?

The instructions SMSW and LMSW are provided for compatibility with the 80286 processor. 80386 programs access the MSW in CR0 via variants of the MOV instruction. HLT stops the processor until receipt of an INTR or RESET signal.

What does Arpl mean?

The latest Artisan Recognition of Prior Learning (ARPL) process as prescribed by the Department of Higher Education and Training (DHET) is designed to assist candidates who wish to pursue careers in artisanal trades such as diesel mechanics, welding, fitting and boiler-making.

What are the features of 80386?

What is the purpose of the bs16 pin on the 80386 microprocessor?

#: The bus size – 16 input pin allows the interfacing of 16 bit devices with the 32 bit wide 80386 data bus. Successive 16 bit bus cycles may be executed to read a 32 bit data from a peripheral.

How does RPL work in Australia?

Recognition of Prior Learning (RPL) is an assessment process used by RTOs to evaluate a person’s skills, knowledge and experience gained through working and learning, in Australia or overseas, be it through life experience, work or other activities such as volunteering.

What are the features of microprocessor?

Features of Microprocessor Low Cost – Due to integrated circuit technology microprocessors are available at very low cost. It will reduce the cost of a computer system. High Speed – Due to the technology involved in it, the microprocessor can work at very high speed. It can execute millions of instructions per second.

What are the three working modes of 80386?

The 80386 has three processing modes: Protected Mode. Real-Address Mode. Virtual 8086 Mode.
