Which register is incremented or decremented when loop instruction is executed?

Which register is incremented or decremented when loop instruction is executed?

even register
The even register contains a value which is used to increment or decrement the value in Operand 1. The odd register, which is not coded in the instruction, contains a limit or address against which Operand 1 is compared.

Which of the following is the hexadecimal opcode for SH instruction?

List by Mnemonic Opcode

What is LH in assembly language?

The LH instruction reads a 16-bit integer value from the memory address specified by the argument and puts it in the low 16 bits of the target register specified by the first argument.

What BCT instruction does?

Purpose of Instruction The BCT instruction subtracts 1 from the value of the contents of the target register specified in the first argument. If the value in the target register after the subtraction is zero, no branch occurs. Otherwise the program branches to the specified address.

How many bytes are copied by pop instruction?

The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.

What is emu8086 instruction set?

Data Transfer instruction

What type of instruction is LH in MIPS?

What is Lui in MIPS?

lui is “load upper immediate”, with “upper” meaning the upper 16 bits, and “immediate” meaning that you are giving it a literal value (4097).

What is loop in assembly?

A loop is a block of statements that are repeatedly executed until a condition is satisfied. The assembly language uses JMP instruction to implement loops. However, the processor set can use the LOOP instruction to implement loops conveniently.

What will be done while execution of POP PSW instructions?

In 8085 Instruction set, with the mnemonic POP, we can pop out 2-Bytes from the top of the stack through rp i.e. register pair e.g. BC, DE, HL or AF. Here AF is a register pair formed with Flag and Accumulator registers and also known as PSW (Processor Status Word)….Instruction type POP rp in 8085 Microprocessor.
