In a microprogrammed processor, the hardware

doesn't directly execute the instructions in the

ISA

 The hardware executes very simple micro-operations that

are used to implement the instructions

 Each instruction specifies a sequence of micro-operations

that are used to implement the instructions

6 What is the role of a Micro sequencer in Microprogramming Control Unit?

In computer architecture and engineering, a sequencer or microsequencer is a part of the control unit of a CPU. It generates the addresses used to step through themicroprogram of a control store.Usually the addresses are generated by some combination of a counter, a field from a microinstruction, and some subset of the instruction register. A counter is used for the typical case, that the next microinstruction is the one to execute. A field from the microinstruction is used for jumps, or other logic.Since CPUs implement an instruction set, it's very useful to be able to decode the instruction's bits directly into the sequencer, to select a set of microinstructions to perform a CPU's instructions.Most modern CPUs are considerably more complex than this description suggests. They tend to have multiple cooperating micromachines with specialized logic to detect and handle interference between the micromachines.


What is the difference between instruction cycle and machine cycle?

an instruction cycle may consist of a number of machine cycles.


What is the difference between instruction and pseudo-instruction?

A pseudo-instruction : A symbolic representation in a compiler or interpreter. An instruction : a simple statement in any language that defines a task or computation etc.

What is microinstruction execution?

A microinstruction executing system includes a sequencer for controlling sequential readout of microinstructions from a ROM for storage in a microinstruction register and for subsequent decoding by a decoder.


What is a micro-instruction?

microinstruction: An instruction that controls data flow and instruction-execution sequencing in a processor at a more fundamental level than machine instructions. Note: A series of microinstructions is necessary to perform an individual machine instruction.a micro instruction specifies one or more micro oprations for the system.


What is the function of the microinstruction register?

It is a memory register inside the CPU. The function is to hold the current microinstruction. The microinstruction is the bits that drive the control signal and drive the data path.


What is the difference between instruction registers and instruction pointer?

instruction register is used to store the next instruction to be executed. instruction pointer is used to store the address of the next instruction to be executed.

instructions means more than 1 instruction (ex.go home and do your homework) but instruction means 1 instruction (ex.do your homework)

What is the difference between load and store instruction?

Load instruction means to load the instruction from the memory to the processor (accumulator).. But store instruction is opposite of it,it stores information from accumulator to the memory.
