in computer central processing units, micro-operations (also known as a micro-ops or μops) are detailed low-level instructions used in some designs to implement complex machine instructionsA micro-operation is an elementary CPU operation, performed during one clock pulse.An instruction consists of a sequence of micro-operations.
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.
Push instruction pushes two byte of data on the top of the stack.
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
micro controller is software and fpga is hardware

Micro operation is the level 2 operation, it is excute directly from hardware. Mainly used in provide macro instruction. Macro operation is the level more than 2 (3,4) operation, depend on your CPU structure. Sometime, we call its assembly operation. It is excute by micro operation.

Micro-Processor programming model refers to the Micro-Processor system as seen by a programmer. It involves the following: The Instruction Set - The Micro-Processor internal Registers - The way Micro-Processor accesses the memory (Addressing - Mode): Micro-Processor 'Fetches' (reads) an instruction from memory, 'Decodes' (interprets) the instruction, and then 'Executes' (carries out the task) the instruction. It repeats the cycle for next instruction. By Fijabi Isaac M. Tech Computer Sc.
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
macro
To get the next micro instruction to be executed.
