an instruction cycle may consist of a number of machine cycles.
No. Generally, one instruction in a high level language corresponds to many instructions in machine language.
Assembly language to machine code translation is a "one to one" translation process, as every individual instruction expressed in the assembly language corresponds to exactly one machine instruction. Note this does not hold for pseudo instructions or expanding macros, which are supported by some assemblers.
beside its very convenient and easy to follow with, almost all high, low, and machine languages instruction are formulated to comply with the structure theorem.

A pseudo-op is an assembly language instruction that specifies an operation of the assembler i.e about the base register & its contents e.g. USING instruction. On the other hand, a machine-op instruction. That represents a machine instruction to the assembler e.g. BR instruction is a machine-op instruction

To add a new machine language instruction to an processor instruction set, you need to replace the microcode of the processor.
No. Generally, one instruction in a high level language corresponds to many instructions in machine language.
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.
The instruction phase together with the execution phase is called a "Machine Cycle".
It is an assembler language programmer

Many companies see the instruction book as a vital part of a sewing machine, and thus sell instruction books through various distributors. One such site is www.shoppersrule.com, under the "sewing mall category." You can find instruction manuals for more than 15 sewing machine brands.

• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
