  • What are ARM condition codes?

    CS or HSCarry set or Unsigned higher or sameGreater than or equal, or unorderedCC or LOCarry clear or Unsigned lowerLess thanMINegativeLess thanPLPositive or zeroGreater than or equal, or unordered

  • What is the size of ARM opcode?

    ARM's instruction set is variable-length, which means that different instructions can have different sizes, ranging from 16 to 64 bits.
    This allows ARM to pack more instructions into a smaller memory space, reducing the code size and the number of memory accesses.

  • What are the ARM instruction formats?

    Assembly language is a low-level programming language for a computer or other programmable device that is closest to the machine language.
    It is often specific to a particular computer architecture so there are multiple types of assembly languages.
    ARM is an increasingly popular assembly language.
