An instruction step is a method of executing a computer program one step at a time to determine how it is functioning. This might be to determine if the correct program flow is being followed in the program during the execution or to see if variables are set to their correct values after a single step has completed.
A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. [1] SOPs aim to achieve efficiency, quality output, and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
The next step is to decode the machine instruction by selecting the proper output line to the hardware module. [148] The final step is to execute the instruction using the hardware module's set of gates. A symbolic representation of an ALU. Instructions to perform arithmetic are passed through an arithmetic logic unit (ALU). [149]
The IBM 704, 709, 704x and 709x store one instruction in each instruction word; IBM numbers the bit from the left as S, 1, ..., 35. Most instructions have one of two formats: Generic S,1-11 12-13 Flag, ignored in some instructions 14-17 unused 18-20 Tag 21-35 Y Index register control, other than TSX S,1-2 Opcode 3-17 Decrement 18-20 Tag 21-35 Y
A quick start guide, or QSG for short, focuses on the most common instructions, often accompanying such instructions with easy-to-understand illustrations. [1] [2] The appearance of a QSG can vary significantly from product to product and from manufacturer to manufacturer. For example, it could be a single A4 sheet, a folded card or a booklet ...
Object model instruction 0xFE 0x01 ceq: Push 1 (of type int32) if value1 equals value2, else push 0. Base instruction 0xFE 0x02 cgt: Push 1 (of type int32) if value1 greater than value2, else push 0. Base instruction 0xFE 0x03 cgt.un: Push 1 (of type int32) if value1 greater than value2, unsigned or unordered, else push 0. Base instruction 0xC3 ...
The contents of registers and memory locations can be examined; if they are correct, the system can be told to go on and execute the next instruction. The Intel 8086 trap flag and type-1 interrupt response make it quite easy to implement a single-step feature in an 8086-based system. If the trap flag is set, the 8086 will automatically do a ...
