Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [10] making it possible to store on non-binary media such as paper tape, punch cards, etc., to display on text terminals or be printed on line-oriented printers. [11]
Computer engineers often need to write out binary quantities, but in practice writing out a binary number such as 1001001101010001 is tedious and prone to errors. Therefore, binary quantities are written in a base-8, or "octal", or, much more commonly, a base-16, "hexadecimal" (hex), number format. In the decimal system, there are 10 digits, 0 ...
SIC uses a special assembly language with its own operation codes that hold the hex values needed to assemble and execute programs. A sample program is provided below to get an idea of what a SIC program might look like. In the code below, there are three columns. The first column represents a forwarded symbol that will store its location in ...
BEYE, also known as Binary EYE, BIEW, Binary View is a multiplatform portable viewer of binary files with a built-in editor that functions in binary, hexadecimal, and disassembler modes. It uses native Intel syntax for disassembly.
Below is the full 8086/8088 instruction set of Intel (81 instructions total). [2] These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts.
In a typical application, a compiler or assembler converts a program's source code (such as C or assembly language) to machine code and outputs it into a HEX file. The HEX file is then imported by a programmer to write the machine code into non-volatile memory, or is transferred to the target system for loading and execution.
This scheme can also be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421, and is the most common encoding. [12] Others include the so-called "4221" and "7421" encoding – named after the weighting used for the bits – and "Excess-3". [13]
When written in assembly language, the instruction is written like this: INT X. where X is the software interrupt that should be generated (0-255). As is customary with machine binary arithmetic, interrupt numbers are often written in hexadecimal form, which can be indicated with a prefix 0x or with the suffix h.
