The 8051 assembly language programming is based on the memory registers. The 8051 microcontroller consists of RAM and ROM memories to store instructions.Ī Register is the main part in the processors and microcontrollers which is contained in the memory that provides a faster way of collecting and storing the data. The microcontroller requires a program to perform the operations that require a memory for saving and to read the functions. ![]() The 8051 microcontroller is the CISC based Harvard architecture, and it has peripherals like 32 I/O, timers/counters, serial communication and memories. M icrocontrollers or processors can understand only binary language in the form of ‘0s or 1s’ An assembler converts the assembly language to binary language, and then stores it in the microcontroller memory to perform the specific task. 8051 Programming in Assembly LanguageĪssembly programming language is developed by various compilers and the “ keiluvison” is best suitable for microcontroller programming development. The assembly language is developed by mnemonics therefore, users cannot understand it easily to modify the program. The embedded designers must have sufficient knowledge on hardware of particular processor or controllers before writing the program. ![]() The assembly language is a fully hardware related programming language. 8051 Programming 8051 Programming in Assembly Language
