Instruction Set 8086 8086 Microprocessor by Ravinder Nath Rajotiya - October 14, 2020April 28, 20210 Platforms for writing 8086 assembly programs. Assembly level language program for the 8086 processors can be written in the following platforms. Directly as hex codes fed into the RAM and executed on a trainer kit DOS debug utility of windows Writing the text file in notepad or gedit and then assembling using the MASM, TASM, NASM assemblers etc. We can also write and run the program in the IDE of C or C++ Classification of instructions 8086 instructions may be classified as: Classification based on size of the instruction: As discussed in topic on instruction format 8086 instruction can be from 1 to 6 byte long. The first two bytes indicate the OPCODE and the addressing Classification based on the addressing modes: The
8085 Classification of Instructions 8085 Microprocessor by Ravinder Nath Rajotiya - September 1, 2020May 10, 20210 This post describes the different classification of the 8085 instructions. Three possible classifications are made based on size, based on addressing mode supported and the functions performed by them. Examples of each type has also been indicated
