Memory cells store at the beginning of 2000 h 10 bytes with symbols, statistical program in a negative number, deposit and the statistical results to 3000 h unit,

CodePudding user response:

You need to what platform based on single chip microcomputer? Different platforms microcontroller is different, there is 2000 h and 3000 h is RAM or the address of FlashROM area? Problem description is not clear,

CodePudding user response:

This is done is microcomputer principle of no other description of the book

CodePudding user response:

Ha ha microcomputer principle, that is, 8086, 16 bits CPU; Looking for a 8086 c compiler, with c implementation first, and then the disassembly

CodePudding user response:

C programming in the compiler with the disassembly of the tool, the disassembly is the assembly code
