This helps you determine which instruction is being executed and what The code for the assembler and simulator is in the src/ directory. While this was fine for a small emulator, I knew this wouldn't work for something larger. What would be the proper way of implementing the clock speed of the CPU? I've tried searching but found nothing, and most intel 8080 emulators are written in C++. The default is Tiny Basic. The Intel 8080 is an 8-bit processor with 7 eight-bit registers, a stack pointer, and a program counter. CALL instructions branch to the absolute address Duration of conditional calls and returns is different when action is taken or not. Editor The Editor is a stripped down version of a multiline editor application such as the Windows Notepad or the macOS TextEdit.
