8051 mcu, von Neumann vs Harvard Architectures

We can classify computer architectures into two categories:
von Neumann architecture: computers has a single, common memory space in which both program instructions and data are stored. There is a single internal data bus that fetches both instructions and data. They can not be performed at
the same time
Harvard architecture: computers have separate memory areas for program instructions and data. There are two or more internal data buses, which allow simultaneous access to both instructions and data. The CPU fetches program instructions on the program memory bus.

Learning Machine Code with 8-bit Microcontrollers

To understand deeply in processor architecture, we have to learn the Machine Code. I decide to select the 8051 microcontroller as a microprocessor model. A microcontroller (or MCU) is a computer-on-a-chip. They integrate many modules on one chip such as RAM, Flash memory, EEPROM, serial ports (UARTs), I²C, Serial Peripheral Interface (SPI), analog-to-digital converters (ADC), clock generator (XTAL) and more.
