This document discusses microcontroller architectures and specifications. It covers CISC vs RISC instruction sets, Harvard and Von Neumann memory architectures, and the differences between them. The Harvard architecture has separate buses for program and data memory allowing simultaneous processing, while the Von Neumann architecture has a single bus requiring sequential processing. The AVR microcontroller uses a Harvard architecture allowing faster execution and easier memory calculation for applications.

2. 0.3 Arsitektur mikrokontroler dan
spesifikasinya

3. Arsitektur Mikrokontroler /
Prosesor
• Based on the instruction set are CISC
(Complex Instruction Set Computer) and
RISC (Reduced Instruction Set Computer)
• Based on the memory architecture are
Harvard architecture and Von Neumann
architecture

4. CISC vs RISC
• CISC are hardware optimized, complex
instruction, greater machine cycle per
instruction e.g. 12 clocks, hardware circuitry
more complex, draws greater power
consumption
• RISC are software optimized (compiler),
simpler instruction, lower machine cycle per
instruction e.g. 1 clocks, simpler hardware
circuitry, draws lower power consumption

5. Arsitektur Von-Neumann
• Hanya mempunyai
satu blok memori dan
8-bit bus data
• Akibatnya program
dan data diproses
secara bergantian,
tidak bisa langsung
bersamaan

6. Arsitektur Harvard
• Memiliki dua bus data
yang berbeda
• Program dan data
dapat diproses
bersamaan
• Memudahkan pada
saat menghitung
keperluan memori
bagi suatu aplikasi

7. Harvard vs. Von Neumann
• Harvard micro
architecture : separate
between program and
data, faster execution,
e.g. Intel MCS-8051,
Atmel AVR, Microchip
PIC, Texas Instrument
DSP, ARM (Advanced
RISC Machine)
• Von Neumann : merge
between program
instruction and data,
simpler hardware
interface, e.g. Intel
IAPx-86 (80x86 up to
Pentium 4, Core)
