Name the architecture and the instruction set for microcontroller?(a) Van- Neumann Architecture with CISC Instruction Set(b) Harvard Architecture with CISC Instruction Set(c) Van- Neumann Architecture with RISC Instruction Set(d) Harvard Architecture with RISC Instruction SetThis question was addressed to me during an internship interview.The question is from Microcontroller (8051) topic in division Prototyping Embedded Devices of IOT

Answer»

Right choice is (b) Harvard Architecture with CISC INSTRUCTION SET

The best I can explain: Harvard architecture has different memory spaces for both program memory and data memory with Complex Instruction Set Computer(CISC). The difference between CISC and RISC is RISC has few INSTRUCTIONS than CISC. Where as in Van- Neumann, program and data memory are same. Van- Neumann is also called as Princeton architecture.
