Hypothetical Architecture Overview

Processor: Simplified RISC$-$like architecture, focusing on ease of understanding and efficient execution of basic operations.

Memory: Unified memory model with separate sections for program code and data storage, facilitating direct and easy access.

Registers: A set of general$-$purpose registers, including special registers for instruction pointer $($IP$),$ accumulator $($ACC$),$ and flags for condition checks.

Instruction Set: A minimal set covering basic arithmetic operations $($ADD$,$ SUB$),$ logic operations $($AND$,$ OR$,$ NOT$),$ and I$/$O operations $($IN$,$ OUT$).$

Instruction and Data Formats

Instruction Format: Fixed$-$length, $3$ parts $-$ opcode $(8$ bits$),$ source register$/$address $(8$ bits$),$ destination register$/$address $(8$ bits$).$

Data Format: $32$ bits, allowing for sufficient precision in calculations and data manipulation.

Short Program Demonstration

Arithmetic Operations:

ADD R$1,$ R$2$: Add values in R$1$ and R$2,$ store result in ACC.

SUB R$3,$ R$4$: Subtract value in R$4$ from R$3,$ store result in ACC.

Logic Operations:

AND R$5,$ R$6$: Perform bitwise AND on R$5$ and R$6,$ store result in R$5.$

OR R$7,[$Address$]$: OR value in R$7$ with memory value at $[$Address$],$ store result in R$7.$

NOT R$8$: Perform bitwise NOT on R$8,$ store result in R$8.$

I$/$O Operations:

IN $[$DeviceID$],$ R$9$: Read input from I$/$O device identified by $[$DeviceID$],$ store in R$9.$

OUT R$10,[$DeviceID$]$: Write value in R$10$ to I$/$O device identified by $[$DeviceID$].$

Justification of Architectural Choices

RISC$-$like Processor: Offers simplicity and focuses on fundamental instruction execution, ideal for educational purposes.

Unified Memory Model: Simplifies memory management and instruction fetching, making it easier to understand program execution flow.

Minimal Instruction Set: Covers essential operations for basic programming, ensuring that students can grasp the core concepts of machine instruction execution without being overwhelmed.

Instruction and Machine Cycles Explanation

For each operation, the processor goes through a series of steps:

Fetch: Instruction is fetched from memory into the instruction register, incrementing the IP$.$

Decode: Opcode is decoded to determine the operation, and operand addresses are calculated if needed.

Execute: Operation is executed using operands from registers or memory, and results are stored accordingly.

Write$-$back: Results of the operation $($if any$)$ are written back to the destination register or memory.
