Sistem Operasi || Praktikum Model Pemrograman 1 Sistem Operasi Menggunakan OS Simulator

Summary

This transcript details a practical session using the CPU-Z simulator to explore key operations in an operating system. The narrator, Tanto Nugraha from the Indonesian University of Education, walks through various tasks such as data transfer, arithmetic operations, comparison instructions, and program control using the simulator. The video covers instructions like moving data to registers, adding values, and manipulating program stack and counters. The demonstration includes observing register values, performing comparisons, and executing conditional jumps. Throughout the session, the narrator explains how these actions contribute to understanding basic operating system functions.

Takeaways

• 😀 Introduction to the speaker, Tanto Nugraha, from the Multimedia Education study program at the Indonesian University of Education.
• 😀 The practicum involves using the Safeway OS simulator to understand various CPU operations and instructions.
• 😀 The CPU-Z simulator interface includes several panels such as the Seven installation panel, program list, control program section, and special CPU register panel.
• 😀 The first task in the practicum is a data transfer process, where the speaker moves a number (5) to the r0 register using the move instruction.
• 😀 The second task involves moving another number (8) to the r1 register and observing how the values are reflected in the register tables.
• 😀 An arithmetic instruction is created to add the contents of the r0 and r1 registers, storing the result in the r0 register.
• 😀 The practicum includes creating a step pointer instruction to push data to the program stack, which changes the value of the SP register.
• 😀 Comparison instructions are implemented to compare values in r0 and r1, and the speaker demonstrates how to observe the status bits in the status register.
• 😀 Conditional jump instructions are executed using the JMP instruction, where the program counter (PC) register value is updated.
• 😀 The practicum also covers using the pop instruction to retrieve values from the program stack and store them into registers like r02 and r03, observing changes in the SP register.
• 😀 The final instructions focus on comparison and conditional jumps, ensuring that if certain conditions are met, the program will jump to specific instructions.
• 😀 The session ends with a reflection on the instructions and operations carried out during the practicum, followed by a polite closing and apology.

Q & A

What is the purpose of using the CPU-Z simulator in this practicum?

The CPU-Z simulator is used to simulate an operating system environment for the practicum. It allows for the practice and understanding of data transfers, arithmetic processes, and various instructions that are fundamental in operating system operations.

What are the main panels in the CPU-Z simulator?

The main panels in the CPU-Z simulator include the installation panel, program list, control program panel, special CPU register panel, and general tool brush panel.

What function does the control program panel serve in the CPU-Z simulator?

The control program panel is used to run programs step-by-step or directly, allowing users to control and execute each sequence of instructions.

What is the role of the 'special CPU register' panel?

The special CPU register panel displays various registers such as A, B, C, SPS, and RBR. It is crucial for observing and manipulating the state of the CPU during simulation.

How is data transferred between registers in this practicum?

Data transfer between registers is done by writing specific instructions, such as moving the number 5 to the R0 register and moving the number 8 to the R1 register, using the 'move' instruction in the simulator.

What happens when the arithmetic process is performed in the practicum?

In the arithmetic process, an addition instruction is created to add the contents of R0 and R1. The sum is then stored in the R0 register, with the example showing 5 + 8 = 13.

What is the program stack used for in this practicum?

The program stack is used to store values temporarily. In the practicum, values from registers are pushed onto the stack and later popped back into registers for further operations.

What is the purpose of the comparison instruction in this script?

The comparison instruction is used to compare the values in two registers, like R0 and R1. It sets flags in the status register that help in determining the outcome of conditional operations.

What is the significance of the Program Counter (PC) in the CPU-Z simulator?

The Program Counter (PC) keeps track of the address of the next instruction to be executed. In the practicum, conditional clocking is used to jump to specific instructions based on the comparison of register values.

What does the 'pop' instruction do in the practicum?

The 'pop' instruction is used to retrieve the top value from the program stack and load it into a specified register. This allows for manipulating the program stack and continuing the simulation.
