simple operating system by java

it is a java program

The purpose of this programming project is to gain some experience involving the design of a few OS components by simulation. These components include CPU management and scheduling, process management, system queues, system statistics gathering and reporting.

System Description

1. The Available Hardware

a. A single CPU.

b. One I/O Device.

c. Unlimited amount of Main and Secondary storage.

d. System Timer and all necessary support.

2. The User Processes

All processes created in this system fall under any one of the following types:

Type-1: Consists of:

10 CPU bursts of the following lengths: (1,2,1,1,1,3,1,2,2,1) Time Units,

9 I/O bursts of the following lengths: (6,4,10,3,5,3,2,10,6) Time Units.

Type-2: Consists of:

15 CPU bursts of 50 Time Units each, and

14 I/O bursts of 150 Time Units each.

Type-3: Consists of:

12 CPU bursts of 1000 Time Units each, and

11 I/O bursts of 5 Time Units each.

Type-4: Consists of:

A repeated pattern of (CPU, I/O1, Think, I/O2), where:

Each CPU burst takes 3 Time Units,

Each I/O1 burst takes 3 Time Units,

Each I/O2 burst takes 10 Time Units,

Think time takes 60 Time Units.

Any one of the types above can be created at any time. Type-4 has a maximum of N instances. No new processes of this type can be created after this limit. Processes of Type-1 to Type-3 terminate after executing their last CPU burst, while processes of Type-4 never terminate, they cycle through their pattern forever. Assume that a process in its think period stays out of the Ready Queue, say in a special list.
