• Small and stable [micro]kernel: stable operating environment

[Table Of Contents:] Compatibility

1. Compatibility of operating systems
2. Issues on compatibility
3. Tmax approach to compatibility

Compatibility Of Operating Systems

• Application compatibility
  • Able to use existing various applications and data without change
• Device driver compatibility
  • Able to use existing various device drivers without change

Issues On Compatibility

• The compatible [application programming] interface is crucial for application and device driver compatibility

Tmax Approach To Compatibility

Tmax Window9 has expanded or restructured the core for sake of compatibility with existing OSes, and minimized the compatibility layer itself with optimized subsystem solving the performance problem.

• If OS core didn’t change and only compatibility layer handles [API]:
  • Increased complexity of compatibility layer
  • Performance problem
• [Solution]
  • Expanded and restructured OS core adequate for compatibility mechanism
  • Removed complexity of compatibility layer
  • Removed performance problem due to compatibility

We has defined subsystem feature set of Tmax Window9 from complete analysis of existing OSes, and designed it to provide features efficiently.

• Subsystem feature definition from complete analysis of MS Windows, Mac OS [X], Linux
• Expansion of kernel for performance and security
• Realizing small and lightweight compatibility layer

What Is Small Kernel?

Kernel is highly complex and hard to develop, so we made the kernel small and are able to get convenience of application programming, thus making the entire system stable.

[Diagram omitted]

Pros Of Small Kernel

Macrokernel stops or loses the data when error is occurred, but microkernel only terminates the application in question and can remain stable.

• Macrokernel
  • If an error occurs in kernel level, the entire system stops or user data is lost.
  • Very big and complex features like window manager and graphic device driver reside in kernel level and so it is unstable.
• Microkernel
  • Only the application caused the error is terminated.
  • Only the minimal feature set is in kernel level, all others are in user level.

Reusability Of Kernel

Tmax kernel has small components implementing core featuers, so they can be reused later.

[Diagram omitted]

Synchronization

Tmax Window9 supports event, semaphore and mutex in kernel level among many features required for synchronization, and others use these [primitives] or are implemented in user level.

2. Multiple OS in many aspects

Idea Of Multiple OS

Tmax Window9’s API is designed to support both MS Windows and Linux’s one, making it platform-dependent.

[Diagram omitted]

Multiple OS In Many Aspects

Via Tmax Window9, developers don’t have to design same application for [many] platforms, users can use applications for various platforms.

• [Tmax Window9] removing platform dependency
  • Developers
    • Removes redundant tasks for each platforms
    • OS provides platform independency
  • Users
    • Single OS running every application based on Windows and Linux

Requirement For Data Management

It is hard to meet various requirements for data management per application.

• Application requirement
  • Sharing the data
  • Minimizing redundancies in the data
  • Keeping the data integrity
  • Keeping the data secure
  • Recovery for accident
  • Adapting constant changes

Data Management In Tmax Window9

Tmax Window9 bundles proved Tibero DBMS, so it can solve various application requirements and manage the data stably.

• Stable data management with embedded DB
  • Bundles proved Tibero DBMS
  • Data management via Tibero
  • Ability of stable data management
  • Provides DB manager for management
  • Ability of handling huge dataset
