  1. The Tron Project • Angelo G. Gagliano • Microprocessors • Date: 5/13/02

  2. More than just a Great Movie! • It is the acronym for a project that began in June 1984 by Professor Takeshi Sakamura of the University of Tokyo • TRON stands for The Real-time Operating System Nucleus.

  3. The TRON Project Basic Goal: • To create a system of devices that can be easily integrated with one another. • This is attempted with the use of an open designed architecture (TRON) that would exist as a distributed network of TRON based designs. • TRON does not actually create any products, just open specifications.

  4. 5 Subprojects of TRON • ITRON: Industrial TRON • CTRON: Communication/Central TRON • BTRON: Business TRON • JTRON: Java Technology on TRON • TRON VLSI CPU

  5. Industrial TRON • A real-time multitasking kernel specifications for embedded control applications • Currently used in over 30% of Japanese embedded systems (as of March 2002) • The open standard has allowed for a total of 50 registered implementations of the ITRON specifications.

  6. Communication / Central TRON • OS Specifications to be used in communications and information processing systems • The goal is to be the core of telecommunications networks and multimedia communications

  7. Business TRON • Specifications for systems that interact with humans. • The goal is to have devices that can be easily used by anyone - from development to actual user interfaces (The TRON writers compare this to how we use automobiles) • Code space capacity of 1.5 million characters to support a large number of languages

  8. Java TRON • Standards for communication interface between real-time tasks of the ITRON specification and Java applications. • Java objects are created that are mapped to ITRON kernel objects/tasks

  9. TRON VLSI CPU: • The Main component of the TRON Project: The TRON Very Large-Scale Integration CPU • CISC based chip • 32-bit microprocessor • 16 general purpose registers • 9 control registers

  10. TRON VLSI CPU Continued... • Total of 6 levels of implementation: The Microprocessor manufacture can decide how much they need to implement • Average number of instructions among the levels: 99 • 5 Stage pipeline

  11. TRON VLSI CPU Goals / Issues • The main purpose of the chip is to be used as a cheap low-power microprocessor that can be networked with others of its type to create a powerful distributed system. • Unfortunately, it has taken me a week to concede to the fact that the documentation on how this network technically would work is still in Japanese.

  12. TRON CPU History • First TRON CPU was the Gmicro/200 in 1988 • Toshiba Corp., Hitachi Ltd., Fujitsu Ltd., and Mitsubishi Electric Corp., Matsushita Electric Industrial Co. have followed with additional implementations.

  13. TRON Integration • All of these subprojects exist to handle the different ways in which we use technology. • Smart devices (or intelligent objects as referred to in the TRON Projects) can easily be integrated if based on the architecture.

  14. Integration @ Work • Someone will create the CPU based on the TRON VLSI CPU. • The manufacture will decide how it is implemented (how to implement the TLB & MMU, number of pins to use, etc.) • Someone else will create the OS based on the ITRON, BTRON, or CTRON specifications.

  15. Integration @ Work Continued... • The decision will be made based on the type of device: • BTRON specifications will be used for applications that will require human interaction like PDA’s, home electronics, etc. • ITRON would be used to provide an multitasking OS to support C/C++, Java. Ada. And other popular languages • CTRON would be used to provide details for communication systems.

  16. What Makes TRON Interesting • A collection of real-time systems that can be easily integrated. • Example of the project at work is called the TRON house; a very expensive and elaborate house of integrated gadgets in an expensive area of Tokyo.

  17. Problems of the TRON Project • Although the now 18 year old project is definitely still alive and is used in a large number of devices in Japan, support from other countries has been slow to null. • Some documentation still only in Japanese like the main TRON Project PDF (making this research project a lot harder than it should have been)
