ITRON
The ITRON project was the first sub-project of the TRON project. It has formulated and defined Industrial TRON (ITRON) specification for an embedded real-time OS (RTOS) kernel. Originally undertaken in 1984, ITRON is a Japanese open standard for a real-time operating system initiated under the guidance of Ken Sakamura. This project aims to standardize the RTOS and related specifications for embedded systems, particularly small-scale embedded systems. The ITRON RTOS specification is targeted for consumer electronic devices, such as mobile phones and fax machines. Various vendors sell their own implementations of the RTOS. Details ITRON, and μITRON (sometimes also spelled uITRON or microITRON) are the names of RTOS specifications derived from ITRON projects. The 'μ' character indicates that the particular specification is meant for the smaller 8-bit or 16-bit CPU targets. Specifications are available for free. Commercial implementations are available, and offered under many diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TRON Project
TRON (The Real-time Operating system Nucleus) is an open architecture real-time operating system kernel design. The project was started by Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs. For different scenarios, the need for different OS kernels was identified. (See, for example, papers written in English in TRON Project 1988 ) The Industrial TRON (ITRON) derivative was one of the world's most used operating systems in 2003, being present in billions of electronic devices such as mobile phones, appliances and even cars. Although mainly used by Japanese companies, it garnered interest worldwide. However, a dearth of quality English documentation was said to hinder its broader adoption. The situation has improved since TRON Forum has taken over the activities to support TRON Project since 2015. (See thspecification pagethat lists many English documents. ) T ...

CxProcess
CxProcess is the trademark of an image processing technology used in Minolta and Konica Minolta digital cameras. Image processing in a camera converts the raw image data from a CCD image sensor into the format that is stored on the memory card. This processing is one of the bottlenecks in the speed of digital cameras. Between 2001 and 2006, CxProcess was used in various Minolta and Konica Minolta digital compact cameras, bridge cameras, and DSLRs. In order to distinguish the image processing algorithms from the image processor, the image processor was named SUPHEED (for ''superior image and speed'') since 2003. It can be seen as the predecessor of Sony's Bionz image processor since their taking-over of Konica Minolta's camera business in 2006. CxProcess was originally introduced with the Minolta DiMAGE 5 in 2001. SUPHEED was introduced with the DiMAGE A1 in 2003, which was also the first to implement CxProcess II. Cameras such as the DiMAGE 7 series (DiMAGE 7, 7i, 7Hi), A1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-License
T-License is the software license used by TRON Forum for distributing the source code of its real-time operating systems (RTOSs) such as T-Kernel and Micro T-Kernel (often written as μT-Kernel: μ pronounced as "micro", not "mu"). The license fee is free if products are developed according to T-License conditions. The current version of T-License is version 2.2. T-License has been created to fit the need of embedded computer system market where the source code may contain information tied to proprietary hardware information. So, unlike GNU General Public License, T-License does not require the release of the (modified) source code of a program even if such a program is used by a third party. The requirement to express that the use of T-Kernel or μT-Kernel by a logo in a product somewhere on the product itself or the manual can be alleviated by a TRON Forum member. Because of this, not all products released in the market that use T-Kernel or μT-Kernel mention the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FR-V
The Fujitsu FR-V (Fujitsu RISC- VLIW) is one of the very few processors ever able to process both a very long instruction word (VLIW) and vector processor instructions at the same time, increasing throughput with high parallel computing while increasing performance per watt and hardware efficiency. The family was presented in 1999. Its design was influenced by the VPP500/5000 models of the Fujitsu VP/2000 vector processor supercomputer line. Featuring a 1–8 way very long instruction word (VLIW, Multiple Instruction Multiple Data (MIMD), up to 256 bit) instruction set it additionally uses a 4-way single instruction, multiple data (SIMD) vector processor core. A 32-bit RISC instruction set in the superscalar core is combined with most variants integrating a dual 16-bit media processor also in VLIW and vector architecture. Each processor core is superpipelined as well as 4-unit superscalar. A typical integrated circuit integrates a system on a chip and further multipli ...
