アライブビジョンソフトウェア List of Products and Services

At Alive Vision Software, we develop a vehicle ECU reprogramming (reprogram) system and new reprogramming sequences that comply with the standards of various automobile manufacturers via CAN communication. Reprogramming requires an implementation that is deeply dependent on the individual architecture of the microcontroller, as the ECU itself switches control while operating to rewrite the firmware. Our company has been responsible for low-layer development of the bootstrap section (Boot section) for numerous major automotive microcontrollers in assembly language and C language, flexibly responding to specification changes and bug fixes. Additionally, we have extensive experience in adhering to strict quality management processes using various verification tools essential for automotive software development, such as CANoe, WinAMS, and QAC.

■ Have you ever experienced setbacks with large-scale operating systems? In this seminar, we will learn the core mechanisms of an authentic real-time OS (TOPPERS/SSP) that supports "priority preemption" with a minimal configuration, running on actual hardware (Raspberry Pi) over two days (a total of 12 hours). ■ Adopting the powerful C++ bare-metal environment "Circle" This seminar is based on the open-source library "Circle," which strongly supports bare-metal development on Raspberry Pi. It comprehensively covers standard peripheral drivers such as USB, SD/FAT, networking, audio, display, and multi-core control, all abstracted as C++ classes. Participants can focus 100% on the core of OS kernel development, such as "task switching" and "mutual exclusion." ■ Cultivating "versatile" embedded engineers on-site This enables the development of dedicated machines and appliances that operate with "ultra-low latency" in the millisecond and microsecond range. Participants will learn methods to confirm low-reproducibility bugs, such as "task deadlocks," at the source level, which frequently occur in the field.

• Employee training

At Alive Vision Software, we handle the essential **"BSP (Board Support Package) construction" and "device driver development"** during the launch of new hardware. In this project, we were responsible for building a platform for hardware manufacturers in the development of radiation measuring instruments. Under the high-performance SoC "Zynq-7000" and the real-time OS "eT_Kernel," we reliably developed various drivers, including the VDMA driver for screen display, MIO driver, and GPIO driver, providing a stable operating foundation. We respond to challenges at the low layer level, such as "I want to entrust the OS porting and environment setup for new microcontrollers and SoCs" and "I lack the manpower for developing dedicated drivers for peripheral functions and display control."

• Other Software

At Alive Vision Software, we undertake commissioned work for systems without specifications and for the investigation and analysis of bugs in **"embedded systems and real-time operating systems (RTOS)"** where the frequency of reproduction is low and identifying causes is extremely difficult. In this achievement, we were officially commissioned by the OS vendor, which develops and sells the μITRON4.0 compliant RTOS "PrKernelV4," to provide advanced technical support and bug investigation for end users. In a fiber optic fusion splicer, we addressed a severe phenomenon with low reproducibility, where "the device occasionally fails to emit sound after hundreds to thousands of operations (a bug in EDMA)," by utilizing log analysis and debugger backtracing to identify an unreleased semaphore sequence in the exclusive control. We quickly implemented a solution through a provisional implementation. For challenging debugging and technical support issues that are difficult to resolve internally, such as "unexplained freezes or bugs occurring just before mass production or after the product is on the market" and "complex bugs involving OS, drivers, and hardware where the cause is elusive," please leave it to us.

• Other Software

At Alive Vision Software, we are conducting **"language porting (replacement) of PC software"** for old industrial machinery and machine tools that may become inoperable due to the end of support for operating systems and development environments. In this project, we fully migrated an in-house program written in "Fujitsu F-BASIC," which lost support on Windows 2000, to a C# environment for an automatic bending machine aimed at the stamping industry. Although there were no specifications or design documents available, we carried out the language migration by reverse engineering the old source code itself. We successfully achieved the language migration of the PC software without modifying the existing system, such as the control PIC microcontroller for the device (2-axis stepping motor control). This was a challenging program migration that two other companies had attempted in the past but failed. However, thanks to our solid deciphering skills, we succeeded in the replacement and modernized the system with additional features. If you are facing difficulties with language migration of old PC software or issues due to the lack of specifications and only have source code left, or if you have consulted other companies for migration and were turned down, please feel free to contact us.

• Other Software

The development of the "kernel itself," which is the core of real-time operating systems (RTOS), provides extremely advanced system programming techniques. We have a solid track record over many years in the development of the genuine μITRON kernel (such as the RI600 series) as an official commissioned development project from a major domestic semiconductor manufacturer (Renesas Electronics Corporation). Particularly during the launch of new microcontrollers, we have successfully completed challenging joint projects by closely coordinating with the CPU core development teams and compiler development teams within the manufacturer, releasing the genuine RTOS simultaneously with the market release of the microcontroller (MCU). If you are facing challenges that require specialized knowledge of the kernel layer, such as customizing existing μITRON kernels, porting to specific microcontroller boards, or conducting rigorous debugging around the OS, please feel free to consult with us.

• Other Software

At Alive Vision Software, we implement and port communication protocol stacks to in-vehicle real-time operating systems (RTOS) in the next-generation mobility (EV/PHV) and smart grid sectors. In this achievement, we were responsible for the implementation of the next-generation communication protocol (SEP2.0) and middleware for a dedicated ECU installed in a plug-in hybrid vehicle (PHV) as part of a smart grid demonstration project by a major domestic automobile manufacturer in the United States. If you are an automotive parts manufacturer (Tier 1 or Tier 2) or an energy-related equipment manufacturer facing challenges such as "wanting to implement advanced communication protocols in limited-resource RTOS environments (like OSEK or μITRON)" or "wanting to optimize and port open-source communication modules for your own environment," please feel free to consult with us.

• Other Software

At Alive Vision Software, we have conducted OS porting, driver development, and performance evaluation based on the real-time OS (RTOS) **"QNX Neutrino"** for "sequence controllers (industrial control devices)" that require high reliability and ultra-fast control in microsecond units. We strongly support the deployment of various models across multiple platforms spanning different CPU architectures (Intel, Arm) with our solid technical expertise in low-layer software. If you are a device manufacturer facing challenges such as "I want to port QNX to our own board (SoC) but lack the know-how," "I would like to evaluate whether real-time performance is truly achieved on the actual machine through overload testing," or "I would like to request customization of dedicated drivers to control peripheral ICs," please feel free to consult with us.

With the shift towards SDV (Software-Defined Vehicle) in automobiles, there is a rapidly increasing demand for development that allows multiple different operating systems (such as RTOS, Android, Linux, etc.) to coexist on a single high-performance SoC around the cockpit of in-vehicle systems. Our company specializes in system development that utilizes hypervisor technology to maximize hardware performance, enabling safe and high-speed communication between the safety-critical "microcontroller and control systems (AUTOSAR)" and the highly operable "display and information systems (Android OS)" without interference.
