Acorn Logic Technology
Keeping Embedded Development Connected From Concept To System

Embedded development often requires decisions across hardware, firmware and application software to remain closely aligned. Acorn Logic Technology has built its approach around that connection. President and CEO Yuichi Kawamura personally handles client projects, giving him oversight of the system from the initial concept through development and testing.

“Since a single person is in charge of the entire system, the discrepancies that often arise during development do not occur,” says Kawamura.

The model gives him a direct view of technical feasibility before development gets underway. He studies the technologies involved, conducts preliminary experiments when required and considers alternative approaches early. For clients, the process means a rough concept can be examined, refined into specifications and carried into development by the same engineer.

Turning Early Ideas Into Engineering Specifications

Acorn Logic Technology frequently works with clients at the R&D stage, when a project may begin as a concept. Kawamura discusses the intended application, evaluates feasible methods and determines the specifications and features needed to turn the idea into a working system.

The company’s engineering capabilities cover electrical circuit design and PCB layout using PADS Flow. Software development primarily uses C, C++ and C#, while firmware work extends across microcontrollers, single-board computers and FPGAs. Windows-based application software is also developed for operational testing.

The combination has supported projects ranging from standalone test equipment for components installed on small satellites to systems used to test small-satellite control systems. Other R&D applications include multi-channel three-axis vibration meters, signal waveform measurement equipment and light transmittance measuring equipment.

Working Within The Hardware Available

A stepper-motor control project demonstrates how that approach works when engineering constraints are fixed from the outset. The system required a predetermined 16-bit microcontroller, yet the application demanded smooth, error-free control, high numerical precision and sufficient rotational speed.

The technical challenge was closely linked to processing speed. More precise calculations required additional processing time, while calculation speed directly affected the motor's maximum rotational speed. Because the microcontroller had been specified by the customer, the hardware itself could not be changed.

Kawamura applied existing mathematical algorithms as needed and devised a calculation method that accelerated processing while maintaining the required precision. The approach enabled the system to achieve the required rotational speed while retaining the predetermined hardware.

Designed For Research And Development

The company's systems are primarily created to support customer R&D instead of products intended for the open market. Ease of use therefore carries particular importance. Researchers need systems that allow them to conduct tests, evaluate results and continue their development work without unnecessary complexity.

Acorn Logic Technology also considers scalability during the initial hardware and software architecture. Architectural decisions can leave room for additional features and changes as a project develops.

Support continues according to the requirements of each engagement. The company accepts inquiries about completed deliverables and can undertake modifications separately. Some projects involve ongoing support arrangements, while Kawamura may attend operational testing and resolve issues directly.

Where Technical Continuity Becomes Customer Value

Astroscale Japan Inc., EMT Co., Ltd. and research institutions are among Acorn Logic Technology's clients. Repeat engagements have followed as clients return with new requirements and projects that benefit from detailed consultation, feasible proposals and systems designed around their intended use.

Kawamura's role remains central to that relationship. A client can bring a rough concept, discuss its requirements in detail and work with the same engineer as the project moves into specifications, development and testing. The continuity keeps technical decisions closely tied to the original purpose of the system while allowing issues to be addressed as the project progresses.

Acorn Logic Technology's combination of technical continuity, specialized R&D experience and practical problem-solving provides the foundation for its recognition as Top Embedded Systems and Applications Development Solutions in APAC 2026. The recognition reflects an approach built around one engineer's involvement across the development process, careful evaluation of technical constraints and systems designed to support the people conducting the work.
