Special Issue on VLSI Computing for Real-World Intelligent Systems

Recently, intelligent systems are desired to support human in real world such as advanced safe vehicles, home service robots, wearable computing devices, and intelligent home security systems. Such intelligent systems require extremely high computational power that exceeds that of state-of-the-art microprocessors. They also require <ul><li>Low power consumption</li><li>Low latency from input to output</li><li>Compactness</li></ul> Special-purpose processors called ""system LSIs"" play an essential role in meeting these requirements. This special issue focuses on the latest advances in system LSIs for real-world intelligent systems. One of their most important tasks is sensing environmental information such as visual information. Image and angle sensors, for example, are implemented in system LSIs. Image processing is the most time-consuming in real-world intelligent systems due to the extremely large amount of data. To overcome this problem, novel parallel architectures are presented. Electrical wires between processing modules must be minimized to make intelligent systems compact. High-speed serial data transfer is one most effective way to minimize the electrical wires. An architecture that handles processing order based on task priorities is a key to low latency. Processing of human interfaces such as face detection and speech recognition are also important factors in making intelligent systems user-friendly. I thank the authors of the articles in this issue for their effort and contributions, and the members of the Editorial Board for their cooperation.

Real World Data

Recent advance in the information technology makes our society very convenient from the viewpoint of human-to-human information communication. However, our new living style will require not only human-tohuman communication but also autonomous intelligent applications that support human beings such as an intelligent robot system, an intelligent transportation system, and a security/safe system as shown in Figure. These applications will contribute to human-oriented information society.Intelligent vehicle Home service robot Security The use of special-purpose VLSI processors capable of processing a large amount of real-world data is essential to make such applications realistic. In recent industrial trend, the special-purpose processors are called ""System LSIs"". One of the most important environmental informations in real-world applications is a vision information. The factor common to the applications is to catch an environment information moment by moment and to respond quickly with it. Therefore, it is important to make the response time from inputs to outputs very small. In this case, sensor data transfer bottleneck is not allowed as well as memory-to-PE (Processing Element) data transfer bottleneck. An image sensor signal processing VLSI together with image sensor devices is a key issue in such applications. From the above point of views, this special issue was planned to demonstrate the recent results of this area. Finally, I would like to express my appreciation to the authors for their efforts and contributions to this special issue and also the members of the Editorial Board for their cooperation.

Intelligence is one of the most important subjects in information and electronics systems. In many applications such as multi media systems, home electronics systems, factory automation systems, security systems and aerospace systems, advanced intelligent processing technologies are more required to be developed as shown in Figure. There are two approaches to increase intelligence, although they are closely related each other and may not be separable. One is an algorithm-based approach to directly increase intelligence quality. The other is a computational-power-based approach to directly increase processing performance. Even if a single operation is very simple, its repeated operations often make the processing intelligent. The problem is how to increase the computational power. It is obvious that software acceleration using general-purpose microprocessors has some limitation. Therefore, special acceleration using newly developed chips is one of the most important solutions. In particular, real-world applications need to achieve very quick response for dynamically changing real-world environment. Therefore, special-purpose processors and special-purpose accelerators or engines, are essential to make the above applications realistic. Another words, ""to realize high speed processing intelligence"" On the other hand, solid-state circuits technology enabling single-chip systems have rapid advancement resulting in dramatic improvements in both performance and cost oer function. In fact, one-giga-bit DRAMs, ten SPECint95 microprocessors containing ten million transistors are being developed by recent VLSI technology. It is no more a dream to develop practical special processors using the recent VLSI technology. Moreover, new architecture and new concept circuits have been actively studied for the next-generation integration technology. From the above point of view, this special issue was planned to demonstrate the above important area. Especially, intelligent robot is a typical class of applications, soits intelligence technology makes also any other application promising. Finally, I would like to express my application to the authors for their efforts and contributions to this special issue and also the members of the Editorial Board for their useful comments.

The new area of ""intelligent integrated systems"" has been proposed to develop one of the generic technologies for next-generation electronics and information systems. Although the interpretation may be different for individual persons, I think the area is the integration of the three concepts as shown in Figure. One is the concept of ""system on silicon"" using the integrated circuit technology. Giga-scale integration will be available in near future, so that we have to develop hardware and software architecture related to ultra highly parallel processing. Another is the concept of intelligence including physical model based computations as well as AI technology. The other is the concept of real-world applications just different from computer-world applications. The signal flow is passed through a real world, so that the performance should be evaluated as the response time or delay time. The examples are robotics, car electronics, home electronics, factory automation and so on. This special issue is planned to demonstrate the above important area, especially dedicated for robotics which is a typical example of the intelligent integrated systems. I believe that the contents of this issue give great impact on' the next-generation robot systems, and it will be a memorial publication. Finally, I would like to express my appreciation to the authors for their efforts and contributions to this special issue and also to the members of the Editorial Board for their useful comments.

Robot vision is a key technology in robotics and mechatronics for realizing intelligent robot systems that work in the real world. The fact that robot vision algorithms required much time and effort to apply in real-world applications has delayed their dissemination until new forms made possible by recent rapid improvements in computer speed. Now the day is coming when robot vision may surpass human vision in many applications. This special issue presents 13 papers on the latest robot vision achievements and their applications. The first two propose ways of measuring and modeling 3D objects in everyday environments. Four more detail object detection and tracking, including visual servoing. Three propose advances in hand feature extraction and pose calculation, and one treats video coding for visual sensor networks. Two papers discuss robot vision applications based on human visual physiology, and the last clarifies an application in optical force sensors. We thank the authors for their invaluable contributions to this issue and the reviewers for their generous time and effort. Last, we thank the Editorial Board of JRM for making this issue possible.

Security issues in high-speed data transfer between devices are always a big challenge. On the other hand, new data transfer standards such as IEEE P802.3bs 2017 stipulate the maximum data rate up to 400 Gbps. So, security encryptions need high throughput to meet data transfer rates and low latency to ensure the quality of services. In this paper, we propose a multi-core AES encryption hardware architecture to achieve ultra-high-throughput encryption. To reduce area cost and power consumption, these cores share the same KeyExpansion blocks. Fully parallel, outer round pipeline technique is also applied to the proposed architecture to achieve low latency encryption. The design has been modelled at RTL (Register-Transfer-Level) in VHDL and then synthesized with a CMOS 45nm technology using Synopsys Design Compiler. With 10-cores fully parallel and outer round pipeline, the implementation results show that our architecture achieves a throughput of 1 Tbps at the maximum operating frequency of 800 MHz. These results meet the speed requirements of future communication standards. In addition, our design also achieves a high power-efficiency of 2377 Gbps/W and area-efficiency of 833 Gbps/mm2, that is 2.6x and 4.5x higher than those of the other highest throughput of single-core AES, respectively.

Robot vision is an important robotics and mechatronics technology for realizing intelligent robot systems that work in the real world. Recent improvements in computer processing are enabling environment to be recognized and robot to be controlled based on dynamic high-speed, highly accurate image information. In industrial application, target objects are detected much more robustly and reliably through high-speed processing. In intelligent systems applications, security systems that detect human beings have recently been applied positively in computer vision. Another attractive application is recognizing actions and gestures by detecting human – an application that would enable human beings and robots to interact and cooperate more smoothly when robots observe and assist human partners. This key technology could be used for aiding the elderly and handicapped in practical environments such as hospital, home, and so on. This special issue covers topics on robot vision and motion control including dynamic image processing. These articles are certain to be both informative and interesting to robotics and mechatronics researchers. We thank the authors for submitting their work and for assisting during the review process. We also thank the reviewers for their dedicated time and effort.
