In this days, the concept of time-to-market is important in embedded systems in consumer electronics. According to the short time of development period, it is also important in development of Software Development toolkits (SDKs). However, it is not improved to the development time of SDKs specialized in new processors. In this point, the Architecture Description Language (ADL) is an alternative to relieve the pain of building the SDKs as the required SDKs can be automatically generated from ADL for the processor. In this paper, we automatically generate SDKs specialized in processors using GNU Binutils. Through this research, we can more easier and faster produce the SDKs such as assembler and linker than by using handcrafted code.

Application specific instruction-set processor (ASIP) is a suitable design choice for system designers who seek both flexibility to handle various applications in the domain together with the performance. Successful development of an ASIP, however, requires a software development kit (SDK) to be provided along with the processor. Synopsys Processor Designer is an ASIP development tool, which takes as input a set of files written in a high-level architecture description language called LISA (Language for Instruction Set Architecture), and generates SDK as well as RTL. Recently, they have added support for the generation of LLVM compiler backend, though some manual work is required. In this paper, we introduce some details in porting LLVM compiler to a custom processor architecture in Synopsys Processor Designer.

Together with a new advent of embedded processor developed to support specific application area and it evolution, a new research of software development to support the embedded processor and its commercial challenge has been revitalized. Retargetability is typically achieved by providing target machine information, ADL, as input. The ADLs are used to specify processor and memory architectures and generate software toolkit including compiler, simulator, assembler, profiler, and debugger. The EXPRESSION ADL follows a mixed level approach-it can capture both the structure and behavior supporting a natural specification of the programmable architectures consisting of processor cores, coprocessors, and memories. And it was originally designed to capture processor/memory architectures and generate software toolkit to enable compiler-in-the-loop exploration of SoC architecture. In this paper, we designed the class-based ADL based on the EXPRESSION ADL to promote the write-ability, extensibility and verified the validation of grammar. For this works, we defined 6 core classes and generated the EXPRESSION's compiler and simulator through the MIPS R4000 description.

With the recent advancements of deep learning, companies such as smart home, healthcare, and intelligent transportation systems are utilizing its functionality to provide high-quality services for vehicle detection, emergency situation detection, and controlling energy consumption. To provide reliable services in such sensitive systems, deep learning models are required to have high accuracy. In order to develop a deep learning model for analyzing previously mentioned services, developers should utilize the state of the art deep learning models that have already been verified for higher accuracy. The developers can verify the accuracy of the referenced model by validating the model on the dataset. For this validation, the developer needs structural information to document and apply deep learning models, including metadata such as learning dataset, network architecture, and development environments. In this paper, we propose a description language that represents the network architecture of the deep learning model along with its metadata that are necessary to develop a deep learning model. Through the proposed description language, developers can easily verify the accuracy of the referenced deep learning model. Our experiments demonstrate the application scenario of a deep learning description document that focuses on the license plate recognition for the detection of illegally parked vehicles.

There are growing demands for improving the patient safety and the effectiveness of medical services through device connectivity and interoperability. However, integration through networking might greatly increase the complexity of the system if it is not properly designed, jeopardizing patient safety. In this paper, we codify safe medical device interaction patterns, and exploit them for the low complexity design and safety analysis of networked supervisory medical systems. We implement the proposed approach as a plug-in of Architecture Analysis and Description Language (AADL). Our implementation enables the modeling and safety analysis of medical devices and their interactions before actual development.

Software architectures may be described using text-based architecture description language(ADL). The key goals of an ADL are to communicate alternate designs between different stakeholders, to detect reusable structures, and to record design decisions. This paper provided a solution to the representation problem by creating a tool for three-dimensional representation of architectural viewpoints. The tool consisted of an architecture description language(VTADL) to first describe the software architectures and viewpoints on the architectures; and a VTADL-to-VRML translator to translate each viewpoint into a separate virtual reality world The goal of the paper was to devise algorithms for translating an ADL into effective VRML representations based on the desired viewpoint. The VRML representations were intended to enhance comprehension on the overall design and to improve communications between diverse stakeholders.
