EMBEDDED SYSTEM ARCHITECTURE
Embedded System Architecture is one of the first steps in the creation of an embedded system. It is the most important step to ensure success in meeting system goals and objectives.
The Embedded System Architecture process requires research, collaboration, innovation, and experience to lay the foundation for the design and implementation of an embedded system.
The Embedded System Architecture process should define the object or objects of the system. This defines the building blocks for the significant subjects of the system. Each building block can be decomposed into smaller subsystems. It is important to define the interaction of the objects with other systems and the external environment Furthermore, the process should characterize the lifecycle of the system. For example, the lifecycle consists of design, prototyping, testing, manufacturing, distribution, and maintenance. The lifecycle objective provides strategy for architecture and design.
The Embedded System Architecture should establish the interfaces of the system which is used to support the modeling of system. The modeling should consider various levels of abstraction and layers describing concepts such as “why”, “what”, and “how”. Should describe the properties, structure, data, states, and behavior. Should convey this information from various points of view.
Ferguson Control Systems offers services to support or perform the Embedded System Architecture process. Our team members have years of experience from previous safety-critical programs and can use this experience to help achieve success. We can work embedded within your organization for support or perform system architecture and deliver artifacts and recommendations.
Embedded System Architecture Types
Von Neumann Architecture
The Von Neumann architecture was first proposed by a computer scientist John von Neumann. In this architecture, one data path or bus exists for both instruction and data. As a result, the CPU does one operation at a time. It either fetches an instruction from memory, or performs read/write operation on data. So an instruction fetch and a data operation cannot occur simultaneously, sharing a common bus.
Von-Neumann architecture supports simple hardware. It allows the use of a single, sequential memory. Today’s processing speeds vastly outpace memory access times, and we employ a very fast but small amount of memory (cache) local to the processor.
Harvard Architecture
The Harvard architecture offers separate storage and signal buses for instructions and data. This architecture has data storage entirely contained within the CPU, and there is no access to the instruction storage as data. Computers have separate memory areas for program instructions and data using internal data buses, allowing simultaneous access to both instructions and data.
Programs needed to be loaded by an operator; the processor could not boot itself. In a Harvard architecture, there is no need to make the two memories share properties.
CISC and RISC
CISC is a Complex Instruction Set Computer. It is a computer that can address a large number of instructions.
In the early 1980s, computer designers recommended that computers should use fewer instructions with simple constructs so that they can be executed much faster within the CPU without having to use memory. Such computers are classified as Reduced Instruction Set Computer or RISC.
