An embedded system has 3 components: It has the hardware. Designers have traditionally used a hardware description language (HDL) such as VHDL (Figure 4) or Verilog to design the FPGA configuration. This FAQ will introduce you to the concept. It has software program. The hardware is kept as simple and fast as possible. Repeat the patern for each main function of the system. The main difference between computer hardware and software is that hardware is a physical component of a computer, whereas software is a program that relies on the hardware to function. For example, in addition to the concept of software architecture, we may encounter concepts such as enterprise architecture, system architecture, organizational architecture, information architecture, hardware architecture, application architecture, infrastructure architecture, and so on. This architecture model provides Software Developers to create Reusable application/systems with maximum flexibility. wired or wireless). Workflow / Sequence 2. Justification of architecture. Describe here the rationale of the hardware / software architecture in terms of capabilities: Hardware Architecture Example (geographical level mapping of servers) Tuesday, August 18, 2009 at 9:11PM. The process is similar to a software development cycle except that the goal is to architect the hardware itself rather than a set of instructions to run on a predefined hardware platform. Defining Network Architecture. It is also called “Multi-Tier Architecture”. An example configuration is shown in Figure 14-1. Particular hardware configurations depend on the specific needs of the network, and are worked out in the dimensioning and capacity planning stage. Network architecture refers to the layout of the network, consisting of the hardware, software, connectivity, communication protocols, and mode of transmission (i.e. System architecture capabilities. Network architecture is the logical and structural layout of the network, consisting of transmission equipment, … A given complex instruction can be performed by a sequence of much simpler instructions. It has an actual real-time operating system (RTOS) that supervises the utility software and offer a mechanism to let the processor run a process as in step with scheduling by means of following a plan to manipulate the latencies. For example, many processors have an xor (exclusive OR) instruction for bit manipulation, and they also have a clear instruction to set a given register to zero. I have put down my thoughts in the architecture discussed in the blog. The Architecture diagram can help system designers and developers visualize the high-level, overall structure of their system or application to ensure the system meets their users' needs. COMPONENTS OF EMBEDDED SYSTEMS ARCHITECTURE. A word processing program, for example, relies on hardware to … For example, the user queries data, what happens, from his terminal to the database. Hardware architecture may be implemented to be either hardware specific or software specific, but according to the application both are used in the required quantity. In N-tier, "N" refers to a number of tiers or layers are being used like – 2-tier, 3-tier or 4-tier, etc. First one is RISC and other is CISC. You can also use architecture diagrams to describe patterns that are used throughout the design. As far as the processor hardware is concerned, there are 2 types of concepts to implement the processor hardware architecture. Smaller systems where the different layers exist in the same physical servers are also possible. CISC Architecture
