An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
The Intel MCS-51 (commonly termed 8051) is a single-chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton. [1] [2] Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives remain ...
Microcontrollers have proved to be highly popular in embedded systems since their introduction in the 1970s. Some microcontrollers use a Harvard architecture: separate memory buses for instructions and data, allowing accesses to take place concurrently. Where a Harvard architecture is used, instruction words for the processor may be a different ...
Nucleus RTOS is a real-time operating system (RTOS) produced by the Embedded Software Division of Mentor Graphics, a Siemens Business, supporting 32-and 64-bit embedded system platforms. The operating system (OS) is designed for real-time embedded systems for medical, industrial, consumer, aerospace, and Internet of things (IoT) uses.
The ARM architecture dominates the market for low-power and low-cost embedded systems (typically 200–1800 MHz in 2014). It is used in a number of systems such as most Android -based systems, the Apple iPhone , iPod Touch , iPad , Apple Watch , and Apple TV , Palm , Microsoft Windows Phone (former Windows Mobile / Windows CE), RIM devices ...
The Architecture Analysis & Design Language is derived from MetaH, an architecture description language made by the Advanced Technology Center of Honeywell. AADL is used to model the software and hardware architecture of an embedded, real-time system. Due to its emphasis on the embedded domain, AADL contains constructs for modeling both ...
Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.
A network on a chip or network-on-chip (NoC / ˌ ɛ n ˌ oʊ ˈ s iː / en-oh-SEE or / n ɒ k / knock) [nb 1] is a network-based communications subsystem on an integrated circuit ("microchip"), most typically between modules in a system on a chip ().
