Embedded accounting machines are ubiquitous in everyday equipment, office supplies, cars, industry, medical and agriculture. From calculators to telephones, cameras, elevators, traffic lights, plant controllers, and nuclear power plant control systems, there are physical embedded systems in virtually everything in modern equipment. What are they? How do they work? What are the procedures for using the embedded computer?
Embedded computers can be broadly defined as any accounting machine that uses computer hardware and software to perform a specific function, as opposed to the general processing performed by modern desktop computers and servers. The specialized features of these embedded architectures allow them to take advantage of a lightweight software or firmware base and on-board ASICS to minimize power consumption and hardware requirements.
Modern processors include numerous integrated accelerators for encryption, data and video graphics processing.
Most embedded computers have almost everything in their hands on a single PCB or motherboard. Because with fewer replaceable components, such as RAM, CPU, and storage, embedded boards look very different from traditional consumer motherboards. Generally, there are no slotted components on embedded boards, and most of the components are soldered to the CPU.
The demarcation characteristics of embedded computers can be divided into four aspects
1. Small size: A single high-density PCB is generally selected for planning to maximize the space power.
2. Lower Power Components: Energy-efficient processors with lower TDPs for forced or minimal cooling to eliminate fans and moving components.
3. Minimal upgradeability or scalability: Few slot components constrain their upgradeability and scalability beyond their initial planning and function.
4. Low hardware cost: The expansion slot for soldering components is abandoned, while the SoC reduces the overall cost and component complexity. Optimized for low-cost mass production of these embedded boards.
Embedded systems need to be optimized for low power consumption, code complexity, size, weight, and cost. Many people even lack a dedicated on-board user interface (mouse, keyboard, and screen) that is largely manipulated through a remote management interface, secure shell, or even a direct firmware update.
A typical embedded computer is mainly composed of the following elements:
CPU and micromanipulator (one or more): Logic gates containing transistors and arithmetic processing units (ALU) packed within a single chip – they are embedded architectures. The brains of the processors and manipulators are responsible for the operation and accounting of the main system, obtaining data from the cache (L1, L2, L3) and the system memory (RAM) at all levels.
CPU Cache (L1, L2, L3): Because it is optimized for extreme speed, it takes up a significant portion of the die and uses a single-level cell architecture (SLC) to increase speed. This means that each cell includes 1 bit of data, which is due to this data and the high transistor count of this high-speed memory. On the CPU, this cache is limited to a very small amount, during which the L1 cache is the fastest, but it is limited to 00 KB, L2 1024KB and L3 2-16MB. The speed of this cache and its proximity to the CPU is critical to the performance of the processor.
Fabric Memory (RAM): An order of magnitude slower than cache, but many times faster and more resilient than non-volatile storage such as hard disk drives and solid-state NAND drives, Fabric Memory is used to store running programs for quick access and transfer to the processor cache. This memory is written thousands of times per minute when using a program to move data around and perform complex operations, so it doesn't suffer from unit degradation and limited write/erase cycles.
Non-volatile storage: Hard drives, SSDs, NAND, and other non-volatile storage technologies are the slowest but largest storage in the stack. Larger system files and data files are stored here for normal use of the system.
CMOS - RAM: This component is responsible for storing important system configuration and real-time information. Powered by a small button battery, it can turn off the power of the system without losing its timekeeping and system wake-up functions.
I/O Ports: Any connection from the Ethernet RJ45 port to the 3.5mm audio jack falls into this category. They enable the system to withstand and handle external inputs through standardized interfaces such as USB and HDMI.
Use examples
There are many examples of how embedded computers can be used, ranging from small, single-purpose devices such as calculators to complex systems such as passenger car cruise control. They are now ubiquitous and inevitable in our daily lives. Such as calculators, digital cameras, car embedded systems (ABS interrupts, car alarms, engine sensor systems), active vending machines, elevators, photocopiers, printers, GPS, network equipment (switches, modems, routers, access points), video games
Household appliances (AC, microwave, refrigerator).
Some embedded systems are planned to operate under more extreme conditions, such as industrial-grade systems, which require wide operating temperatures, electric field isolation, vibration resistance, and more. The enterprise-level system requires critical task services with accounting ability, reliability, and redundancy.
Machine Vision: Encompasses all industrial and non-industrial uses, where the combination of powerful hardware and practiced software provides operational guidance for devices that capture and dissect image-sensing data.
Plant Automation: Use real-time or near-time accounting technology to manipulate and supervise industrial processes, equipment and machinery. In general, any duplication of functions is ideal for initiative, allowing the system to operate through a well-defined process that minimizes human interaction.
Digital Signage: Digital content that is broadcast through screens such as LED panels, high-resolution displays, and projectors.
We can see that almost all electronic products in the days rely on embedded systems. With reliable, embedded, low-cost planning, they're always on.
Most of the time they are hidden behind the façade of panels and bright light, invisible to the naked eye, but they power all modern technology and interconnected systems. The intelligent use and advancement of embedded smart devices will continue to improve the ability and power for our days.
