Shenzhen embedded operating system OK? Shenzhen Education Embedded Training Center teacher said that the real development of embedded computers after the advent of microprocessors. In November 1971, Intel successfully integrated the arithmetic and controller circuits, introduced the first microprocessor Intel 4004, followed by the introduction of many 8-bit, 16-bit microprocessors, including Intel 8080/8085, 8086,motorola 6800, 68000, and Zilog

public, and more attention should be paid to applications with microprocessor. 2. How high is the frequency?When the signal goes up/down For digital circuits, the key is to look at the steep edge of the signal, that is, the time when the signal rises or drops,According to the theory of a very classic book "high speed Digtal design>, the signal is increased from 10% to 90%, and the time delay of the wire is less than 6 times. It is a high-speed signal

relationship with the specific resistance value, but the package size is related to the power. Generally, the package size is 0201 W. 0402 1/16 million 0603 1/10 million 0805 1/8 million 1206 1/4 million The relationship between the shape size and encapsulation of the capacitor resistance is as follows: 0402 = 1.0x0.50603 = 1.6x0.8 0805 = 2.0x1.2 1206 = 3.2x1.6 1210 = 3.2x2.5 1812 = 4.5x3.2 2225 = 5.6x6.5 2.

Sort the information according to arm official and online documents. Let's take a picture of the Architecture first. ARM microprocessor Series ARM microprocessor currently includes the following series, as well as other manufacturers based on the ARM architecture of the processor, in addition In addition to the common features of the ARM architecture, each series of ARM

dominated by 32-bit CPU cores. The CPU cores designed by arm are commonly known as "ARM chips ", however, strictly speaking, an ARM chip should be a single-chip microcomputer designed with the CPU core of the arm. An SoC chip made with the CPU core of the arm is generally not called an ARM chip.Therefore, the ARM chip mentioned by the landlord is an advanced general-purpose microcontroller.DSP = digital signal processing, that is, digital signal processing. Like "Arm chip", "DSP chip" is common

One:CISC (Complex instruction Set computer) complex instruction computer CISC is the basic processing part of a desktop computer system, and the core of each microprocessor is the circuit that runs the instruction. A command consists of multiple steps to complete a task, transferring the value into a register, or adding an operation. CISC is a microprocessor that executes a complete set of computer instruct

[From: an in-depth understanding of Linux kernel] Linux tries to keep a clear line between hardware-independent source code and hardware-related source code. To achieve this, the arch and include directories contain 23 sub-directories to correspond to different hardware platforms supported by Linux. The standard names of these platforms are as follows: Alpha HP's Alpha workstation was first owned by digital, and later belongs to Compaq, which is no longer produced. Arm, arm26 ARM-based computer

competitive in this rapidly growing market. However, users benefit from low prices. Many of the structural features of early PCs remain in modern PC systems. For example, Intel's most advanced Pentium Pro processor retains the Intel 8086 addressing model. When Linus Torvalds started to write Linux, he chose Intel 80386 PC, which was the most widely used and reasonably priced at the time.. 1 typical PC motherboard. From the outside of the PC, the most striking is the chassis, keyboard, mouse and

, it consists of analog signal conditioning circuit, A/D conversion circuit, display circuit and 485 communication circuit. The signal must be processed before it enters the/D converter. analog signal processing is one of the important factors affecting the system performance. signal quality should be taken into consideration during design to improve the signal-to-noise ratio and minimize distortion. In the design, the potentiometer is used in the conditioning circuit for fine-tuning, and the vo
