the main slice ICW3 6.15 from the format of the slice ICW3S7~s0 corresponds to the IR7~IR0, if the main piece IRi(i=0~7) is connected from the chip on the pin, then si= 1, otherwise si= 0. ID2~ID0 is the identification code from the chip to the main piece IRi . For example, ID2~ID0 should be set to 010,d7~d3 unused when the interrupt request signal int from the slice is connected to the IR2 of the main slice, typically set to 0. In the interrupt response, the main slice through the Cascade

operating system, and an application software system. It is a "device" that can work independently ".Embedded systems include almost all electrical equipment in life, such as PDAs, mobile computing devices, TV set-top boxes, mobile Internet access, digital TVs, multimedia, automobiles, microwave ovens, digital cameras, home automation systems, elevators, air conditioners, security systems, vending machines, cellular phones, consumer electronic devices, industrial automation instruments, and med

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

tries to call a method on the object or activates the object from the client. Now, any client that knows the object URI can useChannelServicesRegister the channel and callNew,GetObjectOrCreateInstanceActivate the object to obtain a proxy for the object. The following code snippet shows an example of this operation: ChannelServices.RegisterChannel(new TCPChannel); HelloServer obj = (HelloServer)Activator.GetObject( typeof(Samples.HelloServer), "tcp://localhost:

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

physical memory managed by hardware. The operating system uses the memory management unit of the microprocessor to process real-time conversion between virtual addresses and physical addresses. The advantage of this virtual memory method can be seen from the complex address space of MS-DOS systems. Once the requested Ram exceeds the 640-kb limit originally designed by the PC, the programmer will have to make plans like expanding the memory to increas

We need to sort out some theoretical or superficial knowledge, so we have time to sort out this rough comparison, let's take a look at the features of these two mainstream processors from the other side! DSP: DSP ( digital singnal processor ) is a unique microprocessor. It has its own complete command s
