[CCID news] Sun Microsystems announced the upcoming release of ultrasparc iv + chip. The IV + chip-based server runs twice as fast as the ultrasparc IV server. The new chip, codenamed "Panther", will detail details about the high-end processor on Tuesday.
Like the current ultrasparc IV chip, ultrasparc iv + is impl
chip design is divided into front-end design and back-end design, front-end design (also known as logical design) and back-end design (also known as physical design) does not have a uniform strict boundaries, involving the process-related design is the back-end design.

Chip design This business, from the big aspect, mainly divided into analog and digital two chunks, and each large and sub-front and back end, I think most of the students on this is definitely very clear, the following on the digital circuit chat chip design Some things, is the chip design has what to do, this is not a complete system introduction, Just a persona
As the main control unit of the embedded system-single-chip microcomputer, its software is often a micro real-time operating system, and most of them are specially designed for a certain application. The system program is capable of real-time process control or real-time information processing. It must be able to respond to random external events in a timely manner and quickly process the events. However, the time-sharing operating system divides the

About the NIC chip problem on the motherboard
To the Internet users know that the Internet is used to dial, so the network card is not familiar to people who used to surf the internet, and now do not need to dial, so the Internet card became an essential hardware, and the motherboard on the card chip has become an important part, together to understand:
Motherboard card
The continued popularity of the smartphone market has also escalated the battle for upstream processors. Recently, the traditional chip manufacturers- -Broadcom, Inc., announced that it will exit the mobile phone communication chip market (baseband processor chip), let people sigh unceasingly. But at the same time, the "upstart" Intel is accelerating the layout
Learning to use single-chip microcomputer is to understand the hardware structure of single-chip microcomputer, as well as the application of internal resources, to learn initialization settings of various functions in the compilation or C language, and to implement programming of various functions.
Step 1: use of digital I/O

0 Introduction
There are many types and styles for the design and development of digital voltage meters. Traditional Digital Voltage meters have their own characteristics and are suitable for manual measurement at the site, however, to complete remote measurement and further process the measurement data, the traditional digital voltmeter cannot be used. Therefore, a digital voltmeter Based on PC communication is designed in this paper. This table can transfer measurement data and process measure

It has no real register, and i
Recently, Tsinghua Purple, Wuhan New core in the field of memory chips frequently, so that we look at the previously neglected memory chip. For a long time, in the CPU,GPU, baseband and other "advanced" chip spotlight under the cover-up, memory chip has been in obscurity, however, any one involving digital IC products, small to the bank card, big to the server, i
Introduction
Flash Memory, also known as flash memory, is a new kind of non-volatile semiconductor storage developed in the late 1980s S. It has the features of Ram and Rom, which can be erased and rewritten online, and keep data intact after power loss.
Nor flash is the first kind of flash memory. Compared with other types of flash memory, nor flash has the following advantages: high reliability, fast random reading speed, and single-byte or single-word programming, allows the CPU to directly r
