With the development of PowerPC, the use of PowerPC architecture of the processor has formed a huge family, in communications, industrial control, aerospace defense and other requirements of high-performance and high reliability of the field has been widely used, is a "noble chip." At present, there are few Chinese materials to elaborate the PowerPC family pedigr

Motorola is like a warning story that tells people how a company gets lost after it reaches its peak. Motorcycles have been booming since the middle of the 1990 s. In order to recover the decline, motorcycles have also carried out two large-scale self-help reforms in the next 10 years. However, unfortunately, neither of them has been necessary, it is even counterproductive. "After entering the 'geographic review ', the company needs a strong figure

Article Title: Analysis and Application of Motorola microprocessor bootloader. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Introduction ?? Bootloader is a program used to complete system startup and system software loading. It is a middleware software between the underlying hardware and the upper-layer applicat

As a dynamic between the U-boot and the Linux kernelInterface, this paper describes the data storage format of the device tree and the source code description syntax, and the

flooded the market, best-selling and not selling, people are dazzled by confusion. There was a big problem--it was a lot of trouble to have our phones and PDAs at the same time--even if they were thin and short. Wouldn't it be more convenient to have a cell phone with a PDA? Then hear the consumer voice of the manufacturers, began to launch a mobile phone and PDA integrated products, from NOKIA 9000, Motorola A6188 (Taiji), to the recent launch of th

According to foreign media reports Investment "The decision made by Karl ikan was split into two. Some analysts expressed regret recently and listed the top ten factors for Motorola's decline. Motorola was founded in September 25, 1928. In the past 80 years, Company It has created many brilliant achievements, including the Radio responder, dynatac, the world's first commercial mobile phone, the world's first GSM digital phone, And Tango.

Recently, a FPGA was added to the PowerPC board, and the PCI-e was debugged when a PCI-E was used to connect the board. Since VxWorks itself has already written the driver, it can be called directly during use, but soon the problem arises: at first, the MMAP method was directly used to map the FPGA bus to the application's memory space and try to read and write. This method is relatively simple and does not need to be copied between the kernel and the

Before learning about the Interrupt Processing Mechanism, let's take a look at the interrupt source of PowerPC. Here we use the e300c3 kernel. From the perspective of the e300 core, the interrupt source can be divided into exceptions and external interruptions, exceptions are generated by the e300 kernel, such as illegal commands or TLB Miss during memory access. This situation is too complicated. If we do not go into the details, the interruptions me

This section describes part of the PowerPC-based second-stage Linux Startup Process. MMU initialization involves a large amount of content and a large amount of code. This section continues to describe the MMU hardware initialization and final MMU enabling process. Before getting started, I first pointed out an error in the previous article. When I introduced the RFI instruction in the mmu_off function, I thought it was an interrupted return, but then

We know that Motorola is working hard to enable its smartphones to quickly upgrade to Android 5.0 Lollipop. Now it looks like the upgrade time is earlier than expected. A few days ago Motorola leaked a beta version of Android 5.0 Lollipop that was only tested by Motorola smartphone Saker users. As a result, Motorola wi

Advantages of PowerPC over arm: With its outstanding performance and high integration and advanced technology, PowerPC chips are used in network communication applications, industrial control applications, home digitalization, network storage, military fields, power System Control is widely used. because PowerPC is cheaper than arm devices Tools are pirated every

Program █ to debug MIDlet When writing the Spotlet on PalmOS, we can use SYSTEM.OUT.PRINTLN () function to help us print some messages to help debug, what about the MIDlet on the phone? In principle, we can still use the SYSTEM.OUT.PRINTLN () function to do some output. When the emulator executes, it prints out some messages on the command line. In addition, on the PalmOS, there are KVMUTIL.PRC that can help us to record the message that the program outputs. What about the phone? Because there i

earnings reports released by the internet search giant, its profit in the third quarter increased by 36.5% to $2.97 billion, and its earnings per share was $8.75. If it is not included in a one-time project, earnings per share for the quarter are $10.74. Revenue increased by 12% to $14.89 billion. The actual revenue of the traffic cost paid to the partner by USD 2.97 billion is USD 11.9 billion. Previously, analysts expected Google's total revenue to be $14.79 billion, with earnings per share

Google's acquisition of Motorola was a bit surprising, but it should be reasonable. After all, Android has become the most shining feature of Google in addition to search. Recently, Android has been under a "patent" disadvantage, and Apple, Microsoft, and other companies seem embarrassed. Google's move is clearly conducive to protecting Android, partners, and the entire ecosystem. The role of Motorola is n
