Short Content:     The embedded system is moves in limited space and in the limited resources, realizes some kind of specific function or the function set installment highly effective. Its development usually receives the detachment condition the limit, such as weak CPU handling ability, the small memory space, few may supply the choice the peripheral device, the limited power source supply and so on. Each embedded system's development is the careful planning all, uses the limited resources to display the biggest ...

Short Content:        First, introduction        Linux itself for time-sharing operation system, its system objective for good average response time and high volume of goods handled, but the real time system main consideration duty on time completes, reduces the advancement movement unpredictability as far as possible and so on. But compares Linux with the commercial embedded operating system to follow GPL, has the source code to open, to have custom-made conveniently, merits and so on support widespread computer hardware, therefore, ...

Short Content: Along with DSP (digital signal processor) the performance improvement, the application scope's expansion, specially day by day increases in the expense class electronic products' application, DSP besides continues to undertake the traditional algorithm processing core role, but also needs to complete some control or the businesslike work, but these work before often is by the control, thread managed capacity stronger MCU or CPU completes. The embedded real-time operating system's application has solved in the DSP system development 2 important problems: ...

Short Content: Abstract: Superelevation frame frequency real-time image's long sequence gathering saves the question which has been difficulty with solves. This article based on the SCSI main line's system info, proposed that one kind of new image data gathering memory system's technical program and the architecture, and design one kind supervelocity, digitized, the embedded system prototype. The test result indicated that in the multichannel simultaneously uses in the situation, gathering and the memory speed has achieved 100Mb/s, satisfied 1000 /s black and ...
