When I look at the lpc1343 program, there is always a statement like this in while(1). I don't know why, so I have to look for the answer everywhere and record it as follows.NOP, SEV, WFE, WFI and YIE...
I have a question. If I frequently request memory (malloc) under WINCE and call free to release it, can the memory be released as soon as free is called, or does it need to wait until the process exit...
Since I couldn't set up H-JTAG with source code debugging, I don't have its JTAG emulator.But the board can be downloaded and run normally with H-JTAG version 0.91, and I already have the previous wig...
Designers use PSpice primarily to simulate analog circuits. However, it can also be used to simulate digital filters. The main components in a digital filter are delay elements, adders, and multipl...[Details]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
Keeping the heart environment compact and warm is beneficial in most cases, but it’s another story for electronic heart scanners. When GE Healthcare was designing a scanner that was said to be the fas...[Details]

The intelligent detector discussed in this paper is an integrated semiconductor photodetector. Compared with traditional semiconductor photosensitive devices, its most ...[Details]
MIPS Technologies Inc. has introduced the CI10084tg, a next-generation global positioning system (GPS) RF tuner IP solution. The silicon-proven, integrated low-noise RF front end for GPS receivers...[Details]
With the continuous emergence of new technologies and the increasing complexity of DSP real-time systems, there are more and more different types of external devices. Writing drivers for these exte...[Details]
Introduction
Wireless operators are driving demand for broadband and data rates by offering enhanced data services to increase average revenue per user (ARPU). The need to provide users with ...[Details]
Preface
In the application of PLL, DLL and CDR circuits, people generally require the output clock signal to have a 50% duty cycle so that data can be sampled at both the rising and fallin...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
0 Introduction
One of the basic tasks of machine vision is to obtain image information from the camera and calculate the geometric information of objects in three-dimensional space, so as ...[Details]
