After reading Shao Beibei's book > and looking at the overall framework of these books, I have two questions in my mind: 1. The book talks about the porting of μC/OS-II to 80X86, but after porting μC/...
Virtual memory uses disk to expand memory capacity. It is also called "memory-external memory hierarchy". Where is the external memory in Windows Mobile?...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
Instrument stepper motor
The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
