The intention of this paper is to analyze the overhead of memory used, while employing a C compiler as opposed to Assembly for PICmicro® MCU projects. The example code and the numbers used in this paper are for a 14-bit opcode target processor. ROM location counts are given for 14-bit words. For estimation purposes,...

This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This...

MIPI D-PHY is a practical PHY for typical camera and display applications. It is designed to replace traditional parallel bus based on LVCMOS or LVDS. However, many processors and displays/cameras still use an RGB, CMOS, or MIPI Display Pixel Interface (DPI) as interface. A bridge is often required to connect a processor...
