Signal Integrity Design and Analysis for a 400 MHz RISC Microcontroller

摘要

A high-speed 32-bit RISC microcontroller has been developed. In order to realize high-speed operation with minimum hardware resource, we have developed new design and analysis methods such as a clock distribution, a bus-line layout, and an IR drop analysis. As a result, high-speed operation of 400 MHz has been achieved with power dissipation of 0.96 W at 1.8V.
