本文提出了一种数据传输方法,可以实现高速率,而不需要其他方法的超快时钟或超宽总线。其思想是使用通信系统中常见的调制技术在每个时钟周期内通过每个引脚传输多个比特。相位调制实现简单,使用20 MHz时钟时,每个引脚的峰值传输速率为160 Mb/s。该方案可以证明对于印刷电路板(PCB)和多芯片模块(MCM)上的芯片到芯片或系统总线接口都是有效的。&lt;<ETX>&gt;
This paper proposes an approach to data transfer that can potentially achieve high rates without requiring the ultra fast clocks of other approaches, or extra wide buses. The idea is to transfer multiple bits over each pin within each clock cycle using modulation techniques common in communication systems. Phase modulation is simple in implementation and demonstrates 160 Mb/s peak transfer rate per pin using a 20 MHz clock. This scheme may prove effective for chip-to-chip or system bus interface both on printed circuit boards (PCBs) and multi-chip modules (MCMs).<<ETX>>
