摘　　要：随着集成电路进入SoC(System-on-Chip)时代,IP复用在SoC系统设计、集成过程中不可避免,不同IP核与总线之间的接口差异已经成为IP复用的主要障碍.通过研究各种IP核的总线接口特征,本文设计实现了一种面向AHB总线从单元的可复用接口,通过硬件和软件两个层次的配置,该接口可满足某一具体外设对接口的要求.目前该接口模块已成功应用在三角函数、UART、CAN等外设的集成中.With the integrated circuit going into SoC era, the reusability of IP is inevitable in the process of SoC system design and integration. The Discrepancies between various IPS and bus interface, however, have became the main obstacle for IP reuse. By studying the bus interface characteristics of various IPs, the design of reusable interface for AHB bus slave is designed and implemented in this paper, which can meet the interface requirements of a specific peripheral. The interface module has been successfully applied in the integration of trigonometric functions, UART, CAN etc.
