基于ADSP的视频SoC验证方案及其接口的设计

Video SoC verification scheme based on ADSP and the design of its interface

视频SoC规模的飞速增长,给FPGA验证带来了很大的挑战,大容量的外部SDRAM以及更多的外设模块的采用,不但增加了硬件的复杂度,也给相应驱动程序的调试带来了很大的难度。为了全面有效地进行FPGA验证,提出了一种在SoC验证平台中利用ADSP-BF 537作为处理器的验证方案,并重点介绍了ADSP外部M em ory总线和SoC系统总线(AHB)转换模块的设计。该方案已成功运用于视频SoC的验证系统中,既降低了开发成本,又提高了系统验证的效率和功能的完整性。

The fast development of video SoC has brought big challenges to FPGA verification. The utilization of large capacity of external SDRAMs and substantive peripheral modules not only increases the complexity of the hardware, but also causes difficulties in debugging driver programs. To verify the function completely and effectively, an improved scheme of SoC verification platform is presented, in which ADSP-BF537 is used as its processor. The interface module converting ADSP external memory bus to SoC system bus （AHB） is discussed. This scheme has been successfully implemented in video SoC verification system.
