The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as Split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.

PCI-PCI 桥启动时，一般需要从EEPROM 预读取配置数据。更改EEPROM中的数据一般需要专用的烧结器，这给调试过程带来不便。尤其是采用表贴封装的EEPROM。本文以Intel 公司的Dec21554PCI-PCI 桥为例，介绍一种在线读写EEPROM 的方法。EEPROM选用的是ATMEL 公司生产的AT93LC66，4Kbit，按512×8bit 组织。
