CoreTile Express

CoreTile Express 板在 Versatile™ Express 开发系统中提供主系统 CPU。CoreTile 必须与提供电源、配置和外设连接的主板 Express uATX 板配对使用。

处理器子板 Express 板与 Versatile 产品系列中的前代产品的不同之处在于，其内存和 LCD 控制器等高带宽外设是与 ARM 处理器一起在测试芯片中实现的。这会显示提升性能，使系统更适合进行软件基准测试并完全能运行 Debian Linux 等桌面操作系统。

处理器子板 Express 系列支持的 ARM 处理器有：

• Cortex™-A15 MPCore
• Cortex-A9 MPCore
• Cortex-A7 MPCore
• Cortex-A5 MPCore
