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
