versatile express cortex-金沙js1005线路

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

the versatile™ express family development boards provide an
excellent environment for prototyping the next generation
system-on-chip designs. through a range of plug-in options,
hardware and software applications can be developed and
debugged.
the coretile express for the arm® cortex™-a15 mpcore™
and cortex-a7 processors is a test chip-based development
platform which implements a complete soc design around these
processors. this chip is the first commercially available silicon
that demonstrates the power-saving capabilities of arm big.
little™ processing it enables:
• exploration of the big.little architecture
• boot code, hypervisor, cluster-switching, device driver and
application software development
• software debug and development of software tools through
the on-chip coresight™ debug and trace infrastructure.
