ST EVALSP1340CPU嵌入600MHz MPU开发方案
ST公司的SPEAr1340是SPEAr®(结构处理器增强架构)系列微处理器的系统级芯片(SoC),CPU子系统采用高达600MHz的2x ARM Cortex A9核,每个核有32+32 KB L1高速缓存,共享的512KB L2高速缓存,高达166MHz的片上网络总线矩阵, 32KB引导ROM,32+4KB静态RAM,主要用于低成本平板电脑,薄型客户端,媒体手机和工业/打印机智能屏.本文介绍了SPEAr1340主要特性,架构框图以及EVALSP1340CPU评估板主要特性,框图,电路图,材料清单和PCB布局图.
The SPEAr1340 device is a system-on-chip belonging to the SPEAr® (Structured Processor Enhanced Architecture) family of embedded microprocessors. The product is suitable for consumer and professional applications where an advanced human machine interface (HMI) combined with high performance are required, such as low-cost tablets, thin clients, media phones and industrial/printer smart panels.
The device is hardware-compliant to the support of both real-time (RTOS) and high-level (HLOS) operating systems, such as Android, Linux and Windows Embedded Compact 7.
The architecture of SPEAr1340 is based on several internal components, communicating through a multilayer interconnection matrix (BUSMATRIX). This switching structure enables different data flows to be carried out concurrently, improving the overall platform efficiency.
