ST EVALSP1340 MPU開發方案

2012-06-26

ST公司的SPEAr1340是SPEAr®(結構處理器增強架構)系列微處理器的系統級芯片(SoC),CPU子系統采用高達600MHz的2x ARM Cortex A9核,每個核有32+32 KB L1高速緩存,共享的512KB L2高速緩存,高達166MHz的片上網絡總線矩陣, 32KB引導ROM,32+4KB靜態RAM,主要用于低成本平板電腦,薄型客戶端,媒體手機和工業/打印機智能屏.本文介紹了SPEAr1340主要特性,架構框圖以及EVALSP1340CPU評估板主要特性,框圖,電路圖,材料清單和PCB布局圖.

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.

In particular, high-performance master agents are directly interconnected with the DDR memory controller in order to reduce access latency. The overall memory bandwidth assigned to each master port can be programmed and optimized through an internal weighted round-robin (WRR) arbitration scheme.
