二 概述
nTwo ARM Cortex-M3 processors clocked at 200MHz
nAn attribute MMU (for cache & internal translation) and full MMU for a virtual to physical mapping
•BIOS + SYSLINK + [ APPS ]
•所有的imageimg/video处理都跑在core1上，即appM3上.
•OpenMAX IL1.X是唯一的调用ducati的接口。

三 bios
nSYS/BIOS is a scalable real-time kernel
nIt is designed to be used by applications that require real-time scheduling and synchronization or
realtime instrumentation
realtime instrumentation
nprovides preemptive multi-threading, hardware abstraction, real-time analysis, and configuration tools.
nSYS/BIOS is designed to minimize memory and CPU requirements on the target
nThe threading model provides thread types for a variety of situations.
n Hardware interrupts
n software interrupts,
n tasks
n idle functions
n periodic functions
ncommunication and synchronization between threads, include semaphores, mailboxes, events, gates, and variable-length messaging
An interrupt dispatcher handles low-level context save/restore operations and enables interrupt service routines to be written entirely in C
nReal Time Software Components (RTSC).
nRTSC itself is an open-source project
nRTSC provides critical run-time APIs that SYS/BIOS and its users leverage.
nSYS/BIOS is implemented as a set of RTSC packages, each of which delivers a subset of the product's functionality.
nAn application's configuration for SYS/BIOS Using RTSC: *.cfg (in JavaScript syntax), setting properties and call methods provided by objects
