1、ARM第一款采用新安全分区架构的Morello评估板现已交付给研究人员
https://www.arm.com/why-arm/architecture/cpu/morello
https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/
ARM已经推出了一种名为Morello的新型隔间式安全微处理器设计的第一个版本（Morello是ARM领导的一项为期五年的研究计划的一部分），该设计有可能从根本上改变未来处理器的开发和编程方式，以提高内置安全性。
分区化的一个强大功能是，即使一个隔间被攻击者破坏，攻击者也无法突破隔间来访问任何其他信息，或者全面控制计算系统。
2、三星实现基于MRAM的内存计算设备
https://www.tomshardware.com/new ... in-memory-computing
https://www.nature.com/articles/s41586-021-04196-6
MRAM由于其低电阻而无法在此类架构中使用，MRAM对于内存计算具有一些非常有吸引力的特性，即其非易失性，运行速度，耐用性和大规模生产的经济性。
三星研究小组的关键架构创新是测试基于MRAM单元的64×64阵列，"该阵列通过使用电阻求和进行模拟乘法累加运算的架构克服了低电阻问题。
补充：关于MRAM（磁阻式随机存取内存）
一种非易失性内存技术，从1990年代开始发展。这个技术的拥护者认为，这个技术速度接近SRAM，具有快闪存储器的非易失性，容量密度及使用寿命不输DRAM，平均能耗远低于DRAM，成为真正的通用型内存。
相比FRAM铁电，MRAM性能更加强劲，读写速度更快，支持无限次读写，超宽的耐温范围，可实现超过20年的数据记录。
3、Qt6.3 Alpha开始面向商业用户推出新版Qt Quick Compiler编译器
https://www.qt.io/blog/the-new-qt-quick-compiler-is-coming-in-qt
新版Qt Quick Compiler的目是让QML以"接近原生方式的速度"运行，并且随着后续版本的推出，希望启动和运行速度可以提升30%
4、Onera Health推出其首款Onera Biomedical-Lab-on-Chip，用于穿戴健康的超低功耗生物信号传感器处理器

11、H7-TOOL本周进展
H7-TOOL详细介绍：https://www.armbbs.cn/forum.php?mod=viewthread&tid=89934
（1）H7-TOOL的高速DAPLINK或者其它下载器调试低功耗，看门狗之类的工程可以冻结他们，继续调试
这个是芯片专门设计的功能，就是为了方便用户在低功耗模式下载可以继续使用调试。以STM32H7为了，可以在MDK option选项的此处进行设置：
也可以直接调用API设置：

（2）H7-TOOL的LUA小程序教程第4期：I2C总线开发
LUA脚本的好处是用户可以根据自己注册的一批API（当前TOOL已经提供了几百个函数供大家使用），实现各种小程序，不再限制Flash里面已经下载的程序，就跟手机安装APP差不多，所以在H7-TOOL里面被广泛使用，支持在线调试运行，支持离线运行。
TOOL的LUA教程争取做到大家可以无痛调用各种功能函数，不需要学习成本。
