Hello,
Consider following scenario:
Hi,
We found the following document on Cortex-A9 performance.
List of ARM microarchitectures - Wikipedia, the free encyclopedia
Which claims 2.5 DMIPS/MHz per core for Cortex-A9 2GHz@2 core. However, our Dhrystone result on Cortex-A9 1.2GHz@2 core only showed…
I am trying to enable SMP functionality for our custom target having a dual core.
Below is my understanding w.r.t Basic ARM secondary CPU boot address:
a. The secondary CPU is provided with some registers (named like BOOTUP REG) to keep the…
I am doing some benchmarking and I need to clear the cache before each test. I have this example here:
Caches and Self-Modifying Code
However, I just want to clean the whole cache. Is there an easy way to do that? I do not need to know the start and end…
This is a monthly series featuring embedded developers of the ARM Connected Community.

我们生活在一个移动设备的世界。在这个世界里人们希望互联无处不在,且无所不包。 ARM从这个移动世界诞生开始就一直为它提供相应的解决方案,以此为数十亿的人铺就了一条通向他们移动生活的康庄大道。使得您今天使用的主要计算设备已经不再是那些又难看又费电的傻大黑粗玩意儿…
We live in a mobile world – A world where people connect from wherever they are and whenever they want to everything that matters in their lives. ARM has been part of this mobile world since its beginnings, and provided solutions that…
The ARM Cortex-A mobile application processor product line spans several generations and three main product tiers. Developers and SoC designers experienced with one or more of the newer ARM ARM Processors benefit from an…
Just over 6 years ago, in October 2007, ARM introduced a product that had the potential to change the world. Not just in one market (like mobile), but nearly all known semiconductor markets – Looking back, we can now safely say this product did change…
A question that I am asked many times is – what is the fundamental difference between the high efficiency, mid range and the high performance application processors in the ARM Cortex family?
The simple answer to this is – the power budget…
3月30日上午, 创维在北京瑞创艺术中心举办了Android智能3D电视发布会, 本人有幸被邀请参加了此次活动. 在中国, 举办新品发布会应该说并不鲜见, 但此次发布的Android智能电视新品却有着些许不寻常的意义: 预计是国内第一款上市销售的Android电视; 全球首款采用ARM Cortex-A9 和Mali 400图形处理器的量产电视; 众多全新应用将彻底改变消费者对电视的传统理解.
会场的布置非常讲究, 蓝色的背景和灯光设计使现场充满了魔幻和科技感, Android机器人和动画标志随处可见…
In part 1 of this blog, I outlined the thought process behind the Elba program. Here I'll look at the implementation decisions for the project.
In ARM there are various stages of maturity of a new processor development, reaching silicon implementation…
In the spirit of some of the more well-known ARM-based development boards and their popular communities, I was curious what other innovative ideas are out there being crowdsourced. Just a bit of research quickly revealed eight ARM-based embedded projects…
ARM系统的软件开发周期可因等待昂贵的开发硬件而延迟。要在当今的市场中保持竞争力,需要加快在完全验证的系统上开发全功能软件的速度。快速模型就是为这个目的而生。它提供高性能,丰富,准确的程序员视角(Programmer's View)模型库,支持最新的ARM IP。基于模型库构建的虚拟平台模型可使软件开发流程在硬件原型面世数月之前就启动,极大的缩短整个系统的开发时间。
