Intel Atom 或 ARM 用于繁重的信号处理工作负载
我想知道哪个是更好的(性能)选项:
- 要获得基于 Intel 双核原子的主板
- 要获得基于 Arm Cortex A9 的主板(pandaboard 等)
我想运行一些轻型版本的 linux 并做一些非常CPU密集型 图像/视频处理(稍后可能是 3D)等计算以及音频处理 在他们身上。当然都是浮点数学。
I would like to know which is a better (in performance) option :
- To get a Intel Dual core atom based board
- To get a Arm cortex A9 based board (pandaboard etc)
I would like to run some light version of linux and do some very cpu intensive
computations like Image/Video processing (maybe 3D later) and also process audio
on them. Of-course all floating point mathematics.

绝对是#2,Pandaboard 是一个 OMAP4 平台。
OMAP4 不仅包含 ARM Cortex A9(它本身不太可能与双核 Atom 竞争),而且至关重要的是,它还包含完整的 C674x DSP 内核,包括浮点和定点数学。
OMAP4 中的嵌入式 DSP 内核完全能够处理 1080p H.264 解码,并有一些空闲资源。我还没有看到有能力做到这一点的 Atom 平台。
(无耻的插件 - 我的公司正在使用 OMAP3 并针对我们的一些利基市场评估 OMAP4,我们可能也有兴趣为您提供帮助)
Definitely #2, Pandaboard is an OMAP4 platform.
OMAP4 contains not only the ARM Cortex A9 (which is not likely to compete on it's own with dual core Atom), but, and this is crucial, a full C674x DSP core, both floating and fixed point mathematics.
The embedded DSP core in OMAP4 is fully capable of handling 1080p H.264 decode, with some resources to spare. I'm yet to see an Atom platform capable of that.
(shameless plug - my company is using OMAP3 and evaluating OMAP4 for some of our niche markets, and we might be interested in assisting in yours as well)
