Engineers with experience from developing application software based on hardware with an ARM9 processor may have noticed the limitations in performance, memory and otherwise compared with X86 processors. It has been part of the challenge to keep the component cost down.
TI Sitara Cortex A8 and DDR3 memory introduce possibilities for more performance and memory space without price increase. There are Sitara Cortex A8 processors priced in the same category as ARM9 and DDR3 is about half the price compared to DDR2. It makes room for a bigger operating system and more functionality in the application software.
Hectronic believes strongly that TI Sitara Cortex A8 will win a great percentage of the ARM9 business in application areas like for example Fleet Management, Home/Building Automation and Industrial Automation. Typical requirements for these applications include industrial temperature operation, protection against shock, vibration, damp and dust.
TI Sitara isn’t suitable for graphics intense applications but rather applications that require only basic man-machine interfaces often limited to include only buttons, lamps and LEDs. There are a lot of applications in the above mentioned areas that require such rudimentary HMIs only. Power consumption is thereby kept low since increased graphics performance is one of the main power consumers in the typical embedded application.
