This page shall be a container for various pieces of information about Bticion's F454. Most of the information is - for now - derived from just poking around on the device with SSH. So, due to this and in general: of course certain details can be unsure or not accurate, because something has been overlooked.
The F454 is a typical embedded system using a SoC and running a Linux-based system.
The SoC does include, among many peripherals, an ARM processor:
- family: ARM9E
- architecture: ARMv5TEJ
- core: ARM926EJ-S
Apparently DM365 SoCs can run with 216 MHz, 270 MHz or 300 MHz. As of this writing it is unclear what the F454 actually uses.
A look at Linux' /proc/cpuinfo
root@basi:~# cat /proc/cpuinfo Processor : ARM926EJ-S rev 5 (v5l) BogoMIPS : 134.34 Features : swp half thumb fastmult edsp java CPU implementer : 0x41 CPU architecture: 5TEJ CPU variant : 0x0 CPU part : 0x926 CPU revision : 5 Hardware : BTicino BASI board Revision : 0000 Serial : 0000000000000000
TODO: Couldn't we derive the clock speed from the BogoMIPS - at least roughly?
The DaVinci DM365 SoC includes a 720p H264 encoder and decoder - next other co-processors and seems to belong to the group of full-featured DaVinci SoCs of it's time (2008/2009).
Question: Why DM365 - why does the F454 need this 720p en/decoding capability. Wouldn't a DM355 also do it? Related to video entry systems?
