Samsung's 533MHz A9home CPU successorBy Nick Brown. Published: 11th Aug 2007, 12:25:37 | Permalink | Printable
Nothing like a little speed boost, eh?The recently unveiled Samsung S3C2443 processor is a close cousin to the A9home's CPU - leading to speculation it could be used to upgrade Advantage6's diminutive 400MHz computer.
The ARM-compatible processor builds upon many features found in its older relative, and also introduces a few new ones. These include a 533MHz ARM920T core, support for multiple memory types up to 1 GB in size and USB 2 provided as standard.
Another improvement can be found in the memory bus: it is multilayered with a speed of up to 133MHz to enable simultaneous data transfers between the processor, memory and any peripherals. In terms of graphics support, the manufacturer said: "Its flexible LCD controller enables designers to specify many different displays, such as 4-bit black and white, 12-bit CSTN and 24-bit TFT."
However, it is understood a non-Samsung chipset could be considered for a future A9 machine, according to well placed sources, such as an ARM-compatible processor from Freescale. The S3C2443 has been deployed in a number of handheld gadgets so far this year.
Since the A9home's launch in 2005, some users have raised concerns over the machine's non-upgradable 128MB RAM, lack of USB 2, and slow progress on finishing its version of RISC OS. AdvantageSix have said a number of personal set backs have hit its development team, leading to delays.
