Processors
============
The Nokia N900 is powered by OMAP 3430 ARM Cortex-A8, which is a
system-on-a-chip made by Texas Instruments based on a 65 nanometer
CMOS process. The OMAP 3430 is composed of three microprocessors; the
Cortex A8 running at 600 MHz (up to 1.15 GHz with correct
overclocking) used to run the OS and applications, the PowerVR SGX530
GPU made by Imagination Technologies which supports OpenGL ES 2.0 and
is capable of up to 14 MPolys/s and a TMS320C64x, the digital signal
processors, running at 430 MHz used to run the image processing
(camera), audio processing (telephony) and data transmission. The
TMS320 C64x main purpose is to offload the Cortex A8 from having to
process audio and video signal. Moreover, the OMAP 3430 on some N900
devices has been successfully over-clocked up to 1150 MHz by using a
modified kernel and editing the kernel power configuration file. The
system has 256 MB of dedicated high performance RAM (Mobile DDR)
paired with access to 768 MB swap space managed by the OS. This
provides a total of 1 GB of virtual memory.
