2.2 Processor, graphic chip
In the SIMpad SL4, an Intel

, 32-bit RISC processor with a
nominal clock frequency of 206 MHz is used. This processor provides very high
computing power combined with very low power consumption, unlike conventional x86
processors.
To achieve optimum control of the high-resolution SVGA screen with its 16-bit colour
depth (65536 colour levels, “high colour” resolution with photo quality), an additional
graphics chip is used. This makes the screen set-up faster and the computing power
higher because of the reduced load on the processor.
