Hardware Specification
Core Processor
The GCM is a low-power single-board computer based on the Marvell PXA320
processor. This 32-bit processor is optimized for power-efficient, graphics-intensive
applications.
The following are the key features of the PXA320:
•
Scalable general-purpose processing up to 624 MHz
•
32 kB instruction and 32 kB data L1 cache, 256 kB L2 cache
•
Marvell Scalable Power Manager technology
•
Multimedia acceleration with Intel® Wireless MMX™ 2 technology
•
768 kB frame buffer
•
Integrated support for industry-standard interfaces and wireless technologies
•
Quick Capture interface supporting camera sensors up to 3 megapixels
PXA320 GPIO Cross-Reference
The PXA320 general-purpose input and output lines (GPIO
n
) control various discrete I/O
on the GCM such as interrupts, enables, and controls. The following table lists the
signals that are specific to the GCM.
