AMD Geode LX is a family of highly integrated embedded
microprocessors. The Geode GX2 processor includes CPU core, video
processor, display controller, 2D graphics processor, AES
encryption/decryption hardware, random number generator and GeodeLink
interface modules, such as control Processor, Interface units, DDR
SDRAM memory controller and PCI bridge.
Based on Geode GX2, the LX
processors include many enhancements to the CPU core, GeodeLink and
other components. Performance of the CPU core was significantly
improved by increasing the size of level 1 instruction and data
caches from 16 KB to 64 KB, adding 128 KB L2 cache, and increasing
maximum frequency of GeodeLink memory controller and Interface Units.
The CPU features new Video Input Port and Security block, that
includes 128-bit AES hardware support, True Random Number Generator
and optional 2Kbit EEPROM. The Geode LX microprocessors are
manufactured using 0.13 micron technology, and have lower core voltage
and power consumption than the Geode GX CPUs.
Like Geode GX CPUs, the Geode LX microprocessors are marked with
rated speed which is relative to frequency of VIA C3 microprocessors.
