VIA Luke CoreFusion is a highly integrated microprocessor that
incorporates Eden-N CPU core and VIA CN400 North Bridge. The CPU core
has 64 KB instruction and data level 1 caches, 64 KB exclusive level
2 cache, full-speed Floating Point Unit, enhanced branch prediction,
MMX, 3DNow! and SSE instructions, AES encryption/encryption and
hardware-based random number generation. The CPU runs at 133 MHz
Front Side Bus frequency.
The CN400 north bridge chipset includes FastStream64 memory
controller that supports up to 4 GB of DDR400 memory. The chipset
also integrates VIA UniChrome Pro 2D/3D graphics controller, that has
such features as 8x AGP bus, MPEG-2 and MPEG-4 decoding, dual-monitor
support, DVI flat panel interface, video capture, and full HDTV
support. To interface with a south bridge, the chipset uses 8x 66 MHz
Ultra V-Link interconnect. The Luke CoreFusion processors can be used
with VT8235M, VIA VT8237R Plus or VT8251 south bridge chipsets.
Luke CoreFusion is somewhat similar to Luke-Lite CoreFusion CPU.
The major difference between them is the type of integrated chipset.
The Luke has the following features that are not present in the
Luke-Lite:
- Support for DDR400 memory.
- Video Input Port.
- HDTV support.
- TV-out interface
- MPEG4 decoding.
