The Geode NX processor implements AMD PowerNow!™
technology, which achieves lower power states by adjusting
the
NX 1500@6W* and NX 1250@6W* use fixed operating
voltages, and are therefore only able to achieve lower
power by adjusting the processor’s frequency, while the
NX 1750@14W* can be adjusted in frequency and voltage
for lower power operation. See Section 5.4.1 "Valid Voltage
and Frequency Combinations" on page 49 for more infor-
mation. The Geode NX processor is available in a low-pro-
file, lidless organic pin grid array (OPGA) package.
The Geode NX processor features seventh-generation
microarchitecture with integrated L2 cache that supports
the growing processor and system bandwidth requirements
of emerging software, graphics, I/O, and memory technolo-
gies. The high-speed execution core in the processor
includes multiple x86 instruction decoders, a dual-ported
128 KB split level-one (L1) cache (made up of a 64 KB L1
instruction cache and a 64 KB L1 data cache), a 256 KB L2
integrated cache, three independent integer pipelines,
three address calculation pipelines, and a fully pipelined,
out-of-order, floating-point engine.
The
3DNow!™ Professional technology, a high-performance
cache architecture, and the 266 MHz, 2.1 GB per second
AMD processor system bus. The AMD processor system
bus is designed to combine the latest technological
advances, such as point-to-point topology, source-synchro-
nous packet-based transfers, and low-voltage signaling, to
provide an extremely powerful, scalable bus available for
any x86 processor. The AMD processor system bus oper-
ates at twice the front side bus (FSB) frequency.
The Geode NX processor is binary-compatible with existing
x86 software and backwards compatible with applications
optimized for enhanced 3DNow!, MMX
tions. Using a data format and single-instruction multiple-
data (SIMD) operations based on the MMX instruction
model, the Geode NX processor can produce as many as
four, 32-bit, single-precision floating-point results per clock
cycle. The implemented 3DNow! Professional technology
includes new integer multimedia instructions and soft-
ware-directed data movement instructions for optimizing
such applications as streaming video for the Internet, as
well as new instructions for digital signal processing (DSP)
and communications applications.
*The AMD Geode™ NX 1750@14W processor operates at 1.4 GHz, the NX 1500@6W processor operates at 1.0 GHz, and the NX 1250@6W processor operates
at 667 MHz. Model numbers reflect performance as described here: http://www.amd.com/connectivitysolutions/geodenxbenchmark.
