AMD Geode [email protected] Processor Is First to Show EnergyBench Certified Scores for Digital Imaging Workloads
EL DORADO HILLS, Calif.Aug. 7, 2006The Embedded Microprocessor Benchmark Consortium (EEMBC) today announced publication of the first certified embedded processor benchmark scores using EnergyBench, a new standard that provides data on the amount of energy a processor consumes while running EEMBC’s performance benchmarks.
The device benchmarked for these landmark scores is the 500-MHz AMD Geode [email protected]* processor, which was tested in an out-of-the-box environment simultaneously with EnergyBench and ConsumerBench Version 1.1, an EEMBC benchmark suite that allows users to approximate the performance of processors in digital still cameras, printers, and other embedded systems that handle digital imaging tasks.
Across the ConsumerBench battery of tests, performance results for the AMD Geode [email protected] processor ranged from 18 iterations per second for JPEG compression to 204 iterations per second for RGB-to-CMYK conversion, while the EnergyBench scores for each of the kernels indicated an average power consumption range of 2.34 W (for RGB-to-YIQ conversion) to 2.58 W (for JPEG decompression). Overall, the results show that the power consumed by the processor depended on what workload the processor was handling and that this could vary within the ConsumerBench tests by as much as 10 percent.
«As a metric, EnergyBench will be most useful when we are able to compare results from multiple processors side by side, but these results for the AMD Geode LX processor are sufficient to demonstrate the rationale behind EnergyBench — namely that there is no such thing as ‘typical’ power consumption,» said Markus Levy, EEMBC president. «This fact won’t come as news to veteran systems designers, but now they’ll have a tool that will help them avoid any surprises about the power consumption behavior of embedded processors in situ.
«
The AMD Geode [email protected] processor is specifically designed to provide a high level of performance with low power consumption. Typical applications include small form-factor products such as thin clients, interactive set-top boxes, single-board computers (SBCs), personal access devices (PADs), and mobile Internet and entertainment devices.
«It is fitting that the AMD Geode [email protected] processor should be the first embedded processor to be tested with EnergyBench, since this processor family was designed from the ground up to enable both high performance and low power consumption,» said Erik Salo, director of AMD’s Embedded Computing Solutions division. «The EEMBC ConsumerBench and EnergyBench scores clearly demonstrate the excellent performance per watt offered by AMD Geode LX processors.»
EEMBC has implemented EnergyBench using the LabVIEW platform and a data acquisition (DAQ) card, both from National Instruments. While the performance benchmarks are running on the target board, EnergyBench calculates the average energy per iteration using multiple unaliased sampling frequencies and an adaptive statistical process.
The DAQ card samples the voltage levels as well as a trigger channel and writes the samples to a file. The result of the EnergyBench test is the average energy for one iteration of the workload represented by the performance benchmark kernel running on the target. Users can also use the EEMBC setup to examine minimum and maximum power while the benchmark is running.
A detailed ConsumerBench score report for the AMD Geode [email protected] processor, which has been verified and certified by the EEMBC Technology Center, is available for free from the EEMBC Web site at www.eembc.org.
EnergyBench is available for license in conjunction with any EEMBC performance benchmark suite. For further information, visit www.eembc.org.

Introduction
Whilst the end of life (EOL) date for the AMD LX800 has again recently been pushed back, the time will approach when the end of life will be announced, though worryingly to embedded hardware manufacturers, few equivalent alternatives exist.
Intel would push their latest Atom range as a migration path, though whilst you’ll benefit from substantial performance increase, the OEM must also suffer a vast increase in overall power consumption. AMD’s latest offering, the G-Series, whilst an exceptional CPU with lightning graphical performance, still represents a significant increase in required power.
The reality is that more often than not the AMD LX800’s performance is ample for single usage embedded applications. When the LX800’s end of life does arrive, a large gap will be left in the hardware market, for OEMs wishing to continue benefiting from the advantages of x86 products.
Plugging that gap, the new VDX2 CPU from DMP/ICOP Technology addresses this issue.
With a scalable core, at 800MHz (maximum 1GHz) the VDX2 outperforms the LX800 in every area whilst keeping the power footprint to a minimum. The VDX2 actually integrates 5 additional functions into the CPU, so whilst the CPU isn’t directly comparable, the focusing purely on the vCore TDP for comparative purposes – the LX800’s is 3.6W to the VDX2’s 3.45W.
Actually, as the VDX2 is a true System-On-Chip, even integrating graphics and Ethernet, the power savings are even more substantial, due to the negation of external components to satisfy both functions.
The below benchmarks demonstrate the VDX2’s prowess – though don’t take our word for it, DSL are happy to provide evaluation kits for any LX800 migration candidates to test themselves!
