VIA's New Nehemiah M10000 Processor Reviewed 265
Joseph Wharton writes "Mini-ITX.com has a review of VIA's new Nehemiah M10000 EPIA-M motherboard and processor. Some of the new features include a full-speed floating-point unit (finally!), SSE instructions, 64KB of full-speed L2 cache, and (get this) a hardware-based random number generator. Also, there's IO/APIC support in these new procs, potentially paving the way for dual EPIA boards."

This book continues the history of the children of the captivity, the Jews lately returned out of Babylon.

Twelve years he was the tirshatha, or governor of Judea, under the same Artaxerxes that gave Ezra his commission. This book relates his concern for Jerusalem and commission to go thither, chap. 1, 2. His building the wall of Jerusalem, notwithstanding much opposition, chap. 3, 4. His redressing the grievances of the people, chap. 5. His finishing the wall, chap. 6. The account he took of the people, chap. 7. His calling the people to read the law, fast and pray, and renew their covenant, chap. 8 - 10. He peoples Jerusalem and settles the tribe of Levi, chap. 11, 12. He reforms divers abuses, chap. 13. This was the last historical book that was written, as Malachi, the last prophetical book of the old testament.

"Nehemiah is the next generation C3 CPU, and features a number of improvements over the Ezra-T C3 used in all previous EPIAs. It has The 20.5 million transistors, and uses a 0.13 micron process. For comparison, a Barton Athlon or Northwood Pentium 4 have about 55 million transistors, and recent GPUs have over 100 million transistors.
The Nehemiah is designed to work at clock speeds of 1GHz and beyond - the Ezra-T is designed at up to about 1GHz.
Nehemiah has a die size of 52mm2 - the world's smallest x86 processor. It has been designed to minimize power consumption and optimise heat dissipation - VIA call this "Coolstream". Some active cooling is still required, but not very much. Let's hope for a Nehemiah Eden C3 version.
The Nehemiah features SSE instructions instead of the 3DNow! instructions featured on previous C3s. This should bring enhanced performance in 3D applications, which are optimised for more modern SIMD instruction sets. SSE optimised image processing applications should also benefit.
Full Speed FPU - the Nehemiah has a full speed floating point unit for the first time. The Ezra-T has a half-speed FPU. Floating point calculations are used heavily in 3D rendering, multimedia, and streaming applications.
Enhanced 64KB Full-Speed Exclusive L2 cache with 16-way associativity. An exclusive L2 cache gives a larger effective total cache size as it doesn't replicate the contents of the L1 cache. The more cache available, the more chance there is that program loops can run in cache and not comparatively slow main memory.
StepAhead Advanced Branch Prediction - Looks ahead and gathers the data needed to optimally run applications
A hardware based random number generator (RNG) has been added. This creates true random numbers from the random electrical noise on the chip. This is of much use in security applications, allowing a strong cryptographic key to be generated. VIA call this the "PadLock Data Encryption Engine".
Future Nehemiahs will feature IO/APIC support. An Advanced Programmable Interrupt Controller (APIC) provides multi-processor interrupt management - dual processor EPIA anyone?
The Nehemiah is available in EBGA or Socket 370 packages - both are low profile and require less board real estate."

Three years go when VIA merged the Cyrix product name with the Winchip line, they touted the WinChip's lack of Out-Of-Order-Execution and use of Static Branch Prediciton as "features".
This was puported to save power and make the die smaller. Funny to see them do a complete 360 only 3 years later, after their castrated chip has failed to attract a single Tier 1 vendor.
The Cyrix MII sold better than the WinChip / VIA C3; at least Compaq and Emachines were selling systems based on it back in the day. It sold where the WinChip couldn't, because it actually delivered on being both reasonably powerful and dirt-cheap. The WinChip could claim to be dirt-cheap, but reasonably powerful...welll...
So, after so long a wait, do we finally have a winner? A low power chip that can actually play a Divx movie? Perhaps they could get rid of that hardware DVD decoder too, a feature other systems havn't needed since the Celeron 400 / K6-2 450.

The way good OS's generate random numbers is by accumulating a pool of entropy. They typically use a wide variety of inputs and mix them together. That way, if an attacker is able to observe or predict some of the inputs, there's still some more than they can't break. Unfortunately most computers only have expernal sources of randomness; things like ethernet packet timing or keyboard/mouse movement. These things are relatively easy to observe and/or tamper with. (As an aside, does anyone know if any OS uses things like processor temperature/fan speed as entropy inputs?) The on-chip RNG is may not be a really excellent source of randomness, but it's very hard for an outside observer to monitor. (And, it's quite possible that it really is an excellent source of randomness.) Even if it is weak, it's another addition to the entropy pool, and thus strictly good.

Actually, the analysis [cryptography.com] I've seen suggests that the HW RNG is very good. It can generate RNGs at 30-50 Mb/s, with an estimated 0.78-0.99 bits of entropy per output bit. With a built in "whitener", it can generate 4-9 Mb/s with an estimated 0.99+ bits of entropy per bit. If you use it as an entropy pool to feed a strong PRNG, which is the recommended mode of use, it should be a very effective source of cryptographically useful randomness.
Actually, HW random numbers are quite safe. (Score:2)
Testing goes something like
1) Get fscking big sample
2) Run staistical analysis, typically frequency analysis. If no patterns show up (e.g. 60Hz from power supply) you're home free. No fancy algorithm analysis needed, not much to exploit really.
Also, in a worst case scenario you can fall back to software. Though I suppose that a DRM system could get compromised if the "random" data aren't random though.

The Nehemiah M10000 is a very welcome speedbump to previous EPIA Ms. The full speed FPU and SSE instructions give it that extra boost needed to playback any media type we could find - without optimisations or quality tradeoffs.
Although we have benchmarked the Nehemiah as fully as possible (and gained some useful comparisons with earlier EPIAs), it must be remembered that this is not everything that the EPIA is about. In use, all the EPIAs are nippier than their benchmarks would suggest, due to their supporting chipsets. EPIA Ms (of which the Nehemiah M10000 is of course the current ruler) are powerful multimedia playback machines. An EPIA M in a low profile case looks great next to a TV, where a regular PC or even Cube SFFPC will look out of place, overpowered and overpriced for the task. Add a PVR card and you have a perfect HTPC.
As an inexpensive upgrade path for ageing x86 machines, EPIAs are ideal - schools, libraries and internet cafes can benefit from low noise and low power consumption machines. Under Linux, even the EPIA 5000 can perform tasks such as file serving with ease all at the cost of a SCSI card. EPIAs have accidentally gained a following in the modding community (witness the many projects on this site). Although such mods probably represent a small proportion of sales, they show the versatility that this form factor has, and the enthusiasm of its owners. No other manufacturer offers a range of mainstream low noise motherboards at this size and price with these facilities. Other manufacturers will be watching with interest.
