DSP performance of the Intel Core i7 microprocessor: the hits just keep on coming
Posted by John Keller
CHANDLER, Ariz. -- Just when embedded computing developers are getting used to the benefits of the Intel Core i7 microprocessor, such as floating-point processing for high-performance digital signal processing (DSP), they have something new to get excited about.
The DSP performance of the Core i7, for some applications, is about to double. This should be welcome news for embedded computer developers for DSP-heavy applications like radar processing, signals intelligence, and electronic warfare.
Better yet, Intel chip designers will not change the dimensions or pin connections of the new Core i7 microprocessors, which means single-board computer designers will be able to integrate these chips without redesigning the boards.
Peter Carlston, platform architect of the Intel Corp. Embedded and Communications Group in Chandler, Ariz., says Intel will offer versions of the Core i7 early next year with vector registers increased from four to eight.
That means the chip's floating point operations will increase from four operations per clock cycle to eight operations -- effectively doubling the chip's floating point performance.
This will have two primary benefits for DSP applications designers Carlston explains. They either can do more work in the same size, weight, and power footprint, or they can do the same work in a smaller footprint.
Imagine what that could mean for new generations of unmanned vehicles and soldier systems.
All this should happen by the first quarter of 2011.

Arms embargo against the only reliable U.S. ally in the Middle East
Posted by John Keller
The administration of Barack Obama is orchestrating an arms embargo of sophisticated military weapons against the only reliable U.S. ally in the Middle East -- Israel.
How much sense does this make at a time when nearby Iran is nearing development of deliverable nuclear weapons and is belligerent as ever? If the U.S. and Israel do not stand united against a nuclear-armed Iran, the entire geopolitical situation in South Asia could slip out of control.
In my darker moments I think this must be what the Obama Administration wants.
So what's the problem between the U.S. and Israel? The Israelis and Palestinian Arabs don't like each other much, and the Obama Administration wants the two sides to get along. Israel wants to build 1,600 housing units in East Jerusalem -- an area that has been part of Israel for 43 years -- and the Obama Administration wants the project stopped because it offends Palestinians.
The Obama Administration can't resist intervening in an internal Israeli matter so much that the president is willing to aid and abet a nuclear-armed adversary nearby to develop into a monster international threat. This doesn't sound to me like Obama has his international priorities straight, but I digress.
So what's this arms embargo? Since taking office, Obama has blocked all major Israeli requests for advanced U.S. weapons, including proposed Israeli procurement of AH-64D Apache attack helicopters, refueling systems, advanced munitions and data on a stealth variant of the F-15E fighter-bomber.
According to a story that ran Thursday in the World Tribune, "All signs indicate that this will continue in 2010," a congressional source familiar with the Israeli military requests said. "This is really an embargo, but nobody talks about it publicly."
The latest development in Obama's arms embargo against Israel happened Thursday. World Tribune reported the Administration ordered the U.S. military to divert a shipment of smart bunker-buster bombs from Israel to a military base in Diego Garcia. They said the shipment of 387 smart munitions had been slated to join pre-positioned U.S. military equipment in Israel Air Force bases.
The Obama Administration can posture with an arms embargo all it wants, but Israel has an interesting history of dealing with arms embargoes. After the 1967 War, the French government launched an arms embargo, which denied the French-build Mirage 5 jet fighter to Israel.
By controversial means, Israel acquired detailed plans for the Mirage 5 and build their own jet fighter based on its design. The result was the Kfir jet fighter, which is Hebrew for lion cub.
My point is that if the Israelis want bunker-busting munitions, they are perfectly capable of developing these big smart bombs on their own. Israel does amazing things when the country feels threatened; they have shown this throughout their short history.
Put a nuclear-capable country within the range of short-range ballistic missiles near their borders, and I think Israel pull another rabbit out of its hat -- and the Obama Administration will have nothing to say about it.
