Balance: The Economics of Great Powers from Ancient Rome to Modern America, Authors: Glenn Hubbard and Tim Kane.
By Glenn Hubbard and Tim Kane – Hard power. Soft power. Smart Power. Superpower. This is the language of foreign affairs, full of meaning but empty of measurement. Vagueness is, of course, purposeful in the hands of skilled diplomats and politicians, but it can signal shallowness, ignorance or worse. Lacking clear metrics for power, the U.S. national security establishment speculates about possible rivals while being led astray by trendy catchphrases.
The United States itself has a larger GDP and higher productivity than 10 years ago, but its long-term growth rate has slowed by half. That’s a reflection of internal imbalance – budget deficits, heavy taxes that hinder incentives to work and innovate, unfunded entitlements and more.
Existential threats hide in plain sight. If the United States wants to be a superpower for another century, it needs to focus on the barriers to economic growth within — not phantoms abroad. more> http://tinyurl.com/q8yjmvl

By Ann Steffora Mutschler – Chip interconnect protocol requirements are evolving as designs move to 20nm and below process geometries, and not always in predictable ways.
The basic concept behind cache is that data is stored closer to processor for faster access. Cache coherence allows copies of that data to be stored in multiple places. But to be coherent, it also has to be updated regularly at all places where it is stored, and that means the interconnects have to keep up with this whole process.
“So suddenly, instead of just talking to memory you’re talking to local memories, and those local memories are talking to other people’s local memories to try and make sure whenever you need something you’ve got the right version,” Drew Wingard, CTO at Sonics said. “That has a big impact on what happens at the interconnect fabric level on these chips.” more> http://tinyurl.com/cf5xgsj

By Graham Bell – Continued increases in SOC integration and the interaction of blocks in various states of power management are exacerbating the X problem. In simulation, the X value is assigned to all memory elements by default. While hardware resets can be used to initialize registers to known values, resetting every flop or latch is not practical because of routing overhead. For synchronous resets, synthesis tools typically club these with data-path signals, thereby losing the distinction between X-free logic and X-prone logic. This in turn causes unwarranted X-propagation during the reset simulation phase.
Lisa Piper, from Real Intent, presented a solution to the X-propagation problem that is part technology and part methodology. more> http://tinyurl.com/d77nhcg
