TSMC To Build Advanced Semiconductor Factory In Arizona (yahoo.com) 56

An anonymous reader quotes a report from The Wall Street Journal: Taiwan Semiconductor Manufacturing Co. (TSMC), the world's largest contract manufacturer of silicon chips, is set to announce plans to build an advanced chip factory in Arizona (Warning: source paywalled; alternative source) as U.S. concerns grow about dependence on Asia for the critical technology. The plans come as the Trump administration has sought to jump-start development of new chip factories in the U.S. due to rising fears about the U.S.'s heavy reliance on Taiwan, China and South Korea to produce microelectronics and other key technologies.

TSMC is expected to announce the plans as soon as Friday after making the decision at a board meeting on Tuesday in Taiwan, according to people familiar with the matter. The factory could be producing chips by the end of 2023 at the earliest, they said, adding that both the State and Commerce Departments are involved in the plans. TSMC's new plant would make chips branded as having 5-nanometer transistors, the tiniest, fastest and most power-efficient ones manufactured today, according to a person familiar with the plans. TSMC just started rolling out 5-nanometer chips for customers to test at a factory in Taiwan in recent months. It is unclear how much TSMC has budgeted or if it would get financial incentives from the U.S. to build. A factory capable of making the most advanced chips would almost certainly cost more than $10 billion, according to industry executives.

ARM can definitely beat intel at its own game. Cores introduced now have a comparable FP performance, which is where there is the largest gap at the moment. The Scalable Vector Extensions will leapfrog anything intel will have, with code compiled once and automatically running on machines with 128-bit, 256-bit, 512-bit, 1024-bit or 2048-bit long vectors – and using all the parallelism offered by the system. Integer performance is already on par or better while at the same time using less power. Look up "Fujitsu Fugaku" if you want to see an ARM-based supercomputer. The ISA is more orthogonal and has less baggage, which significantly simplifies decoders – also, ARM chips do not have to use microcode, reducing all the associated problems. So, yes, it is a matter of time, and we are nearly there, but you can expect ARM compatible chips to outperform intel and AMD ones in almost any market. And if you are following recent progress on binary translation and emulation, you should not even have a performance penalty while running code compiled or x86.

Notably absent is stating it's an explicitly right wing idea, which google and the other SJWs redefined it as recently. It's like "1984", people forget that anything else ever existed.

Well, can "suppression of the opposition [...] especially leftist parties" be left wing? It sounds quite right wing. And "retention of private ownership of the means of production under centralized government control" does not look like left wing either. So, yes, fascism IS an explicitly right wing idea. Roberto

The first one is that they are not actually "emulating" the operating system - they emulate the hardware and run Apple's stock iOS on their emulation platform.

Wow. SMH. Emulating the hardware such that you can run the stock software IS emulation in everybody's normal understanding of the word emulation.

I mean, WTF are you even suggesting? That "real" emulation means you have to write your own version of iOS? How would running your own implementation of an iOS-like operating system help you in any way do security testing of iOS itself? Any security bugs you find are going to be bugs in your own implementation, not bugs in iOS.

Good grief. The level of incompetence and insanity among Apple fanbois... What are they making you guys smoke over there in Apple-land?

1) it is different because some articles seem to imply that they "emulate" iOS. They do not. They emulate the HW it runs on. So they are using iOS on an unauthorised device. Whether you think this is good or bad is irrelevant, this is a matter of law. And I am not a lawyer, but clearly you are not one as well.

2) I am not an Apple-fanboy, even though I use Apple products because they (on average) suck, but still less than all alternatives [hint, my former student Halvar Flake used to say the same]. As for "level of incompetence", well, try to figure out who I am and what role I have at my employer.

Apple said in the complaint. "Far from assisting in fixing vulnerabilities, Corellium encourages its users to sell any discovered information on the open market to the highest bidder."

What's wrong with selling your wares on a free and open market with genuine price discovery? I guess Apple thinks it should, for some reason, get first crack at new cracks, even if they're low-balling the compensation amount? While simultaneously making it harder for the people to do this line of development work?

Sounds like communism/socialism/totalitarianism to me. FU APPL.

There are two points here. The first one is that they are not actually "emulating" the operating system - they emulate the hardware and run Apple's stock iOS on their emulation platform. So they use Apple's software on an unauthorised platform. You may not like this but who writes the software has the right to restrict its use. The second point here is that even their behaviour would probably get some protection from the law if they used their emulation tech for academic purposes, or to help the common good. But this is not the case. Hence they are violating Apple's IP rights to get a profit. What apple is doing is not "communism/socialism/totalitarianism". It is capitalism, and in fact a rare case where it is actually good.

Comment Re:SVLTE/SVDO? (Score 1) 47

Well, ok, now I see the connection, but, again, these are two independent things. SVLTE can be implemented today already. It was done already with the MSM8960 and MDM9x15 from 2012, using only one baseband (previous solutions used two) but required additional antennas (IIRC three, and two RF chips).

Now that one person is doing it, everyone is going to have to do it. It's going to be difficult selling a 32-bit processor when the guy across the street is selling a 64-bit one.

There's a lot more reason to go 64 bit than that. The biggest is that it's not going to be long before smartphones and tablets have > 3 GiB RAM. Yeah, there are all sorts of workarounds you can use to access larger amounts of RAM with 32-bit pointers, but it's much nicer to have a flat address space, including plenty of address space for memory-mapped devices. Granted that we're probably a couple of years away from needing 64 bits, but it's coming, fast.

32-bit ARM already addresses more than 32 bits: recent 32 bit ARM architectures have a 48 bit address space, and several chips support 36 or 40 bits. The problem of individual applications addressing at most 32 bits is minor, at this stage, but sooner or later we will have big graphics editing applications on Tablets, and larger address spaces help.

The main advantage that Aarch64 has at this very moment is that it offers a more streamlined instruction set (that makes instructions easier to reorder) and more registers. Even just compiling 32 bit code in the new model you can get impressive performance gains.

So does this finally mean we'll get Simultaneous voice and LTE/SVDO back?

64-bit ARM and support for simultaneous voice and LTE/SVDO are completely different things.

The 64-bit ARM cores are application processors (AP). They do not control the modem (that can be part of the SoC together with the AP or an external component): Qualcomm modems have nifty internally developed (and publicly documented) a VLIW CPU called "Hexagon" that offers DSP-like instructions to control the modem. Some modems have two, and another Hexagon is used to process audio and cal also run user provided applications. You can find some information here http://en.wikipedia.org/wiki/Q... and a lot more is linked.

And even this has nothing to do with dual radios. They are independent things.

Run time optimizations can be (are?) a very bad idea in a kernel, where very often the exact predictability of execution paths makes the difference between a working kernel and a misbehaving one.

Well, with Clang/LLVM you can compile the kernel straight to the target architecture with run time optimization turned off, as well as building what else you want, for instance your applications, with run time optimization turned on. Easy as customizing your Makefiles.
