Of course you can not trust them. Just look at OpenSSL. If you truly need "safety critical" there are no shortcuts.

Which tools are Windows only? I have developed for FPGAs from all major vendors exclusively on Linux. But closed source expensive tools are a problem.

It is not the same thing. 11ac does normal beam forming not network/distributed MIMO.

The receiver can determine the "Direction Of Arrival" of a received signal which it uses for beam forming (this is how it typically done, don't know anything about pCell).

It's different from the MIMO employed in Wifi or "normal" LTE. They do not create a cell per user, neither does a femto cell base station (it only creates a small cell, not a personal cell).

The pCell is "synthesized" using all base stations in range I guess. Which base stations that are involved in your pCell changes as you move around ...

What kind of work do you do? My experience is that ESA lets the industry (and maybe universities) do most of the SW/HW development and ESA does stuff like requirements and high level management. But I have never followed a project from

"In the (somewhat less common) case where other people are also working on the same shared remote feature branch, also rebase changes coming from it" I don't think this use case is uncommon, and unfortunately when you are mul

You can't use a struct in a portable way for sending directly on the network or writing/reading to disk. You must always properly serialize the data despite the fact that the _order_ of the elements is defined.

The elements of a C struct must be sequentially ordered in memory as specified in the code, that's defined in the standard.

A right shift of a signed integer is implementation defined.

You misunderstood me completely. I was not saying one should study CompSci, that was you (even though you said EE was preferable). I was merely saying that for someone wanting to _start_ doing embedded work saying "go get a ___ degree&

I think that was pretty bad advice. If someone wants to start doing embedded you tell them to go get a CompSci degree (i.e. studying algorithms and logic). And disrespecting Arduino like that does not seem good either. Doing Arduino will ac

My take on Quark is that it is Intels synthesizable offering. It is available as an IP core that you will include in your own SoC designs. This board could serve as a prototyping board for your SW team while you're busy finishing your

I don't understand why they don't put an MMU into the R-series. Should't take up much area nor waste any cycles if not enabled (and not necessarily when enabled either).

I remember having lots of fun with C as a teenager. This was in the early 90s. We wrote games and demos using mode 13h (320x200 1 byte/pixel) in DOS (thus pretty much bare metal). Those were the days. I think it was the perfect way to

I bought the TI-85 dispite it being an older model because it had been hacked so I could program it in z80 assembler.

Actually since about 2.6 uCLinux has been merged into the mainline kernel. Several MMU less targets are supported.
