Originally I was using the 7" touch screen sold from Sparkfun. That works but the software I am trying to use wants a slightly higher resolution. Also, the touch screen is less than optimal for software that is not designed for touch screens. Not a fault of the Pi or touch screen. The elements that allow you to interact with the software are too small to touch with either a finger or stylus. Anyway, I tried buying a couple of HDMI screens. One came from Amazon and was pretty much junk on arrival, the built in speaker had come loose in shipping. That screen worked for a few minutes before it quit working. Wouldn't even work with my laptop. The next screen I bought is a 7" 1024 x 600 unit from Adafruit. This display seemed to be perfect, uses about 500mA according to the specs which would be great for running off battery power. Anyway, I cannot get the Pi to display anything on it. The display works, if I connect it to my laptop it works fine. The green LED lights, according to the display's documentation this means it has a valid HDMI signal. I tried adding the following lines to config.txt:
<CODE><h1>uncomment if hdmi display is not detected and composite is being output</h1><p>hdmi_force_hotplug=1</p><h1>uncomment to force a specific HDMI mode (here we are forcing 800x480!)</h1><p>hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=1024 600 60 3 0 0 0
</CODE></p><p>which didn't help.</p><p>I am using a fresh install of Ubuntu Mate, 16.04. Anyone have any suggestions?</p></p>

Ethernet hasn't been upgraded to gigabit, and there's no USB3 either..
I guess that's going to come out in Pi 4.</p></p>

It runs fldigi and gnuradio well and is simple to setup with the 7" touchscreen and Raspian Linux. 2 things to note, bluetooth setup may be a bit convoluted, and so far I have found it impossible to get the wireless to connect to a hidden network. It works well connecting to wireless networks that broadcast their ssid. I had found instructions on how to connect to a hidden network but they didn't work and I didn't have time to troubleshoot further. I am very surprised at the computing power of such inexpensive little board. Do yourself a favor: Be sure you have a power source capable of 5V and maybe 2A. My 1.5A cell phone charger is barely enough to boot it up. I have found that I sometimes need to have all USB peripherals unplugged, and plug them in one at a time after bootup. Also, buy a stylus. Your finger tips are probably much too big to operate most software programs running on a 7" screen ;). With the bluetooth setup you may find that blueman does't work, in which case you may have better luck with a command line tool. I ended up having to uninstall blueman as it was interfering with the command line utility.</p>

Using registers is similar to just grabbing a PB&J sandwich off the counter. Cache is similar to grabbing bread, PB and Jelly from your pantry and making a sandwich. RAM is like going to the store to buy ingredients. Registers are definitely quicker, but RAM isn't unreasonable. Oh, and going to the disk is like planting your own wheat, peanuts and strawberries!</p>

This is a point of CPU architecture that can be a little bit hard to understand.</p><p>First off, the registers:
A computer has different levels of storage. Usually we think of the RAM as the "fast" storage and the disk (or SD card, etc.) as the "slow", persistent storage. We load things from disk into RAM and often keep them there for a while, because it would slow things down if we had to keep storing to and retrieving from disk. (and when we run out of RAM, the OS starts swapping things to disk - which absolutely murders performance)</p><p>The trick is, there are deeper layers that follow the same pattern. CPU cache is faster than the main RAM, and CPU registers are faster than the CPU cache. At this deepest level, you can think of the CPU registers as the set of data the CPU can work with very quickly, and the main RAM as the slower, longer-term data storage. (We don't tend to think of RAM as being slow, but when you're running some performance-intensive code, the difference is speed when you finally have to work with RAM is like hitting a brick wall) In this case, the new processor has (I think) more than twice as many registers, and they're twice the size of those on the Pi 2. (31 general-purpose 64-bit registers vs. 13 general-purpose 32-bit registers)</p><p>There's also a separate set of registers used for floating-point math and SIMD operations, where a larger register is packed with smaller operands that are used together in some calculation: On the Pi 2 (Cortex-A7) there were (I believe) 16 64-bit floating point registers, and on the Pi 3 (Cortex-A53) there are 32 128-bit floating point registers.</p><p>All this means that the amount of data the CPU can work with before it has to go fetch something from RAM is increased. But there's a catch: Your programs have to be compiled in a way that takes advantage of the extra registers. Code compiled to use the full set of ARMv8 registers won't run on ARMv7. It'll just crash. And code that's written to use just the ARMv7 (or v6) registers won't be able to take advantage of the register set on the A53. We went through this with the PI 2 as well, actually: Raspbian (and most Pi-specific distros, I think) was compiled for the original Pi (ARMv6), and due to the bootloader trickery that's required on the Pi, it's not always easy to substitute another distribution. It's kind of unfortunate, but taking advantage of the Pi 3's CPU enhancements isn't going to be easy.</p><p>The Pi 3 will still be faster than the Pi 2, but we won't really tap its full potential unless the software we run (including the OS, probably) is compiled specifically for ARMv8.</p></p>

We buy them from the supplier at $35, pay to ship them here, pay our guys to receive them, stock them, box them up and on many orders pay for free shipping. Truth is that $5 helps cover some of that, if we didn't add it we might not be able to carry the Raspberry Pi for you guys.</p>

Hence on a 32-bit machine with 4GB of RAM a single process might only be able to address 2GB of that, because the other 2GB are set aside as the OS's address space.
Of course, other advantages of a 64-bit CPU apply even if addressing isn't an issue. It'll do 64-bit math faster, because the operands will each fit in a register and the operation can be expressed as a single instruction. And a huge advantage of x86-64 over regular x86, for example, is that the CPU registers aren't just bigger, there's actually more of them. This means compilers can optimize the code much more effectively, reducing the need to repeatedly fetch values from RAM which is crazy-slow. (I dont know if 64-bit ARM offers similar advantages.)</p>
