ARMv7 and below is bit. ARMv8 introduces the bit instruction set. On a bit processor, you'd see a string starting with armv8 or above if the uname process itself is a bit process, or aarch64 if it's a bit process.
Comparison of ARMv7-A cores
As richard points out, armv7 variants are all bit, so there is no redundant label armvetc. On a linux system, you can easily, although not truly definitively, check by examining a common executable:. If for some reason you need an automated check, creating a table mapped to the "model name" field seems like one potentially sound method other fields, including "model", "cpu family", etc.

ARMv8-A architecture, announced in October , adds support for a bit address space and bit arithmetic.
I don't have access to an ARM machine but what is the output of uname -a and gcc -v? Those might be helpful. It adds a bit architecture, named "AArch64", and a new "A64" instruction set. Arm was the last of the 32bit cpu to go 64bit excluding those that died.Starting with the release of Android Lollipop, the process of installing the Xposed Framework got a bit more complicated. Not only are there separate installers for each Android versionbut now, you also need to know exactly what type of processor is in your device to make sure you're downloading the right files.
In fact, CPU architecture is becoming a factor in more and more scenarios these days, including certain sideloaded app updates and, of course, custom ROMs. There are three main CPU architectures used in today's Android phones. ARM is perhaps the most common, as it's optimized for battery consumption. ARM64 is an evolution of the original ARM architecture that supports bit processing for more powerful computing, and it's quickly becoming the standard in newer devices.
Then there's x86which is a bit more powerful than either type of ARM CPUs, but not quite as battery-friendly, so it's the least common of the three. But regardless of all that, if you're not exactly sure what type of processor you have, I'll show you how to see if it's an ARMARM64or x86 chip below.
The easiest way to find your CPU type is to install an app that gives you a readout about your device's hardware. To begin, search the app by name and get it installed, or head directly to the install page at the following link. Next up, simply open Droid Hardware Info and head to the System tab. Jot this information down and use the table in Step 3 below to find the common name for your CPU type.
List of devices: ARMv7, ARMv6, ARMv5
The information provided in the CPU Architecture and Instruction Sets fields differs a bit from the requirements you'll see for an app or the Xposed Installer, for instance.
So to wrap things up, match up the information you found in Droid Hardware Info with the list below to find the common name for your device's CPU type:. Let us know in the comment section below.

Please I have tried everything to see if it's works for me; but to no avail. My processor is AArch64 rev3 aarch Instructions set armv8a.This is a table comparing microarchitectures which implement the ARMv7-A A means Application  instruction set architecture and mandatory or optional extensions of it, the last AArch From Wikipedia, the free encyclopedia.

CPUs which run at the same hardware frequency: 0 1 2 3 Max: 1. This situation may be fixable, my first impression was no, but looking more closely I see where the speed is coming from.
I will need: inxi -xx 14 which will upload the required debugger dataset. I'm looking back through issue history and in fact, issue 57 specifically states that the fix I did there would not work for multicore ARM cpus, heh. So thanks for being the one to bring the multicore arm cpu speed issue up. By the way, that looks like a very cool piece of hardware, let's see if we can't get better inxi results there. Let me confirm that it worked, because xiin was removed due to a bug that could not be fixed easily in the python used.
I should however ban you and delete this issue because you're tempting me to check into yet more cool micro hardware ;and that's the last thing I need, lol. I just made a really nice apu2 box, but that's not an ARM, it's an AMD system on a chip type board, but standard amd64 architecture.
It is hard to stop buying them because they stack up and are fanless and fast. The MC-1 is new. It is a cluster of four without the SATA storage. I have a pile of HC-1s. So the rough raw error of showing the wrong speed can I think be fixed, but I am not sure if the per core issue can be handled, I'll look more at the data to see if I can find anything.
I'll probably patch the incorrect speed readout first, then look into the per core stuff. I had to reread your original full post, very thorough by the way, I didn't fully understand it the first few times, that often happens when I'm simply not familiar with the concepts, in this case, 1 set of cores having one speed, and the other the other.
If you have any other multi core arm devices that you could provide datasets from, that would help a lot too, along with citing their real specs if you know them. Thanks for taking a look at it. I figured it would take some restructuring of the CPU code since the speed can be different per set of cores. Not symmetrical like most CPUs. I don't have any different types to try. I have another question though that can move to a different thread if it is too off-topic.
It shows up in a lot of places in the debug collected. I was amazed they crammed a GPU in it. Good enough to run OpenCL.Countdown Madness T Products OnePlus One. Oneplus one has armv7 processor rev 1 v7l Not Snapdragon Jul 23, Thread Status: Not open for further replies. Froyo Jul 23, I'm not to clever when it come to what's going on with the processor side of things. But just been looking through my settings and saw that it says armv7 and not Snapdragon.
My Question is, is the armv7 the snapdragon??? And the CyanogenMod version Say's I was under the impression is was supposed to say Snapdragon and Cyanogenmod 11s. Can some please fill me in. Ice Cream Sandwich Jul 23, Did you buy the Chinese OPO as well?

If yes what was qemu release version? I mean run with. I also bet it would work with -M vexpress-a15 -cpu cortex-a15 but I didn't test that. If you want to try it out, just copy exactly what Buildroot saysand it will work as usual. Tested in QEMU 2. Learn more. Ask Question. Asked 3 years, 11 months ago.

That too, but also its sometimes possible to fix things by applying patches or cherrypicking commits from gitrepo, which is some kind of programming. Active Oldest Votes.

It also benefits from an integrated L2 cache designed for low-power, with lower transaction latencies and improved OS support for cache maintenance. On top of this there is improved branch prediction and an improved memory system performance, with bit load-store path, bit AMBA 4 AXI buses and increased TLB size entry, up from entry for Cortex-A9 and Cortex-A5increasing performance for large workloads such as web browsing.
In a 28nm process, the Cortex-A7 can run at 1. This lowest performance profile makes it an ideal standalone processor for a range of mobile devices, and means the Cortex-A7 can ultimately deliver similar performance to the Cortex-A9 processor at much higher levels of power efficiency. For system designers and software engineers, the Cortex-A7 manual provides information on implementing and programming Cortex-A7 based devices. Common to all Cortex-A series processors, this programmer's guide is useful for assembly and C language application development for Armv7-A.
Arm and our partners provide specialist code generation, debug and analysis tools for software development on Cortex-A series processors, such as DS-5 Development Studio. Arm training courses and on-site system-design advisory services enable licensees to efficiently integrate the Cortex-A7 processor into their design to realize maximum system performance with lowest risk and fastest time-to-market.
The Cortex-A7 processor is fully supported by Arm development tools. Related IP includes:. Mali Display Processors. Mali-V Video Processor. CoreLink Network Interconnect Family. Interrupt Controllers. CoreSight SoC DS-5 Development Studio. Fixed Virtual Platforms.
