One of the most amazing developments in the last few years has been the explosion in mobile gaming. Not so long ago, if you wanted to while away the time playing a game on your phone there were not many…

I attended the 2019 edition of SUSE conference. I take you through the the latest developments in enterprise Linux, OpenStack, CEPH and more, from the conference.

Arm Architecture v8.2 features were detailed in 2016. Just two years later, in 2018, flagship Android phones with ARMv8.2 features (Google Pixel3, Huawei Mate 20 Pro, Samsung Galaxy S9, etc) started shipping…

Arm now supports Android Neural Networks API (NNAPI) with open-source, optimized NN operators that deliver serious performance uplift across CPUs and GPUs

Arm is enthusiastic about Google’s announcement earlier this week encouraging Android applications to take advantage of the 64-bit Arm Architecture

This document demonstrates how to call the JNI, through a procedure : written with the GNU ARM Assembly syntax, assembled and stored in a ELF shared library, executed by an Android system through an…

Here's a little demonstration about how to generate a library, with an assembly procedure that will be called through the Java Native Interface, using an Android project as an example. The procedure will…

So, another bug I had to deal with NativeActivity and for which I have no clear solution but a workaround for.The problem I compiled a version of libnative-activity.so that depends on my own library, libmyy…

I passed half a day hunting weird bugs on Android's Native Activity.The one I'll talk about here is if glCreateShader suddenly returns 0 and glError sends you back 0x502 (GL_INVALID_OPERATION - 1282).I…

When applying ARM NEON to real-world applications there are many programming skills to observe. This article introduces common NEON optimization skills. NEON assembly and intrinsics will also be discussed…

Arm NEON programming quick reference guide.

Ne10 v1.2.0 is released. Now radix-3 and radix-5 are supported in floating point complex FFT. Benchmark data below shows that NEON optimization has significantly improved performance of FFT.1. Project…

In the newest version of Android, Lollipop (5.0), the virtual machine (VM) implementation has changed from Dalvik to ART. Like most VMs, ART has an interpreter for executing the bytecode of an application…

In this blog I will cover various methods of runtime feature detection on CPUs implementing ARMv8-A architecture. These methods include using HWCAP on Linux and Android, using NDK on Android and using…

This blog has been written before but quite a few things have improved in the ease of use and breadth of support of Streamline use on Android in the past few years. For starters, Mac OS X is well supported…

We would like to share with you an Android-based application that enables Intel software on ARM-based devices. To demo you this approach we took Intel version of DOOM and run it on Android-based device…

FFT feature in ProjectNe101 IntroductionProject Ne10 recently received an updated version of FFT, which is heavily NEON optimized for both ARM v7-A/v8-A AArch32 and v8-A AArch64 and is faster than almost…

In this blog post I give details of how I ported Android to the Samsung Chromebook model XE303C12. I do this in the hope of generating documentation which can be useful in other similar ports.

This blog was originally posted on 9 January 20131 IntroductionARM® NEON™ technology is a SIMD (single instruction multiple data) architecture extension for the ARM Cortex™-A series processors…

This blog describes how to get Android running on ARM-based SoC boards. We run through the overall procedure and point out potential pitfalls and other things that you may encounter.
