ACE CoSy Compiler Framework Outperforms LLVM by up to 25% for ARM9 processors

ACE (Associated Compiler Experts) announced that their 2012 CoSy compiler development system delivers better performance than the latest LLVM 3.0 compiler on ARM9 processors. Using an ARM9 processor as reference, CoSy compiler framework (2012) shows more than 15% performance improvement using Livermore benchmark loops and 25% in MiBench against LLVM 3.0. The CoSy compiler framework is also more than 7% ahead of LLVM on the EEMBC CoreMark benchmark. The company explains this feat by the use of “CoSy’s unique flexible phase ordering of cutting-edge code optimizations and the addition of new CoSy features” such as compile-time code generator feedback injected into optimization algorithms in order to augment realistic and accurate decision making in architecture-independent optimizations. ACE did not publish the benchmark results publicly, and I could not find any reference to “cosy” or “ace” in EEMBC Coremark database, so I could not check those results myself. CoSy Compiler Framework is […]

72.90 USD AK802 Android Mini PC with AllWinner A10 and 1GB RAM

No, it’s not a typo in the title, and I did not mean to write “MK802”, but a company (which does not appear to be Rikomagic) released a product called AK802 which looks very similar (not to say exactly) the same, but comes with 1GB by default. Here are the specifications of the device partially taken from Dealextreme, so there must be an error somewhere, we just need to find out where ;). CPU AllWinner A10 @ 1.5GHz + Mali 400 GPU Memory 1 GB RAM Storage 4 GB Flash microSD slot (Up to 32 GB) Connectivity WiFi 802.11b/g USB micro USB 2.0/OTG port USB 2.0 Host port Video output HDMI (up to 2160p) Video Codecs & Containers WMV, ASF, MP4, 3GP, 3G2M4V, AVI, MJPEG, RV10, DivX/VC-1, MPEG-2, MPEG-4, H.263, H.264/1280*720P HD 30 fps, 1080P/720*480 D1 30fps Audio Codecs AAC, AAC+, eAAC+, AMR-NB, AMR-WB, QCP, MP3, WMA, WAV, MIDI, M4A […]

Quick Binary Debugging in Linux with Strace System Call Tracer

I’ve recently come across strace, a debugging utility for Linux that “monitor the system calls used by a program and all the signals”. It may not be that useful if you have the source code and can run other debugging tools such as gdb, or simply add printf to your code. But if you don’t have source code of the program, or you are a system administrator who wants to check if the program fails due to file access reasons, for example, this is really a great tool as it may help you find out which file causes problem. In my case, I was trying OpenGL ES on an ARM platform, and at least part of the code comes in libraries that are only available in binary form. I got the following error message running es2_info (part of mesa-utils-extra): UMP: ump_arch_open() failed to open UMP device driver ********************************************************************* ERROR: In […]

Kontron Unveils KTT30/mITX Nvidia Tegra 3 Mini-ITX Board

Kontron has today unveiled the KTT30/mITX, its first embedded ARM based Mini-ITX board (and the first ARM mini-ITX board I’ve ever heard of). The motherboard is powered by Nvidia Tegra 3 quad core processor @ 900 MHz with up to 2 GB DDR3L memory, and consumes less than 7W. Storage is available via 2 SD Card slots, one bootable eMMC, and one SATA 2.0 port. The company expects this ARM Mini-ITX motherboard to be used in applications such as thin clients, Panel PCs, digital signage and Mini-Box PCs. The solution is also suitable for industrial (rail road, instrumentation…) and medical fields as it will be available for at least seven years. By using the Mini-ITX form factor, Kontron KTT30/mITX board can be easily integrated in existing embedded solutions using (x86) mini-ITX boards. Here are the key features of Kontron KTT30/mITX motherboard: SoC – Nvidia Tegra 3 ARM Cortex-A9 Quad Core […]
