similar to: [LLVMdev] Using LLVM on an embedded device

Hi, I am researching a possibility of running LLVM components (such as JIT) on an embedded device, where the memory footprint and RAM usage are the main concerns. So I was wondering if anyone could share their experience with running LLVM on an embedded device. What is the approximate code footprint that we are looking at? For example, on an x86 with a minimum set of optimizations and with

I want to compare the memory footprint of LLVM JIT vs the Interpreter on Darwin. I am currently doing this by running lli, on a simple but long running program, with and without the "-force-interpreter option", and then I look at the Real Memory used by lli in the Activity Monitor. I currently observe that the JIT takes 4.0MB and the Interpreter takes 1.7MB. Are these values close to

can you post the simple but long running program?

Hi All, I've been reading through the archives, and am still reading through now, but I figured I would ask this anyways. My task is to support domain users and groups on an embedded network device using Samba 3.0.14a (upgrading would be difficult, due to the qualification testing our QA department would require). I'm trying to determine the minimum set of required libraries and

Hi all, I am interested in using the OPUS codec for real-time application on an (preferable low-profile) platform. In order to choose the optimal processor (memory size, speed,...) I have the following questions: - We have compiled OPUS on a PC with Linux OS and on a dual-core Cortex A9 with Linux Kernel. Can OPUS run on a processor with no specific OS, or are there

Hello everyone, I tried integrating opus middleware on an STM32L4 microcontroller based project. First thing I noticed is the considerable amount of memory allocated by the opus_encoder_create function (nearly 40 kbytes if I recall). After modifying my project's memory setting (mainly heap size adjustments), I could bypass some aspects of this problems. What I'm noticing now is the time

Hi Everybody, my rails 1.2.5 application runs in a linux embedded environment with serious memory constraints. I would need to know how small a memory footprint I can hope to get. I run ligthtpd with only one dispatch and I did already remove actionmailer and actionwebservice which I do not need. Currently top shows a memory footprint of 720K for lighttpd and 25M for the dispatch.fcgi process. The

Using centos 5.2, I want to use a kickstart file to select packages in order to have an unattended install onto a bare-metal server. Is there any way of finding out which packages I need to compile, build and run asterisk ? I generally want to build all modules in asterisk and the wct4xxp zaptel module I want to be able to not select any groups in the kickstart file, but only select

Does anybody have experience of implementing Speex encoding on low-power, low-cost bare-metal embedded hardware? I'm trying to get a feel for minimum possible hardware upon which it is possible to get a reasonable working implementation of Speex encoding. I can find little in this area on the website or via Google. Thanks, Henry

If you look at low cost (~$10 to $20 at quantities) fix-point DSPs (TI C5416 for example), they don't have a lot of on-chip RAM. 5416 has 128k, which is already a lot. Of cause you can use external RAM, but this not only will increase cost and board space, but will also degrade performance a lot. Many of the speed-enhancing tricks only work with on-chip memory. Once you go off chip, you lost a

I'm seeing a lot of activity over the last two days with what looks to be a kiddie script. Mostly trying to access several of our servers with the username anna. All failed... in fact I don't think we have a user anna on any of our servers. Meanwhile... I'm running Sendmail. This pertains to Centos 4 and 5 servers. I'm also running fail2ban on some and Ossec on others. So far,

Dear List, how can I obtain the value of r suqared for a non-linear model? For linear models it can be found in the summary() of the model but for non-linear models I just don't know. Please help! Anna

What is an alternative X window manager, supported by CentOS, that has very small memory footprint? I want to avoid twm, because it defaults to interactive placement when not giving geometry options.

Hi everyone (again), before you all start screaming that the reordering of factors has been discusse on several threads and is not particular to ggplot2, hear me out. I can easily reorder my x-axis factor in facet.grid() in ggplot2. What I cannot reorder are the factors represented on the strips. I can see that the graphs are changing, so I am afraid of what it is I am doing. Why is ggplot2

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What is the expected footprint of a tool using the LLVM JIT? I have created a simple project that uses the LLVM C++ API to JIT calls to XPCOM method signature... it works well, but the component DLL is very large (Linux x86-74, 5.8MB optimized and stripped). Is this normal? Am I linking to "too much" or not using the correct link flags?
