Hi, I am using speex 1.2beta2 on a narrowband 16-bit, 8khz system that has a severe program space problem and will not fit speex in its normal operation. In an attempt to shrink speex I placed a breakpoint in every function and ran a decode and encode and removed the breakpoints that I hit. in the functions that had a breakpoint that I didn't hit I commented out those functions (as well as

for the bits init I am using speex_bits_set_bit_buffer and I don't use the write to or read from because the data is already in the buffer I am reading from and I am writing to the final buffer so I don't need to move arrays around. what part is the vocoder part of the decode? Thanks for your help! -Mike >>> Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> 08/06/07

I'm glad to hear that my data size can be shrunk considerably, however I do not know the minimum values that I would set the static arrays to be. I hate to be a bother but could you tell me the minimum values for these arrays/structures in the state structure?

Am I wrong that barplot is supposed to just skip NAs, and continue with the rest of the data in a matrix column? That's how I read various posts on the subject. But that's not what happens for me with R64.app (on a Mac, obviously). For example: d0 <- as.matrix(c(2,3,4)) d1 <- as.matrix(c(2,3,NA)) d2 <- as.matrix(c(2,NA,4)) d3 <- as.matrix(c(NA,3,4)) barplot(d0) barplot(d1)

tag 334917 = patch thanks Hi, I?ve fixed the m68k syscall of klibc and made it able to use six-argument syscalls like mmap2. However, I could not yet fully test it (only mostly; opendir() specifically fails) due to: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47533 @m68k porters: Please have a look at the gcc bug as well. @klibc: Please apply the patch, it?s better than what we have, and

Forwarding Oleg's mail as he seems to have troubles with posting to mailing list. Sorry for top posting, I could not reply and forward at once. Btw, your "read-only access" may happen if you're posting from different mailing address then one from which you subscribed. re: conflicting names To avoid conflict functions in math_approx.h should be wrapped by OVERRIDE_FUNC_NAME

> This isn't really my area of expertise, but I think you're messing up > your RegisterClass definition. Look at how ARM defines DTriple. DTriple is untyped :) , because we do not have any valut type which defines 3xi64. However, the paired register needs to have type. Fabian, what are the definitions of ER and DR register classes? -- With best regards, Anton Korobeynikov Faculty

Hello! I have an old Dell Latitude C800 laptop (with Pentium3 CPU in it). FreeBSD 6.3-STABLE was running fine on it, but I decided to update the machine to 9.1-STABLE. Well, neither my own custom kernel, nor even the official 9.1-RELEASE CD1 would boot... In both cases the boot process runs up to detecting uhub0, then either hangs forever or shuts off after a short while. Again, I thought I

Hi List l am interested in developing price model. I have found a research paper related to price model of corn in US market where it has taken demand & supply forces into consideration. Following are the equation: Supply equation: St= a0+a1Pt-1+a2Rt-1+a3St-1+a5D1+a6D2+a7D3+U1 -(1) Where D1,D2,D3=Quarterly Dummy Variables(Since quarterly data are considered) Here, Supply

I tried to speed up Dhrystone on ARM Cortex-A8 by optimizing the memcpy intrinsic. I used the Neon load multiple instruction to move up to 48 bytes at a time . Over 15 scalar instructions collapsed down into these 2 Neon instructions. fldmiad r3, {d0, d1, d2, d3, d4, d5} @ SrcLine dhrystone.c 359 fstmiad r1, {d0, d1, d2, d3, d4, d5} It seems like this should be faster. But I did

Hi all, I have an ARM virtual machine with ubuntu and want to port LLVM over that. In release documents, ARM is not in the list of supported platforms. I tried to compile LLVM on ARM platform and ran into an error. Has anyone tried to port LLVM onto ARM before? Is it going to require lots of changes?

Hi, after a year, I decided to hack on klibc again. I?ve reworked both the patch to add mkstemp(), discussing to use AT_RANDOM as cheap entropy source on IRC (if there will ever be another entropy consumer, I can quickly write a minimal arc4random() seeded from it, as it has only 16 octets), capable of making a working mksh (static and shared) on amd64/xen, and the m68k support code, leading to

Hi Guys, My Debian box has been hacked a few days ago using an OpenSSH vulnerability. Subsequently my box was used for sending spam and as a hacking platform (according to my ISP). I was running a fairly recent version of OpenSSH (3.9p1). I reinstalled my box (now with 3.8p1 as supplied by Debian Stable), and started tcpdump to see if I would get lucky. I DID!
