Hi Timothy, It requires some extra effort if twiddles and input/output have different bit width. Since Opus uses int32 for twiddles, we are going to do the same thing.

Hi Jean-Marc, I have implemented fixed-point FFT with 32-bit twiddles. Now I want to evaluate the accuracy, what method does Opus use? I use function implemented inside Ne10 to calculate SNR. Any comment? | size | SNR (dB) | | 16 | 82.558587 | | 32 | 83.530298 | | 60 | 80.292433 | | 64 | 82.752950 | | 120 | 79.625077 | | 128 | 83.091260 | | 240 | 79.555263 | | 256 |

Thanks for the last info it was truely helpful. Anyways, I'm currently trying to implement 3D textures into yuzu, as far as I know they are twiddled in a different manner to 2D textures. Could one of you guys point me in the right direction? I've been meddling around: https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/nv50/nv50_tex.c but I can't see where the

Hi, Attached is the first version of the DCT callback. It's still a bit WIP, but now you have something to refer to when I'm rambling :) Best Regards, Thorvald -------------- next part --------------

That being said, I agree that for Neon it makes sense to use 32-bit

I want to backup from a windows machine to a Macintosh. All of the guides that I've seen describe the other direction. Worse, they all seem slightly different, or inconsistent. The first thing that I'd want to do should be simple: an rsync -az --delete of the entire drive, to back up all of the files. But that's not everything on the windows machine. And this is what I have not seen

Hello-- How do I twiddle the sound drivers? I'm not that experienced with kernel twiddling and driver loading. I have Redhat 9. My previous attempts to play with the kernel and load extra drivers always ended with a new kernel that wouldn't boot. I know asterisk doesn't like to play with sound interfaces that aren't full duplex. So, when I built the system, I saw the MSI

I ran across a problem today in which some code ran fine in regular operation but failed in a test case. I scratched my head and thought "why would running from within the test harness change the behavior of my code?" Clearly it was the Heisenberg uncertainty principle in action! :) I discovered the root cause was that the rspec runner is setting the magical ruby global, $KCODE, to

Hi, i''am trying to build a Gentoo Dom0-kernel booting a HP DL380 G6. Has anyone twiddled a working kernel configuration for this hardware? i do have the linux-2.6.32-xen-r1 sources checked out by portage and tried some configurations.

Hi Jack, I would have expected the Mips backend to be using these routines (or more likely something on top of them) to emit the contents of the data and text sections and thus have the bit-twiddling done by these routines. I take it that's not happening? Basically, this should already work without any additional infrastructure. If it's not, something is broken and bypassing the

Jim, I see routines that are already available to do the endianizing, but the data and text section contents don't have sizing for the individual elements as far as I can see so that I can endianize them. That is the part I am trying to solve, not the bit twiddling algorithm. Did I miss something? Jack ________________________________________ From: Jim Grosbach [grosbach at apple.com] Sent:

Hi @ll, while clang/LLVM recognizes common bit-twiddling idioms/expressions like unsigned int rotate(unsigned int x, unsigned int n) { return (x << n) | (x >> (32 - n)); } and typically generates "rotate" machine instructions for this expression, it fails to recognize other also common bit-twiddling idioms/expressions. The standard IEEE CRC-32 for "big

Back to the scenario in my email of Jan. 3: We have objects with some large (or very large) components and some other components as well. We need to modify the smaller stuff but are not changing the big data. How can we avoid copying the big data? (A use case might be some modeling of large data where we want to save various versions, all including the same original data but differing in

I recently built openssh 2.1.1p1, under solaris. I noticed that I had problems running scp. It seems that it could not find the executable on the remote end. This was odd, becuase it existed in /usr/local/bin, publically executable, and /usr/local/bin/was in the users' normal PATH (exported, even). So finally, I twiddled the source to make it call /usr/local/bin/scp, instead of just

Hi, Whilst doing some QA work on XORP on my desktop, which has fxp0 and msk0, fxp0 got totally hosed. I was running PIM-SM and IGMPv2 router-mode on the box at the time. I wonder if this is related to the problems with fxp multicast transmission I saw back in April. I'm a bit concerned about this as fxp is still a very widespread and useful network chip. I am running

Hi all, The linking problem I found yesterday appears to be because of the built-in iconv in OS X. So, this is a request for patch or pointers: What needs to happen with configure.ac or the iconv.m4 macro file to link an iconv library _besides_ the one in /usr/local/lib? That's the tl;dr, full explanation follows. That library lacks the x86_64 architecture: $ file

Hi all: I'm trying to rebuild the anaconda installer for Centos 4.0 (i386) to add some RPMs and do some other things, and I've run into a problem. I've done lots of anaconda rebuilds for Tao Linux 1.0, and I'm bringing those bits forward into Centos 4.0. The all-knowing web hasn't turned up anything useful. It looks like the PXE-loaded kernel unpacked and mounted the

I know i''m probably doing something REALLY stupid.....but for some reason i can''t get send/recv to work over ssh. I just built a new media server and i''d like to move a few filesystem from my old server to my new server but for some reason i keep getting strange errors... At first i''d see something like this: pfexec: can''t get real path of
