GLOBAL_STACK_SIZE
I am having trouble understanding the stack allocation scheme when using a
C55xx device. From what I can tell, the GLOBAL_STACK_SIZE is set in arch.h
to 100,000 bytes (when using FIXED_POINT), which is then used in the
ALLOC_STACK macro found in stack_alloc.h. This macro seems to say, if
global_stack==0, then call celt_alloc_scratch, found in os_support.h, which
in turn attempts to allocate (using

Another Error For TI C55x C Compiler
hey guys, I am using the tip of Git and attempting to compile for a C55x
DSP. I am running into a couple compile errors and have found the source of
the issue.
The errors:

stack + heap sizes
??
hi ?Jean-Marc,
?
thanks for your answer.
But still I am struggling to find a reasonable upper limit for the RAM sizes.
?
You say we need 4.5/9.0 kB for enc/dec per channel.
But are those sizes really independent of any settings, like frame_size,
bitrate, complexity, etc. ?
?
at least in our configuration I find these requirements:?
?- native stack: < 2.1kB (enc or dec) measured by RealView

fixed point code
Hi,
I am looking into fixed-point code of the CELT decoder for real-time application. Here are some questions..
[1] array, window[]
The array, window[] is being initialized from a function below in modes.c. This array is being initialized differently for the decoder, depending on frame size and sampling freq. of the bitstream ..
Could you provide us with fixed-point code for initialization of

Porting CELT to the C5515
Jean-marc,
I am trying to port CELT to the ti dsp c5515. I counted a problem when I
try to call a function:
len = celt_encode(enc, in, frame_size, data, bytes_per_packet);
I guess that the problem in the stack allocation variable defined in the
header file stack_alloc.h.
For more info over my platform settings, see the attached files. May be

Global stack on Cortex-M4
Hi all !
I just learned about the Opus codec and would like to try it out on my
NRF52 (Cortex-M4) target. I've been struggling a bit with the
"trival_example.c" setup but repeatedly run into "hard fault" crashes
when stepping through the code.
Firstly; for a "bare bone" configuration, does the following compiler
directives make sense ?

get mean from cdf
Hi All,
How can I get the expected value from a discrete cdf? Is there any R
function that can do this?

sporadic slow/non response, problems copying to sent folder
After experiencing these symptoms through many of the release
candidates, we've been at v1.0.0 now for a few weeks, and they're still
there. Perhaps a config issue with my setup (mbox locks?). It's really
too disrupting to continue using this way. I've included symptoms,
client info, mta info, log entries and config file. What other
information can I provide? Please

How can I get the indices of the minimum elements in a matrix without using

For example, if the matrix is

generalized linear models
Hi, R users,
I am trying to use glm to do logistic regression. I know generally when I
have two covariates, say x1 and x2, then I do
fit <- glm(y~x1+x2,famliy='binomial')
But now my covariates form a n*p matrix, say x, so actually each column is a
covariate. So I think I should do
fit <- glm(y~x,family='binomial')
Then I need to predict new data. How should I write the

2-dim density plot
Hi All,
I have a 2-dim density defined on 0<x<1, 0<y<1, x<y. I know the exact
formula of the density. How can I visualize it? What plot functions can I
use?
Thanks,

[PATCH v2 1/1] xen/netback: correctly calculate required slots of skb.
When counting required slots for skb, netback directly uses DIV_ROUND_UP to get
slots required by header data. This is wrong when offset in the page of header
data is not zero, and is also inconsistent with following calculation for
required slot in netbk_gop_skb.
In netbk_gop_skb, required slots are calculated based on offset and len in page
of header data. It is possible that required slots

variable selection in logistic
Hi, R users,
What may be the best function in R to do variable selection in logistic
regression? I have the same number of variables as the number of samples,
and I want to select the best variablesfor prediction. Is there any function
doing forward selection followed by backward elimination in stepwise
logistic regression?
Thanks,

iperf problem with Windows SMP VM
Hi
I am developing Window pv network driver and hit a problem now.
My server use Xen 3.1.4 and have 2 physical CPUs. When I create two VM
with 1 VCPU on a same server, iperf performance is OK between those two
VM, but there is performance degradation between those 2 VM when i
increase VCPU from 1 to 2.
This problem occurs in QEMU mode too.
Does Xen 3.1.4 has such problem or anything wrong

[PATCH] hvm: Correct RTC time offset update error due to tm->tm_year
Hi
In rtc_set_time, mktime is called to calculate seconds since 1970/01/01,
input parameters of mktime are required to be in normal date format.
Such as: year=1980, mon=12, day=31, hour=23, min=59, sec=59. However,
the current input parameter of mktime is tm->tm_year, and it is the
number of years since 1900. (For example, if current time is 2012/12/31,
and tm->tm_year is 112). This is

penalized logistic regression
Hi, R users,
Is there any package for penalized logistic regression with more than two
response classes? I read the manual for stepPlr, but it seems it's only for
binary case.

Is there any function in R that does the exact test for the matched pair

help about solving two equations
I have two matrix s1 and s2, each of them is 1000*1.
and I have two equations:
digamma(p)-digamma(p+q)=s1,
digamma(q)-digamma(p+q)=s2,
and I want to sovle these two equations to get the value of x and y, which are also two 1000*1 matrices.
I write a program like this:
f <- function(x) {
p<- x[1]; q <- x[2];
((digamma(p)-digamma(p+q)-s1[2,]) )^2 +((digamma(q)-digamma(p+q)-s2[2,]) )^2
