assembly - Data alignment in store instruction -

-

in arm assembly, have data across registers r3 - r9. want store them memory using stm instruction starting address have in r0

instruction stm r0,{r3-r9} put data registers right next each other. want have 16-byte gap between stored values, e.g like:

str r3,[r0] str r4,[r0,#16] str r5,[r0,#32] str r6,[r0,#48]  ...

is possible stm instruction or there shortcut trick?

the stm instruction lets specify whether destination address should grow downwards or upwards, not stride should (it'll size of register, i.e. 1 word). you'll have use alternative solution 1 suggested yourself.

for example:

str r3,[r0] str r4,[r0,#16] str r5,[r0,#32] ....

or

; simpler since it's obvious stores spaced 16 bytes apart, ; altough doesn't preserve original value of r0 above version str r3,[r0],#16 str r4,[r0],#16 str r5,[r0],#16 ....

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

Image
i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
