[android-developers] Please help about Renderscript compute

Hi, all.

I am a newbie of Android development and I am developing an app for
image processing and I ported some filters to android.

However, the performance is not good and I read some articles pointing
renderscript is one of the way to boost performance.

I read some codes but I find it too difficult for me to understand.

I have a edge detection filter implemented in JAVA and I would like to
port it to RS.

I have read the Helloworld Compute code and I can see the root() is
processing one pixel each time and unpack it into a float4 variable.

However, in my code, I need to read not only one pixel data but
several to calculate the result and I use 2D array to store the
values.

How can I implement this in RS, computing more than one pixel in the
same time?
