Machine Scheduler on Power PC: Latency Limit and Register Pressure
Hi,
I've been looking at the Machine Scheduler on Power PC. I am looking only
at the pre-RA machine scheduler and I am running it in the default
bi-directional mode (so, both top down and bottom up queues are
considered). I've come across an example where the scheduler picks a poor
ordering for the instructions which results in very high register pressure
which results in spills.

Vectorizing a function that needs to access previous elements of a row
Hi,
I'm a newbie when it comes to R, and I'm trying to figure out how to use
vectorization as opposed to for loops. In particular, how can I create a
function that is applied on each element of a row, but can access previous
elements relative to that element?
My problem: I want to calculate something like x[i] = x[i] / x[i - 1] for
each element of a vector x:
ex.
x <- data.frame(a

Question about Huffman Tables in Setup Header
There is bit space in Bitstream Header to put Huffman codes in.
However, This space can take only 80 kinds of Huffman code set.
And This space is divded into DC Huffman code set and AC Huffman set,
and There are only 16 choices in each DC and AC Huffman code set.
If we want to use this space, we find out best(or proper) performance
80 frequency counts(Huffman code sets) from tens thousands of frame.
Dose anyone have an idea or algorithm to find ou...
