Re: Book project "The Crackers" - Let's make this happen

Hey,

I'd like to participate, as I don't have a palpal account, I asked my bank to allow a german IBAN for transferring money. This may take a couple of days+another couple of days to register the IBAN.
Is there another way (credit card would be my best choice)?

Cheers,
Jean

Re: Algorithm to count colors/line and globally

Will try ... even If this is a memory killer compared to allocating 2MB for bitarray.
Hoping it will speed up significantly.
Will update this evening probably.

Re: Algorithm to count colors/line and globally

Hi Thorsten,
Yep will do on hatari to to check
Need 64mb as i have to keep track of colors for the whole image as well.

Re: Algorithm to count colors/line and globally

Hi, I'm back with some results: method1: (from me) use simple 32bit color table to count colors on a line and a bitarray of 16M colors to count colors on full image method2: (from seedy) sort 32bit colors on each line, reduce array to count colors on a line and add this reduction to build a dynamic ...

Re: Algorithm to count colors/line and globally

Hi mrbombermillzy,

thanks for the proposal but I don't think it could help me:
- I assume no fixed size for image, this shall work on big images as well
- I already 'simplified' the bit depth (24-->16bpp) similar to yours, hoever this time I want to find the exact number of colors

Cheers,
Jean

Re: Algorithm to count colors/line and globally

Hi seedy, yep basically this is about generating a new image containing only unique colours of the original one. I think I have enough information to start coding this now. Right now my approach would be: - Allocate one array of pixels to store a line to sort - Allocate a buffer around 600KB to hold...

Re: Algorithm to count colors/line and globally

Hi seedy, interesting :-) To make sure I understand it properly: We have to have 2 buffers holding unique colors (so n x 32bits for optimal speed): - A: One for the current line - B: One for the whole image For each line of the image: - Duplicate the line to temporary buffer A (else image will get c...

Algorithm to count colors/line and globally

Hi all, inspired by this thread http://www.atari-forum.com/viewtopic.php?f=27&t=38492, I started thinking about a LDV for VISION able to report the number of unique colors per line and globally for an image. And here is it as part of VISION current beta release: http://vision.atari.org/download/temp...

that is pretty weird on my side as well; orcs (32 or 64 bit) does not show any window, not even an icon in launch bar. I can see just the process in task manager. Using a Win10 64bit.

Hi Thorsten, not aware of GEMSCRIPT; just googled a bit, apparently it is for application communication and requires usage of windom.

Re: fastest way to copy a memory block in 68060 assembly

Hi, You can lose all the a0 leas and almost all the a1 leas by using (a0)+ and then addressing to d(a1). ? Don't get it. BTW in my cycle calculation I forgot to include these lea, so it's 228+8+8=244 (movem.l) vs 260 (move.l) Well not that better, assuming I'm correct on cycles hwich is pretty risky...

Re: fastest way to copy a memory block in 68060 assembly

Yep sure considering the amount of memory to move, need a loop counter anyway else code size would be too much.
Don't know how big 68060 instruction cache is (BTW why 68060?) but idea is to get as close as possible as this cache size and loop on n rept of movem.l

Re: fastest way to copy a memory block in 68060 assembly

Hi,

How does the rept(movem.l ...) based routine compares in term of clock cycles to the rept( move.l (a0)+,(a1)+ ...) ?
Estimating CPU cycles is a bit too far way in my mind but just for curiosity if someone has already sone the maths I'll appreciate.

Thanks,
Jean

Make .prj from CLI

Hi,

in order to automate some prg generation, I'd like to automate "Make all" menu entry from PureC from command line.
Is there a way to do this or this kind of "make all" can only be initiated from PureC GUI?

Thanks,
Jean
