What I mean to point out is that while you seem to think the newer one is better, I accidentally ran it at the wrong AHB and thus memory speed. This means the old version is no worse than the newest version. Tests that I ran at AHB = 66 MHz with the old version support this.

Hum yeah, well we'll see how it goes with writing to "normal" memory.

Bump,

so this writes 1000 times a 320*240*2 bytes buffer in RAM to another similar buffer in RAM. Start timing when the screen goes black, one second after you ran the program.
