Hiya Folks, I wondered if anyone had any experience or could offer any insight into this. I've converted my 68K asm draw routines into ARM C code and noticed a substantial slowdown. Upon closer inspection it seems that the overhead for calling an ARM function using PcrNativeCall is extremely high. I'm calling it around 40 times per game cycle and it's taking approx 2 ticks just for the call.
Does anyone know if there is any technique to reduce this overhead, a faster way to call arm code perhaps? Also when it comes to efficiency on a Palm which is the way to go Arm instructions or Thumb or ins't there much speed difference between the two?
