The following is probably the fastest possible text output routine for the CPC in Mode 2, coded by [[Prodatron]] for the [[SymbOS]] [[SymShell]] fullscreen modeincluding strong optimization ideas by [[MaV]] and one 1NOP tweak by [[BSC]]. It needs between 84 61 and 92 68 microseconds per char, depending on the amount of 0- and repeating-bytes within a char matrix contains. For average english texts 65 microseconds (a little bit more than 1 raster line) per char is needed. That means that a complete 2000char screen with mixed text is filled in 0,176 13 seconds.You can still accelerate it by simplifying the font to increase the amount of repeating-bytes within a char matrix. Another possibility is to move the whole main loop to each single char routine. That would only save one microsecond but blow up the whole code by about 2KB. == Actual version (v2.1) == This is the actual version from 2014. It has a size of about 3,5KB.

In this case you would save additional 5 microseconds (short == Original version == This is the old version from 2005. It has a size of 6%)about 3KB. The routine actual version is OS510 bytes larger but has several improvements:* optimized inchar-friendlyscreen-line-jump by using SET x, as it H/RES x,H instead of ADD HL,x (idea by [[MaV]])* this keeps BC free, which now doesn't touch need to be defined for every char and is used for the char counter and for the repeating bytes inside a char matrix* 256byte aligned jump table, limited to 128 chars to speed up jump table access* loop-handling moved from main loop to each single char routine to save one JP instructionThat all together makes the actual version more then 30% faster compared to the 2nd register setfollowing version.
