native support for CP1600 extensions in LTO-Flash #19

Open artrag opened 4 years ago

artrag commented 4 years ago

LTO-Flash includes a huge amount of CP1600 extensions that can be essential for math coding and data manipulation.

Look at ATAN2, DIST, SUMSQ,MPYSS and many others Locutus_CP-1600X_Instruction_Set_Extensions_20191119a.pdf https://atariage.com/forums/applications/core/interface/file/attachment.php?id=679387

The latest documentation is in attach. A big step in the intybasic could be native support of these extensions, specific of the LTO cartridge

Adding MPY16 support seems almost trivial, as it could be included in the current macro MULT reg, tmp, const

Wow! This is amazing and opens a whole new world. I need to research it more in terms of assembler support, and what LTO-Flash cartridges supporting this, before doing any implementation.

I thought you were asking about the old protocol for hardware multiplication that indeed is fully supported as soon as using --jlp.
