LT4335 opcode table. Version of 8 July 2011. Home.

Opcodes for instructions particular to data types:

Last several digits of opcode		float	integer	string
input-output	get embedded	…11_001	…01_001	…10_001
	other get	…101_111	…101_011	…101_101
	put	…011_111	…011_011	…011_101
	get-and-put combination	…111_111	…111_011	…111_101
	unused	…001_111	…001_011	…001_101
versus		…11_110_111	…11_110_011	…11_110_101
other		…0_111	…0_011	…0_101

Generally, …111 is for floats, …011 for integers, and …101 for strings. The pattern …001 might have been used for a fourth data type, but instead was assigned to the get embedded instructions which, because they contain twelve bits of data, consume a large part of opcode space. Unused is …00_001.

Generally, …101_xxx is for non-embedded get, …011_xxx is for put, and …111_xxx is for the get-and-put combination. Unused is …001_xxx.

For extends, input-output is accomplished with string-type instructions. Extend arithmetic does have specific instructions, opcodes for which are gleaned from leftovers in the integer range.

Opcodes for other instructions:

Last several digits of opcode		float	integer	string	always	uninterruptable
branch	without push	…11_000_010	…01_000_010	…100_010	TO DO 0_000_010 TO DO	…101_010
	with push	…11_010_010	…01_010_010	…110_010	TO DO 0_010_010 TO DO	…111_010
