Mathematical Opcodes

0b0000mdddooooooss (0xUUUUuuuu)

Use ALU(s) to do an operation. If m is 1 then all ALUs will be used, if 0 then only one ALU will be used. The 32-bit argument is optional. It must be included if u is used in the source or destination. It may not be included otherwise.

d (binary)	destination
000	(none)
001	ALURAM[U]
100	memory[U] (8-bits)
101	memory[U] (16-bits)
110	memory[U] (32-bits)

s (binary)	source
00	ALU A register
01	Uu
10	RAM[u]
11	ALURAM[u]

Jumps and Calls

0b001prccc_nnnnnnnn (0xNNNN)

Generic conditional and unconditional relative and absolute(long) call/jump format. p = 1 for call, 0 for jump. r = 1 for relative, 0 for absolute. In a relative call/jump n is added to the PC. In an absolute call/jump, the extra uint16 N is loaded and PC = (N << 8) | n

c (binary)	condition
000	always
001	never
010	z flag
011	nz flag
100	g flag
101	ge flag
110	l flag
111	le flag

Extended

0b11111111_0000rrrr 0xvvvv

Load video control register r with value v

r (binary)	register
0000	pixel clock divider * 2
0001	????
