Worked Examples

Encodings and arithmetic are checked against the specification. The multiply, fill and triangle programs also pass the C model used by the RISC workbench. They have not been tested on a V2200 board.

Example	Contents
Decode an instruction word	Opcode byte, operand indices, byte order, signed multiply and signed branch offset.
Build a DMA list	A transfer command and terminating null link, with exact word values.
Fill a scan line	Format, mask and color registers; operand pair; write hazards and completion polling.
Set up a triangle	Pixel state, fixed-point coordinates, edge gradients, shadowing and launch order.
