Param is VU0 (MICROPROGRAM) memory offset, | Param is VU0 (MICROPROGRAM) memory offset, keep in mind this offset is a direct address.<br> | ||
So by PS2 memory mapping is ((offset + 0x11000000) & 0x11000FF8)<br> | |||
Function is somehow related to all Upper pipeline ADD/SUB operations (incl. opcodes like MADD, OPMSUB, etc.).<br> | |||
When offset is hit, opcode is processed using different code path, probably more accurate.<br> | |||
Note: Due to how VU work, exact offset in VU memory will be param + 4, because VU process 2 opcodes in same time.<br> | |||
Lower pipeline fetch opcode from address, Upper from address + 4. | |||
