Instruction set
General Info
It looks like instructions are 8 bytes long. Roughly speaking - first 4 bytes contain opcode and addressing mode. Second 4 bytes contain operands encoding.
Bit encoding used in this reference:
| value |

| 0 |

Predicates
Not sure about predicates yet, but they are used to mask execution of certain instructions.
Notation is the following:
<predicate> <instruction>
For example:
!p0 mad.f32
To reduce amount of examples - they are not listed with predicates.
It is assumed that all predicates are applicable to all instructions in the group unless opposite is indicated.
Operands
Currently - only known form of operands is registers.
Instructions may have up to four operands specified.
In this documentation they will be encoded as:
<op0> <op1> <op2> <op3>
Registers
- pa - primary attribute register. 32 bit long.
- sa - secondary attribute register. 32 bit long.
- o - output register. 32 bit long.
- r - temporary register. 32 bit long.
- i - internal register. 128 bit long.
Register Selector RS2
This encoding uses 2 bits to encode register type.
selector is encoded as:

|

|
Note that internal registers are not encoded - they are reserved in Register R6
Register Selector Indexable RSI2
This encoding uses 2 bits to encode register type.
selector is encoded as:
| 1 |
0 |
meaning
|
| 0 |

index
|
When index mode is used - there has to be another field that encodes index expression with Register Index Offset RIO6
The way that index expression is buit:
<reg>[index1 * 2 + <offset>]
Example:
r[index1 * 2 + 8]
Register R6
This encoding uses 6 bits to encode register index.
register is encoded as:

index is calculated as: value * 2
Register expression is built as:
<reg><index>
Example:
sa68
Specific type of register can be selected with Register Selector RS2
For destination operand op0 specific type of register can be selected with Register Selector Indexable RSI2
Last 4 values are reserved for internal registers i0, i1, i2, i3

rt is encoded as Register Selector RS2
offset is calculated as: value * 2

Example:

Modifier and dest data format
At the moment it is not known which of the data format fields is dest and which is source.
This is the reason why term modifier is mixed with term dest data format.
