EXECUTABLE INSTRUCTION OPCODES
|
|
|
|
Instruction opcodes all start with a % character and have 0 or more
|
|
operands. In no case are there more then 3 operands.
|
|
|
|
|
|
* %assign <var-label>, <delay>, <bit>
|
|
|
|
This does a non-blocking assignment to a variable. The <label>
|
|
identifies the affected variable, and the <delay> gives the delay when
|
|
the assignment takes place. The delay may be 0. For blocking
|
|
assignments, see %set. The <bit> is the address of the thread register
|
|
that contains the bit value to assign.
|
|
|
|
* %delay <delay>
|
|
|
|
This opcode pauses the thread, and causes it to be rescheduled for a
|
|
time in the future. The <amount> is the number of the ticks in the
|
|
future to reschedule, and is >= 0. If the %delay is zero, then the
|
|
thread yields the processor for another thread, but will be resumed in
|
|
the current time step.
|
|
|
|
* %load <bit>, <functor-label>
|
|
|
|
This instruction loads a value from the given functor output into the
|
|
specified thread register bit.
|
|
|
|
* %set <var-label>, <bit>
|
|
|
|
This sets a bit of a variable, and is used to implement blocking
|
|
assignments. The <label> identifies the variable to receive the new
|
|
value. Once the set completes, the value is immediately available to
|
|
be read out of the variable. The <bit> is the address of the thread
|
|
register that contains the bit value to assign.
|
|
|
|
* %waitfor <functor-label>
