Member Function Documentation
◆ addLoopIterReg()
|
inline |
Register reg as being the idx'th iter_args register for 'op'.
Definition at line 242 of file CalyxLoweringUtils.h.
References assert(), circt::calyx::LoopLoweringStateInterface< Loop >::loopIterRegs, and seq::reg().
◆ buildLoopIterArgAssignments()
|
inline |
Creates a new group that assigns the 'ops' values to the iter arg registers of the loop operation.
Pass iteration arguments through registers. This follows closely to what is done for branch ops.
Create register assignment for each iter_arg. a calyx::GroupDone signal is created for each register. These will be &'ed together in MultipleGroupDonePattern.

Member Data Documentation
◆ loopInitGroups
|
private |
Loop init groups are to be scheduled before the while operation.
These groups should set the initial value(s) of the loop init_args register(s).

Referenced by circt::calyx::LoopLoweringStateInterface< Loop >::getLoopInitGroups(), and circt::calyx::LoopLoweringStateInterface< Loop >::setLoopInitGroups().
◆ loopIterRegs
|
private |
A mapping from loop ops to iteration argument registers.
Definition at line 320 of file CalyxLoweringUtils.h.
Referenced by circt::calyx::LoopLoweringStateInterface< Loop >::addLoopIterReg(), and circt::calyx::LoopLoweringStateInterface< Loop >::getLoopIterRegs().
◆ loopLatchGroups
|
private |
A loop latch group is a group that should be sequentially executed when finishing a loop body.
The execution of this group will write the yield'ed loop body values to the iteration argument registers.
