ReductionTreeGenerator class

Reduction Tree Generator that produces a recursive tree computation inline so that the operation can access global signals.

Constructors

ReductionTreeGenerator.new(List<Logic> sequence, Logic operation(List<Logic> inputs, {Logic? control, int depth, String name}), {int radix = 2, dynamic signExtend, int? depthBetweenFlops, Logic? control, Logic? clk, Logic? enable, Logic? reset})
Generate a tree based on dividing the input sequence of a node into segments, recursively constructing radix child nodes to operate on each segment.

Properties

clk → Logic?
Optional clk input to create pipeline.
final
control → Logic?
Optional control input to input to operation.
final
controlOut ↔ Logic?
The control output of the tree computation.
latefinal
depth → int
The depth of the tree from the output to the leaves.
no setter
depthBetweenFlops → int?
Specified depth of nodes at which to flop (requires clk).
final
enable → Logic?
Optional enable input to enable pipeline.
final
hashCode → int
The hash code for this object.
no setterinherited
latency → int
The number of flops from the output to the leaves.
no setter
operation → Logic Function(List<Logic> inputs, {Logic? control, int depth, String name})
Operation to be performed at each node. Note that operation can widen the output. The logic function must support the operation for 2 and up to radix inputs. The depth input is the depth of the current node in the tree to the leaves. For sequences that are not powers of radix, the depth is the maximum depth to the leaves from this node in the tree. The depth can be used to index the control Logic to change behavior at each depth of the tree.
final
out ↔ Logic
The final output of the tree computation.
latefinal
radix → int
Specified width of input to each reduction node (e.g., binary: radix=2)
final
reset → Logic?
Optional reset input to reset pipeline.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sequence ↔ List<Logic>
The input sequence
latefinal
signExtensionParameter ↔ StaticOrRuntimeParameter
Configuration for signed extension of values in the tree.
latefinal

Methods

noSuchMethod(Invocation invocation) → dynamic

A string representation of this object.
