PartialProductGeneratorNoSignExtension class

A Partial Product Generator with no sign extension

Inheritance

Constructors

PartialProductGeneratorNoSignExtension(Logic multiplicand, Logic multiplier, RadixEncoder radixEncoder, {required bool signed, Logic? selectSigned})
Construct a basic Partial Product Generator

Properties

encoder ↔ MultiplierEncoder
Encoder for the full multiply operand
latefinalinherited
hashCode → int
The hash code for this object.
no setterinherited
isSignExtended ↔ bool
Used to avoid sign extending more than once
getter/setter pairinherited
multiplicand → Logic
The multiplicand term
no setterinherited
multiplier → Logic
The multiplier term
no setterinherited
partialProducts ↔ List<List<Logic>>
Partial Products output. Generated by selector and extended by sign extension routines
latefinalinherited
rows → int
rows of partial products
no setterinherited
rowShift → List<int>
The actual shift in each row. This value will be modified by the sign extension routine used when folding in a sign bit from another row
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
selector ↔ MultiplicandSelector
Selector for the multiplicand which uses the encoder to index into multiples of the multiplicand and generate partial products
latefinalinherited
selectSigned ↔ Logic?
If not null, use this signal to select between signed and unsigned operation.
latefinalinherited
shift → int
Get the shift increment between neighboring product rows
no setterinherited
signed ↔ bool
Operands are signed
latefinalinherited

Methods

addStopSign(List<Logic> addend, SignBit sign) → void
Helper function for sign extension routines: For signed operands, set the MSB to sign, otherwise add this sign bit.
inherited
addStopSignFlip(List<Logic> addend, SignBit sign) → void
Helper function for sign extension routines: For signed operands, flip the MSB, otherwise add this sign bit.
inherited
getAbsolute(int row, int col) → Logic
Return the Logic at the absolute position (row, col).
inherited
getAbsoluteAll(int row, List<int> columns) → List<Logic>
Return the List at the absolute position (row, List columns.
inherited
insertAbsolute(int row, int col, Logic val) → void
Set a Logic val at the absolute position (row, col)
inherited
insertAbsoluteAll(int row, int col, List<Logic> list) → void
Set the values of the row, starting at absolute position (row, col) to the list of values
inherited
maxWidth() → int
Return the actual largest width of all rows
inherited
muxAbsolute(int row, int col, Logic condition, Logic val) → void
Mux the Logic at absolute position (row, col) conditionally by condition to val.
inherited
muxAbsoluteAll(int row, int col, Logic condition, List<Logic> list) → void
Mux the range of values into the row starting at absolute position (row, col) using condition to select the new value
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setAbsolute(int row, int col, Logic val) → void
Set the Logic at absolute position (row, col) to val.
inherited
setAbsoluteAll(int row, int col, List<Logic> list) → void
Set the range at absolute position (row, col) to list.
inherited
signExtend() → void
Perform sign extension (defined in child classes)
override
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
