hwtLib.mem.atomic.flipCntr.
FlipCntr
[source]¶Bases: hwt.synthesizer.unit.Unit
Counter with FlipRegister which is form memory with atomic access
interface doFilip drives switching of memories in flip register dataIn has higher priority than doIncr
_config
()[source]¶Configure object parameters
_declr
()[source]¶declarations
_serializeDecision
(parentUnit, obj, isDeclaration, priv)¶Decide to serialize only first obj of it’s class
Parameters: | priv – private data for this function (first object with class == obj.__class__) |
---|---|
Returns: | tuple (do serialize this object, next priv) where priv is private data for this function (first object with class == obj.__class__) |
hwtLib.mem.atomic.flipRam.
FlipRam
[source]¶Bases: hwt.synthesizer.unit.Unit
Switchable RAM, there are two memories and two sets of ports, Each set of ports is every time connected to opposite ram. By select you can choose between RAMs.
This component is meant to be form of synchronization. Example first RAM is connected to first set of ports, writer performs actualizations on first RAM and reader reads data from second ram by second set of ports.
Then select is set and access is flipped. Reader now has access to RAM 0 and writer to RAM 1.

_serializeDecision
(parentUnit, obj, isDeclaration, priv)¶Decide to serialize only objs with uniq parameters and class
Parameters: | priv – private data for this function ({frozen_params: obj}) |
---|---|
Returns: | tuple (do serialize this object, next priv) |
hwtLib.mem.atomic.flipReg.
FlipRegister
[source]¶Bases: hwt.synthesizer.unit.Unit
Switchable register, there are two registers and two sets of ports, Each set of ports is every time connected to opposite reg. By select you can choose between regs.
This component is meant to be form of synchronization. Example first reg is connected to first set of ports, writer performs actualizations on first reg and reader reads data from second ram by second set of ports.
Then select is set and access is flipped. Reader now has access to reg 0 and writer to reg 1.
