Abstract
Examples include a fluidic die. The fluidic die may comprise an array of fluid actuators, an actuation data register, a mask register, and actuation logic. The actuation data register may store actuation data that indicates fluid ejectors to actuate for a set of actuation events. The mask register may store mask data that indicates a set of fluid actuators enabled for actuation for a respective actuation event of the set of actuation events. The actuation logic may electrically actuate a subset of the fluid actuators based at least in part on the actuation data register and the mask register for the respective actuation event.
Claims15
A fluidic die comprising:
- an array of fluid actuators;
- an actuation data register to store actuation data that indicates each fluid actuator to actuate for a set of actuation events;
- a mask register to store mask data that indicates a set of fluid actuators of the array of fluid actuators enabled for actuation for a respective actuation event of the set of actuation events;
- and
- actuation logic coupled to the actuation data register, the mask register, and the respective fluid actuators, the actuation logic to electrically actuate a subset of the fluid actuators based at least in part on the actuation data register and the mask register for the respective actuation event,
- wherein the fluidic die includes the array of fluid actuators, the actuation data register, the mask register and the actuation logic.
A fluidic die comprising:
- an array of fluid actuators;
- an actuation data register including a respective actuation bit for each respective fluid actuator of the array of fluid actuators, the respective actuation bit indicating whether to actuate the respective fluid actuator for a set of actuation events;
- a mask register to store mask data, the mask register including a respective mask bit for each respective fluid actuator of the array of fluid actuators, the respective mask bit indicating whether the respective fluid actuator is enabled for actuation for a respective actuation event of the set of actuation events;
- and
- actuation logic coupled to the actuation data register, the mask register, and the array of fluid actuators, the actuation logic to actuate fluid actuators of the array based at least in part on the respective actuation bit and the respective mask bit for each respective fluid actuator for the respective actuation event,
- wherein the fluidic die includes the array of fluid actuators, the actuation data register, the mask register and the actuation logic.
A method for a fluidic die comprising:
- actuating fluid actuators of an array of fluid actuators for a first actuation event of a set of actuation events based at least in part on actuation data stored in an actuation register of the fluidic die and based at least in part on mask data stored in a mask register of the fluidic die, the actuation data indicating each respective fluid actuator of the array to actuate for the set of actuation events, and the mask data indicating a first subset of respective fluid actuators of the array enabled for actuation for the first actuation event;
- and
- responsive to actuating the fluid actuators for the first actuation event, shifting the mask data of the mask register to indicate a second subset of respective fluid actuators of the array enabled for actuation for a second actuation event of the set of actuation events,
- wherein the fluidic die includes the array of fluid actuators, the actuation data register, the mask register and the actuation logic.
