1. A hardware device, comprising:
- an increment/decrement portion arranged to receive a modified clock signal and to linearly increment or decrement an intensity value toward a target intensity value, based on the modified clock signal; and
a divider portion arranged to receive a clock signal and a transition time value and to modify the clock signal based on the transition time value to produce the modified clock signal, the transition time value representing a time for the intensity value to transition from an initial intensity value to the target intensity value.

Abstract
Representative implementations of devices and techniques provide a linear walk arrangement for a control signal. A modified clock signal is used to increment or decrement a value of the control signal toward a target value. The modified clock signal is based on a specified transition time and a difference between an initial value for the control signal and the target value. Multiple control signals may be transitioned such that the control signals arrive at their respective target values simultaneously, notwithstanding the differences in transitions among the control signals.

9. A system implemented in hardware, comprising:
-
a first linear walk device arranged to linearly increment or decrement a first channel control signal value from a first initial value to a first target value at a first rate of change; and a second linear walk device arranged to linearly increment or decrement a second channel control signal value from a second initial value to a second target value at a second rate of change, such that the first channel control signal value arrives at the first target value and the second channel control signal value arrives at the second target value substantially simultaneously. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
