摘要:
A method and device for programming an array of individually controllable elements configured to impart a beam with a pattern. For example, the method can be suitable for use in a lithographic apparatus. The method comprises generating first data representing a first pattern, generating second data representing a second pattern, writing the first data to a first buffer, and reading the first data from the first buffer to program the array of individually controllable elements to display the first pattern, while writing the second data to a second buffer in parallel.
