Abstract
A row decoder (10) for a video display system (12) wherein row output lines (28) of a row predecoder (20) are physically arranged such that adjacent iterations of the output lines (28) will generally not be switching simultaneously where addressing of the output lines (28) is sequential according to numbering and application. A ground trace (32) is provided between iterations of the output lines (28) which will be switching simultaneously. The output lines (28) provide input to a decoding circuit (34) within the row decoder (10). A plurality iterations of predecoder subcircuits (21) each having a compliment of the output lines (28) is to provided such that all of the rows of a pixel array (14) can be addressed.
Claims15
A decoder device, comprising:
- a plurality of input lines for receiving data;
- a plurality of output data lines;
- and
- decoder logic operative to enable one of said output data lines depending on said data received on said input lines;
- and wherein
- responsive to a sequential stream of data being asserted on said input lines said output data lines are enabled in consecutive order, and wherein
- said output data lines are physically arranged in non-consecutive order.
