The present disclosure relates to ADC data processing circuitry for touch controllers. According to one embodiment, a signal processing circuit includes a coefficient accumulator and a dual multiplexer path for processing invalid ADC samples in a touch controller. When an ADC sample exceeds a saturation threshold, the circuit selects a zero value through one multiplexer while accumulating a coefficient through the other multiplexer path. Upon receiving a first valid sample, the circuit multiplies it with the accumulated coefficient and then resumes normal coefficient processing. This architecture enables continuous processing across multiple touch sensor channels without the need for buffering while maintaining mathematical equivalence through multiplication distribution rates.

Disclosed are predecoders and structures including the predecoders. Each predecoder includes, among other components, first and second latches controlled by write and read clock signals, respectively, and a multiplexer-enabled write logic bypass path. During a write, an address signal is latched by the first latch and propagated through logic downstream of the first latch (including through a write logic block) to the second latch (which is transparent).

In both operations, a predecoded address signal is output but, due to activation of the write logic bypass path during the read, the time between receiving the address signal and outputting the predecoded address signal is reduced.
