Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

Abstract: Embodiments of a bridge circuit and system are disclosed that may allow converting transactions from one communication protocol to another. The bridge circuit may be coupled to a first bus employing a first communication protocol, and a second bus employing a second communication protocol. The second bus may include a plurality of virtual channels. The bridge circuit may be configured to receive transactions over the first bus, and convert the transactions to the second communication protocol, and to assign the converted transaction to one of the plurality of virtual channels. The bridge circuit may be further configured store the converted transaction. A plurality of limited throughput signals may be generated by the bridge circuit dependent upon a number of available credits for the plurality of virtual channels.
