Abstract: A method for composing a multilayer video image of which the values of the pixels of the image layers are stored in a memory. The video image may include at least one first image layer and a second image layer located in front of the at least one first layer and having an opaque area. The method may include defining a region of the at least one first image layer to be hidden by the opaque area, reading from the memory the stored pixel values, with the exception of the values of the pixels of the region of the at least one first image layer, and composing the video image at least from the read pixel values.

Abstract: A method of verifying integrity of communications between a master circuit and a slave circuit includes updating a first cyclic multibit signature based on each transaction sent by the master circuit to the slave circuit. A second cyclic multibit signature is updated based on each transaction received by the slave circuit. One or more bits based on the second cyclic multibit signature are compared with corresponding bits based on the first cyclic multibit signature, with a number of the one or more bits being less than a total number of bits of the second cyclic signature. Error conditions are detected and responded based on the comparing.

Abstract: A system may include a first device, a second device, a third device, and a serial link between the second device and the third device. The first device may be configured to deliver to the second device an information stream having a transmission fault tolerance associated with a transmission by the second device to the third device over the serial link. A related method may include, during the transmission over the serial link, phases for synchronization between the second and third devices, and during each synchronization phase, the first device may continue to deliver the information stream to the second device.
