Abstract: A wireless display subsystem includes a hardware composition generator, a hardware video encoder, and a wireless hardware transport stream multiplexer. The hardware composition generator reads video data from a memory device and generates video frame data by synthesizing the video data. The hardware video encoder receives the video frame data in an on-the-fly (OTF) manner from the hardware composition generator and generates a video stream by encoding the video frame data. The wireless hardware transport stream multiplexer receives the video stream in the OTF manner from the hardware video encoder, reads an audio stream from the memory device, multiplexes the video stream and the audio stream, and generates a wireless display packet by packetizing the multiplexed video and audio streams.

Abstract: A semiconductor device includes a first processing unit configured to perform a calculation by using data stored in a memory; and a memory path controller configured to communicate with the first processing unit and control the memory for the first processing unit to perform the calculation, wherein the memory path controller includes an address region control unit configured to divide an address space of the memory to include a secure address and a non-secure address and permit the first processing unit to access the secure address or the non-secure address, and a first content firewall unit connected with the address region control unit and configured to prevent the first processing unit from writing secure contents in the non-secure address.
