Abstract: A data processing system (DPS) uses platform protection technology (PPT) to protect some or all of the code and data belonging to certain software modules. The PPT may include a virtual machine monitor (VMM) to enable an untrusted application and a trusted application to run on top of a single operating system (OS), while preventing the untrusted application from accessing memory used by the trusted application. The VMM may use a first extended page table (EPT) to translate a guest physical address (GPA) into a first host physical address (HPA) for the untrusted application. The VMM may use a second EPT to translate the GPA into a second HPA for the trusted application. The first and second EPTs may map the same GPA to different HPAs. Other embodiments are described and claimed.

Abstract: The invention enables mapping inputs to a software application. The invention comprises (i) receiving a keymap that correlates a first set of input events capable of being generated through an input device, with a second set of input events that are recognizable by the software application, (ii) receiving from the input device, a first data signal associated with a first input event within the first set of input events, (iii) identifying based on the received keymap, a second input event within the second set of input events, wherein the second input event is mapped to the first input event by the received keymap, (iv) generating a second data signal, wherein the second data signal is recognizable by the software application as corresponding to the second input event, and (v) implementing a state change in the software application based on the second data signal.

Abstract: A hardware profiling mechanism implemented by performance monitoring hardware enables page level automatic binary translation. The hardware during runtime identifies a code page in memory containing potentially optimizable instructions. The hardware requests allocation of a new page in memory associated with the code page, where the new page contains a collection of counters and each of the counters corresponds to one of the instructions in the code page. When the hardware detects a branch instruction having a branch target within the code page, it increments one of the counters that has the same position in the new page as the branch target in the code page. The execution of the code page is repeated and the counters are incremented when branch targets fall within the code page. The hardware then provides the counter values in the new page to a binary translator for binary translation.

Abstract: A method and apparatus for providing reliable data communications over an unreliable voice dispatch communications channel is provided. A voice dispatch channel is established between an originating mobile station (102) and a target mobile station (104). The voice communications channel uses a Push-to-view reliability protocol that utilizes real time protocol data packets (500) and real time control protocol control messages (600) to provide the reliable data communications. Data is sent from the originating mobile station to the target mobile station using the RTP data packets. When the target mobile station determines that it is missing data or that the data is corrupted, it sends a negative acknowledge to the originating mobile station using RTCP control messages.

Abstract: A system includes a first wireless device (102) and a second wireless device (106), each having at least two communication modes—one for voice transmission and reception and one for data transmission and reception, and able to communicate wirelessly with each other. The system also includes a shared object between the two devices. During an ongoing conversation between a user of the first device (102) and a user of the second device (106), an object is exchanged between the devices. The devices, working within available manipulation capabilities, communicate manipulation instructions to one another on the data mode of communication. The instructions are carried out and the object is manipulated, providing a shared interactive quasi-real-time or real-time experience.
