摘要： Methods and apparatus for synchronizing multiple virtual processors of a virtual machine are disclosed. A hypervisor schedules a first virtual processor in a virtual machine to execute using a first physical processor. Subsequently, the hypervisor receives an indication from the first virtual processor that it is waiting on a second different virtual processor. If the second virtual processor is not already running on another physical processor, the hypervisor saves the priority associated with the first virtual processor, lowers the priority associated with the first virtual processor, and schedules the second virtual processor to execute using the first physical processor or another physical processor.

Each of the input interface (62), first processor (64), second processor (66), and output interface (68) computes a digest (92, 100, 110, and 114) using information, e.g., a unique parameter (94, 102, 112, 118), known only by that element (62, 64, 66, 68) and using information generated by that element (62, 64, 66, 68). The digests (92, 100, 110, and 114) are used to validate the integrity of payload data (86) processed by the system (60) to form processed data (104) and the system (60) only outputs the processed data (104) upon validation of data integrity. The serial configuration of system (60) may be implemented to provide high bit rate, redundant cryptographic services.

摘要： Embodiments include methods for determining synchronization/pilot sequences (SPS) to be utilized in conjunction with transmissions by antennas of a multiple-antenna transmitter. The SPS include pilot signals that are positioned at subcarriers that are orthogonal in frequency with subcarriers at which pilot signals of other antennas are positioned. The pilot signals may be unevenly spaced across the in-band subcarriers. The multiple-antenna transmit system generates a plurality of wireless signals, each of which may include an SPS having synchronization information in a first plurality of in-band subcarriers and the pilot signals in a second plurality of in-band subcarriers. The wireless signals are simultaneously radiated over a wireless communication channel using a different antenna. A receiver receives channel-affected versions of the wireless signals, and produces a corrected signal by applying corrections to the received signal based on estimated channel perturbations within the received signal.
