The execution time overhead of software emulation is reduced by selecting frequently emulated instruction sequences in the software being emulated, and translating those instruction sequences into the instruction set of the emulating processor. In a first phase, frequently repeated sequences of emulated computer code are identified and selected for translation. In a second phase, the selected sequences from the instruction set of the emulated processor are translated into equivalent sequences for the instruction set of the emulating processor. In a third phase, the instruction sequence of the emulating processor is executed in lieu of emulating the original instructions from the emulated software.

Morphing techniques are employed to enable a user to locally deform a texture image on a three-dimensional object, and thereby align image features in a texture map with geometric features of the object. An affine transformation can be applied to the texture map to provide a rough fit of the texture image to the geometric model. The transformed texture image is placed on the geometric model and the user designates corresponding features on the texture image and the geometric model. Once the designations have been completed, the texture image is warped into a final, deformed image, which is then mapped onto the three-dimensional object. With this approach, the user can apply pre-existing images to three-dimensional models, without being requ...

In a system for describing directional sounds in virtual environments, a user creates a sound projection map that constitutes a two-dimensional array of sound intensities for each sound source associated with the virtual environment. At run-time, when a user selects a particular view for a scene in the environment, a hearing area corresponding to that view is calculated. The average intensity for each sound represented within the hearing area is determined from the array, to establish a level at which the sound is to be played. The sound associated with the sound source is then reproduced from a sound track at the determined level, to produce an output sound that creates a sense of place within the environment.

The present invention is a system for inexpensive phase coherent subcarrier generation. In the implementation of the present invention, it is recognized that the subcarrier sequence has a fairly short periodicity (two lines), allowing a relatively short lookup table to hold coded values precisely representing the sampled subcarrier. A variety of modulation techniques may be employed to minimize the error between the reconstructed subcarrier sine wave and an "ideal" subcarrier sine wave. The SCH phase may be easily varied by using a different table of subcarrier sine wave values.

Signal transactions are conducted between nodes coupled to a bus, without causing bus deadlock during split transactions. Deadlock avoidance is achieved by rendering a node effectively unavailable at such times to serve as a bus slave for a new bus master. When the "locking" node serves as a transaction source, deadlock is avoided by deasserting, during a split transaction, a buffer-available signal, which is used normally to indicate receiver buffer availability. Additionally, when the "locking" node serves as a transaction destination, deadlock is avoided by deasserting a bus-ownership request signal, which is used normally for requesting bus ownership. After completion of the split transactions, such signals may be unmasked.

To optimize sytem bus utilization in a computer system, a bus coordinator is included in the computer system to coordinate the transfer of information signals on the bus. Each time a source node wishes to transfer information to a destination node, the source node sends a request to the coordinator along with the identification of the destination node. Upon receiving this request, the coordinator determines whether the destination node has capacity to receive information signals. If the destination node has capacity, then the coordinator grants control of the system bus to the source node to allow the source node to send information signals to the destination node via the system bus. Otherwise, the source node is denied control of the syste...

A system for pipelining bus requests includes a bus, at least one node coupled to the bus, and a bus coordinator coupled to the node. The node uses a single bus request signal to both request control of the bus from the bus coordinator, and to retain control of the bus. In response to an asserted bus request signal from the node, the coordinator sends an asserted bus grant signal to the node to grant the node control of the bus. This bus grant signal tracks the bus request signal so that as long as the bus request signal remains asserted, the bus grant signal also is asserted. To allow for pipelining, the bus coordinator maintains the bus grant signal in an asserted state for at least one clock cycle after the bus request is deasserted. By ...
