Multicore platform-orientated asymmetrical dispatcher for monitor of virtual machine and dispatching method thereof

The invention discloses an asymmetrical dispatcher for a multicore platform-orientated asymmetrical dispatcher for a monitor of a virtual machine and a dispatching method thereof, which provides a specialized service core meeting the special high performance demand is provided for a client operation system based on the conventional virtual machine monitor VMM. The dispatcher comprises a service core request resolution module in a management domain, a Domain specific service core configuration module in VMM, a system top dispatcher module, a service dispatcher module, a shared memory mechanism module and a request inquiry module, and a hybrid virtual module in an HVM Domain. The asymmetrical dispatcher in the invention not only can provide different service cores according to the demands of upper layer Domain, but also can provide higher flexibility and expandability than the traditional dispatcher due to the consideration of the topological structure of a physical platform during the distribution of the service cores. In addition, the dispatcher provides an acceleration mechanism of a specific application type for the client operation system and improves the service efficiency of the entire platform.

Medium reinforced pipelined multiplication unit design method supporting multiple mode

The invention discloses a multi-mode supported media reinforcement flowline multiplication unit design method. Besides realizing the common multiplication and the multiplication progression operations, the invention also provides the single instruction multiple data (SIMD) mode aiming at the data parallelism in the media application, the multiple-instruction multiple data (SDMD) mode aiming at the non data parallelism in the media application and the high accuracy operation mode aiming at the high accuracy data operation. The four multiplication operation modes provide the support for the complex algorithm of the digital signal processing in the media application field. The four modes can be dynamically switched by instructions, thereby effectively reducing the time of the algorithm switch. The multiplication unit applies flowline design methods respectively aiming at different multiplications, thereby improving the operation speed of all multiplications and greatly enhancing the operation efficiency. When the multiplication unit provided by the invention is applied to an embedding type processor, the digital signal processing capability of the embedding type processor is improved and the application domain is widened.
