This invention discloses a VLIW with single-instruction multiple data streams converging computing cluster structure, which includes the data buffer and microcontroller connected with main controller, and their connective computing cluster. The main controller are responsible for the instruction and data mobile, instruction loads in the microcontroller, data loads in the data buffer and receives their output. The data buffer receives main controller data, supplies operation data for computing cluster and receives its result, and outputs to the main controller. Microcontroller receives the VLIW sequence form main controller, decodes and broadcast to each processing unit for parallel execution. The computing group includes a number of same processing units with a number of dealing components respectively and the same instruction sequence, and the data is from different modules of data buffer.

The invention relates to the multimedia data communication technology field and provides a multimedia data safety monitoring device, a receiving terminal, a multimedia data authentication method and a system thereof. The authentication system comprises: a multimedia data safety monitoring device and a multimedia data receiving terminal, wherein the multimedia data safety monitoring device is used to acquire multimedia data, carry out safety authentication to the multimedia data and stores authentication result information in a safety checking code database; the multimedia data receiving terminal is used to receive the multimedia data, using a same method which the multimedia data safety monitoring device used to carry out the safety authentication to the multimedia data and feed back the safety authentication result information to the multimedia data safety monitoring device. The multimedia data safety monitoring device carries out comparison authentication to the received safety authentication result information and the corresponding safety authentication result information stored in the safety checking code database. If the two are matched, the authentication is passed and the multimedia data receiving terminal decodes and plays. A technical scheme is easy to be realized. Contents are safe and a definition is simple and strictness. Security is high. Implementation and management costs are low.
