【Abstract】 Matrix operation is one of the basic operations frequently used in the computer system, especially in the neural network system for pattern recognition. In this paper, the designing principle and related programming principle as well as a PC bus interface board of this operation in a hybrid neural network system for pattern recognition implemented with interface circuits are introduced. The experiment results show that, by employing this new kind of implementation, not only has the operation been speeded up, but also has the programs been simplified. As a result, matrix multiplication with 4K×4K bytes can be easily executed in a single operation. The principles of the design and the related skills will be generally applicable in all the systems where matrix operations are frequently needed.更多还原
