    摘要: Provided is a parallel processor for supporting a floating-point operation. The parallel processor has a flexible structure for easy development of a parallel algorithm involving multimedia computing, requires low hardware cost, and consumes low power. To support floating-point operations, the parallel processor uses floating-point accumulators and a flag for floating-point multiplication. Using the parallel processor, it is possible to process a geometric transformation operation in a 3-dimensional (3D) graphics process at low cost. Also, the cost of a bus width for instructions can be minimized by a partitioned Single-Instruction Multiple-Data (SIMD) method and a method of conditionally executing instructions.

    摘要: A multiple-single instruction multiple data (SIMD) processor and an arithmetic method using the same are disclosed. When various arithmetic operations should be individually carried out by SIMD arithmetic units, control right is sub-divided to perform the arithmetic operations, such that the time of the arithmetic operations can be shortened and the efficiency thereof can be raised. When sub-divided control is not required, the control right is withdrawn and the arithmetic operations are carried out using a minimum number of program memories and a minimum number of SIMD arithmetic units, such that memory and power consumption thereof can be reduced.
