<p>A data processing system containing a vector processor (30) and a scalar processor (15) executes scalar and vector instructions which both comprise an operation portion and an operand pointer portion. In the vector instructions, however, the operand pointer portion contains an operand specifier (154, 155, 156, 157, 158) which identifies a vector control word (160). Each vector control word (160) contains, for the corresponding vector instruction, flags (162) and vector operand pointers. The vector operand pointers specify vector registers in the vector processor. The flags (162) contain additional information for the execution of the vector instructions.</p> |
