ABSTRACT:
In a program control type processor for executing plural instructions including a vector pipeline instruction including a data processor for executing a pipeline operation, there is provided a program controller including a program memory, a program counter and a decoder, and is further provided an address generator and a data memory. When the vector pipeline instruction is read out from the program memory and is decoded by the decoder, the program controller stops the program counter and outputs a start signal, and thereafter, controls an operation of the data processor according to the contents of the vector pipeline instruction. The data processor executes the pipeline operation for the data outputted from the data memory by being controlled by the program controller, and the program controller detects completion of the pipeline operation performed in response to the vector pipeline instruction a predetermined number of cycles after receiving the end signal, and thereafter, sequentially executes instructions following the vector pipeline instruction.
