ABSTRACT:
A microprocessor includes a first ringed shift register having a plurality of registers storing a plurality of context information respectively, the registers being connected in a loop, an instruction decoder transmitting the context information to a reference register in the first ringed shift register, an instruction execution unit exchanging the context information with the reference register, and a control unit controlling the first ringed shift register to perform a shift operation to carry out context switching.
