Abstract
A 32-bit RISC processor is disclosed. The bit length of the instruction set is fixed to 16 bits. SLIL and SLIH instructions that cause the address space of 4 Gbytes to be limited to upper 2 Mbytes and that execute a long type register branch instruction are provided. Thus, a register branch instruction can be executed with three instructions rather than five instructions unlike with a related art reference.
