Single Instruction Multiple Data processing using multiple banks of vector registers

摘要

A vector processor includes two banks of vector registers where each vector register can stored multiple data elements and a control register with a field indicating a default bank. An instruction set for the vector processor includes instructions which use a register number to identify a vector registers in the default bank, uses a register number to identify a double-size vector register including a register from the first bank and a register from the second bank, and instructions which include a bank bit and a register number to access a vector register from either bank.
