The embodiments of the present application provide a processing unit. The processing unit comprises: an instruction fetching unit configured for fusing instruction of vector configuration instruction and vector operation instruction that are adjacent in order to obtain fusion instruction; an instruction decoding unit configured to decode the fusion instruction to obtain first execution information and second execution information; a vector configuration unit configured to execute the vector configuration instruction according to the first execution information, modify vector control register, and bypass the value of the modified vector control register to the vector operation unit; the vector operation unit configured to execute the vector operation instruction according to the second execution information and the value of the modified vector control register.

Computing device and method for fusing and executing vector instructions

A processor achieving a zero-overhead loop, includes instruction stream control circuitry and loop control circuitry. The loop control circuitry includes loop address detecting circuitry and loop end determining circuitry. By combining instructions and hardware, the loop control circuitry eliminates additional control instructions required b each loop iteration and can achieve loop acceleration with zero overhead, thereby improving the loop execution efficiency.
