| Abstract: | Concerning the challenges on performance, power, area of Arithmetic Logical Unit (ALU) and shifter in DSP CPU, this paper studied the architecture of X DSP and analyzed the characteristics of all instructions related to ALU unit, and shifter unit and designed and implemented the two units. This paper also synthesized the two computational units by using design compiler with SMIC 0.13μm CMOS technology library. The total circuit power consumption was 4.2821mW, the area of the circuit was 71042.9804μm2,and the frequency was 250MHz, which met the requirements of the system. |
