Abstract :
An 81.6 GOPS object recognition processor based on memory-centric NoC (MC-NoC) is implemented in a 0.18-mum CMOS technology. The MC-NoC facilitates data transactions among 10 SIMD processing elements (PEs) by exploiting 8 visual image processing (VIP) memories. The 10 PEs implement special SIMD instructions to perform Gaussian filtering at 16 GOPS. The 8 VIP memories provide one cycle local maximum pixels search operation performing 65.6 GOPS. The chip dissipates 1.4 W at 200 MHz operating frequency.
