Benchmarking 4x ARM Cortex-A7 CPU and 4x ARM Cortex-A53 for multimedia systems using JPEG compression

Abstract

More advancement has been observed in the design and development of multimedia based embedded systems in recent years. As a result of such advancements, new development boards and techniques are being released very frequently. This paper presents a comparison of two state of the art processors of AMD (Advanced Micro Devices). The two RISC (Reduced Instruction Set Computer) architecture based processors are 4x ARM (Advanced RISC Machine) Cortex-A7 CPU (Central Processing Unit) and 4x ARM Cortex-A53. These two processors have been used in Raspberry Pi 2 and Raspberry Pi 3, respectively. The comparison of these two processors, in terms of their suitability for compressed visual multimedia information has been carried out by implementing JPEG (Joint Photographic Experts Group) compression, and calculating the execution time of different modules of the algorithm. The results suggest that 4x ARM Cortex-A53 provides better results in JPEG compression than 4x ARM Cortex-A7 CPU.
