SIMD architectures, comprising of both scalar and parallel units, have been widely used in media processors. To further improve the performance, much effort has been made to enhance the design of both units, while little attention has been placed on the relationship between the units. This paper demonstrates that a dynamic coupling mechanism, which can dynamically transform the scalar and parallel...
To further improve the performance of SIMD (Single Instruction Multiple Data) architectures, which are widely used in the wireless communication domain. The main components of Long Term Evolution (LTE) protocol are analyzed. Performance investigation is taken on a cycle-accurate simulator, featuring the main characteristics of existing SIMD architectures. Based on the investigation, three insightful...
Hybrid architectures combined of VLIW, SIMD and multi-core schemes are increasingly prevailing in media processors, due to the abundant parallelism existed in media applications. However, parameters for current combinations such as the VLIW length, SIMD width and core count are set mainly according to simple profiling or the designer's experience rather than a systematic and in-depth investigation...
