VLIW architecture optimization for an efficient computation of stereoscopic video applications

Abstract: This paper presents two new architecture optimiza tions to improve the processing performance of video applications with a high degree of data parallelism in VLIW processors. On the one hand, a new register file access mechanism, called X4 operation mode, allows to access wide operands made up of several consecutive registers in the register file, while keeping its normal functionality (i.e. single read/write register access). On the other hand, a new functional unit is proposed to efficiently process a typica… Show more

“…Two internal 16x64-bit RF are used, hence single 64-bit accesses can be performed to all the positions of both RFs by using the 64 LSB of each port. Aligned (even positions) 128-bit accesses can also be performed [9].…”

“…The above presented VLIW-SIMD architecture has already been evaluated in the context of video processing [9]. By using its X2/X4 instruction merging mechanisms (code up to four operations into one instruction) and custom functional units it became possible to process a stereo video algorithm under real-time conditions, resulting in very high computational efficiency.…”
