摘要: 反量化、反变换 (IQIT) 是H.264解码过程中的重要环节之一.文中根据H.264规范, 设计了一种节省资源的IQIT模块.通过对其中矩阵运算单元进行多次复用, 大大降低了对资源的占用, 并通过FPGA进行了验证.该设计结构能够满足低功耗、便携式解码设备要求.Abstract: IQIT is an important process in H.264 decoding.In this paper, a resource efficient structure compliant with H.264 standard is presented.By multiplexing the IDCT module in different ways, the consumed resource was extremely reduced.This structure is verified on FPGA and is suitable for low-power and portable decoding device.
