Description: 这是06年4月刚刚完成的程序，从opencore.org下载而来。用vhdl语言描写，以及matlab仿真，testbench，以及在xinlinx上的综合。
The MDCT core is two dimensional discrete cosine transform implementation designed for use in compression systems like JPEG. Architecture is based on parallel distributed arithmetic with butterfly computation.
-This is April 06 had just completed the process, from opencore.org downloaded from. Vhdl description language used, and Matlab simulation, testbench, and the Comprehensive xinlinx. The MDCT core is two dimensional discrete cosin e transform implementation designed for use in JPEG compression systems like. Architecture i 's based on parallel distributed arithmetic wit h butterfly computation. Platform: |
