在 0 .1 8μm工艺或更小的线宽下 ,可把各单个子系统有效地集成在同一块芯片上。通过讨论新工艺条件下具有语音视频图像处理功能的高速编码正交频分复用调制 (OFDM)集成系统设计的可能方案 ,并剖析实例 ,对其离散余弦变换、快速傅里叶变换及前向纠错编码进行了分析。
In the 0 .1 8μm process or smaller line width, the individual subsystems can be effectively integrated on the same chip. By discussing the possible schemes of high-speed coding Orthogonal Frequency Division Multiplexing (OFDM) integrated system with speech and video image processing under the new process conditions and analyzing examples, the discrete cosine transform, fast Fourier transform and forward Error correction coding was analyzed.
