当前的ＶＬＳＩ数字信号处理器都以乘加器为运算单元，去完成各种正交变换，常会遇到稳定性问题。该文提出了一类新型的以快速旋转器为运算核的ＶＬＳＩ变换微处理器，它能以最佳的数值稳定性高效地完成用Ｇｉｖｅｎｓ旋转序列实现的各种正交变换。结合图像处理应用的实际需要，设计了包含三个并行的ＴＦＥ变换机的ＰＴＦＥ试验芯片，采用０．８μｍ双层金属ＣＭＯＳ工艺制造，测试表明，功能正确，工作频率达到４０ＭＨｚ，具有高达９６０×１０６ｓ－１移加的运算吞吐率。芯片具有高度的灵活性、可编程性和可扩展性。与该芯片配合，开发了一个针对图像处理中常用变换、按照ＰＴＦＥ硬件控制信号格式产生指令序列的编译器。
The current VLSI digital signal processors multiply adders for the computing unit to complete a variety of orthogonal transformation, often encounter stability problems. In this paper, a new type of VLSI transform microprocessor based on fast rotator is presented, which can perform various orthogonal transformations with Givens rotation sequence with the best numerical stability. According to the actual needs of image processing application, a PTFE test chip with three parallel TFE converters was designed and fabricated by 0.8μm double-layer metal CMOS process. The test shows that the function is correct, the operating frequency is up to 40MHz and the up to 960 × 106s -1 Increasing operation throughput. The chip has a high degree of flexibility, programmability and scalability. In conjunction with this chip, a compiler was developed for common transforms in image processing and instruction sequences generated in accordance with the PTFE hardware control signal format.
