A parametric DCT macro cell generator with a simulation model and an accuracy report

We developed a soft macro cell generator which generates discrete cosine transform (DCT) macro cells for various video compression requirements. Because of the proposed fast algorithm, hardware implementation, and customized flip flop cells, a generated macro cell is as small as any other full custom DCT LSI and macro cell, although the generator's output is a soft macro cell. Furthermore an equivalent C language model and an accuracy report necessary for parameter optimization of complex DCT arithmetic are also generated. An MPEG-quality DCT macro cell has been generated and fabricated on 0.7 /spl mu/m 3-metal CMOS for performance evaluation, such as cell speed, size, and design time.
