An Improved MDCT IP Core Generator with Architectural Model Simulation

Compression of digital audio signals has become very important audio computation process. When audio data are compressed it is possible to store more data in a smaller memory and to increase the overall audio data throughput transferred through an interface. Several compression schemes were developed and well established. Most of them adopt the MDCT/IMDCT. This paper presents an software tool, an improved MDCT IP core generator with architectural model simulation that is capable to generate several MDCT architectures with adjustable parameters for FPGA-based design. The software tool has integrated functions of the computation precision and area estimation, which facilitate and speed up the design process.
