| Abstract | ||
| Wavelet Packet Transform (WPT) is an effective tool for analyzing signals used in different practical applications especially in speech and image processing fields. This paper introduces a design of a wavelet packet transform system configured on field programmable Gate arrays (FPGAs) slice using embedded design techniques. The hardware part is constituted by configuring a Microblaze soft core processor system on Spartan 3e FPGAs slice. The floating point unit available in the Microblaze processor is enabled to make the system deal with 32 bits floating point numbers as well as integers. A DDR-SDRAM with 64 Mbytes capacity is added to the hardware to accommodate with the signals containing high frequency components, like image signals, that implies large number of samples. The embedded processor system is programmed by a C language application program to make the system act as a wavelet packet transform system. Xilinx ISE10.1 software was utilized to develop the hardware and software parts of the designed embedded system. System performance is tested for seven levels decomposition of an audio signal with satisfactory results obtained compared with the results achieved by Matlab 7.2 version software. | ||
