In this paper we shall propose and examine an VLSI architecture for the integer-to-integer wavelet transform which is used by JPEG2000 standard for lossless compression. In order to achieve a fully utilization of hardware resources independently of the bit-depth of the input data, on-line arithmetic (digit-serial computation) is proposed to carry out this architecture. Besides, a high throughput is achieved thanks to the high degree of parallelism that on-line arithmetic allows. The design has been simulated and implemented using Xilinx FPGA device, and its main results are provided.
