Single Chip DWT-IDWT Processor Design with VHDL

Architecture Design of a Scalable Single-Chip Multi-Processor

Now that system-on-chip technology is emerging, singlechip multi-processors are becoming feasible. A key problem of designing such systems is however the complexity of their interconnect and memory architecture [1]. An example of a single-chip multi-processor for real-time (embedded) systems is the Multi Micro Processor (M P). Its architecture consists of a scalable number of identical master p...

An optimized architecture for RPA-based direct DWT/IDWT computation

Abstract In this paper, we present an optimized architecture of RPA(Recursive Pyramid Algorithm) -based direct form for computing DWT/IDWT realtime. The architecture is based on the optimized DWT/IDWT computation, yielding about 70% reduction, and the pipelined and parallel computation, for high performance convolution up to 100fps, and the minimum datapath width of 9bits , to support at least ...

FPGA based DWT-IDWT implementation of OFDM on UWB Systems

Orthogonal Frequency Division Multiplexing/Modulation (OFDM) is widely used for symbol level modulationdemodulation in communication systems for a high data rate low distance range applications. OFDM refers to both multiplexing and modulation technique to transmit parallel data using orthogonal carriers in the same or different frequency bands. In this work, DWT-OFDM is modeled which aims to se...

Design of Multiplierless and High-Performance DWT and IDWT Architectures Using 4-tap Daubechies Filters

This paper proposes two architectures of 2-D discrete wavelet transform (DWT) and inverse DWT (IDWT). The first high-efficiency architecture comprises a transform module, an address sequencer, and a RAM module. The transform module has uniform and regular structure, simple control flow, and local communication. The significant advantages of the single transform module are full hardware-utilizat...
