The purpose of this paper is to present how to implement Segment_LCD display using SoC design. The SoC design is achieved by using an ARM_based Excalibur device. The Excalibur device offers an outstanding embedded development platform with ARM922T and FPA. The design in the Excailbur device uses the embedded AR띤 Processor core and the AMBA high-performance bus (AHH) to write to a memory-mapped slave peripheral in the FPGA portion of the device. Here, Segment_LCD is one kind of memory-mapped slave peripherals. In order to Implement the Segment_LCD display based on SoC design, four steps are fellowed. At first, IP modules are made by using Verilog HDL. Secondly, the ARM processor of the Excalibur is programmed using C in ADS (ARM Developer Suite). And in the third step, the whole system is simulated and verified. At last, modules are downloaded to SoCMaster kit. Both Quartus II software and ModelSim5.5e software are the key software tools during the design.

In this paper, we propose an IP design and implementation of System on a chip(SoC) for Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) processor using adder-based DA(Adder-based Distributed Arithmetic). To reduced hardware cost and to improve operating speed, the combined DCT/ DWT processor used the bit-serial method and DA module. The transform of coefficient equation result in reduction in hardware cost and has a regularity in implementation. We use Verilog-HDL and Xilinx ISE for simulation and implement FPGA on SoCMaster-3.

In this paper, we present a multi-core processor including multimedia specific instructions to process multimedia data efficiently in the mobile environment. Multimedia specific instructions exploit subword level parallelism (SLP), while the multi-core processor exploits data level parallelism (DLP). These combined parallelisms improve the performance of multimedia processing applications. The proposed multi-core processor including multimedia specific instructions is implemented and tested using a Xilinx ISE 10.1 tool and SoCMaster3 testbed system including Vertex 4 FPGA. Experimental results using a fire detection algorithm show that multimedia specific instructions outperform baseline instructions in the same multi-core architecture in terms of performance (1.2x better), energy efficiency (1.37x better), and area efficiency (1.23x better).
