The Military

With the rapid development of electronic science and computer science, the large scale integrated circuit applied in the military, economic and social life is more and more widely. Because the DDR SDRAM has twice the SDRAM memory data rate, now has been widely used. The DDR memory controller design for the DDR SDRAM and the connection between the FPGA provides a solution [3]. This paper analyzes the current international technology trends and storage controller DDR2 SDRAM controller detailed technical specifications. DDR2 SDRAM controller configuration based on register information units, with automatic initialization, to determine priorities, to generate the DDR2 command sequence, and other functions, also can undertake signal control and data reading and writing.

Sdram Controller

Separate software is hard to achieve real-time HD decoding for its sequential execution, while pure hardware is unable to complete the complex AVS video decoding. Aiming at this, this paper adopts the SoC scheme to develop the controller in AVS decoder. The author selected the OpenRISC1200 processor for its no licensing fees and completely open source. For AVS decoder’s high-complexity, we reconfigured the core to optimize it and designed some peripherals - SDRAM controller, VGA controller, and Wishbone bus module. By elaborating the module’s design, simulation, synthesis, static timing analysis and formal verification, this paper proposes a solution of high-speed & high integration controller in AVS-SoC decoder chip. This controller can quickly complete the AVS stream parsing and system controlling, and also it can improve the AVS chip’s integration and the versatility. Overall, it has great application value and broad market prospects.

This paper presents a new design of omnidirectional automatic guided vehicle based on a hub motor, and proposes a joint controller for path tracking. The proposed controller includes two parts: a fuzzy controller and a multi-step predictive optimal controller. Firstly, based on various steering conditions, the kinematics model of the whole vehicle and the pose (position, angle) model in the global coordinate system are introduced. Secondly, based on the modeling, the joint controller is designed. Lateral deviation and course deviation are used as the input variables of the control system, and the threshold value is switched according to the value of the input variable to realise the correction of the large range of posture deviation. Finally, the joint controller is implemented by using the industrial PC and the self-developed control system based on the Freescale minimum system. Path tracking experiments were made under the straight and circular paths to test the ability of the joint controller for reducing the pose deviation. The experimental results show that the designed guided vehicle has excellent ability to path tracking, which meets the design goals.
