Firstly  the memory allocation of TMX320VC5409 is described and the its assembly line operation is analyzed. Secondly  the external program memory space memory structure and external data memory and program memory extension using skills are discussed. Finally  the IS61LV12816 is taken as an example to design the external memory expansion of the hardware and software. The practice has proved that the mode has great flexibility and practicality.

In this mode  the use of the current main stream single DSP + FPGA hardware architecture for image processing algorithms have already unable to meet the operational requirements of real-time. This paper proposed a new hardware architecture that is the three DSPs based on FPGA. With the traditional master-slave architectures is different  three DSP's external interfaces are connected with FPGA and other peripheral interfaces are connected to the FPGA. In the architecture  DSP is in the same position three and FPGA flow control for data management and other function to achieve. This connection has a strong restructuring and expansion  software development and more flexible. 2011 IEEE.   Central hole effect on Whispering-Gallery-Mode of triangular lattice photonic crystal microcavity (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Zhang Y.;  Wang L.;  Wang L.;  Wang L.;  Wang Z. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 Whispering-Gallery-Mode (WGM) photonic crystal microcavity is a kind of photonic crystal application and can potentially be used for miniaturized photonic devices  such as thresholdless lasers. In this paper we study the WGM of photonic crystal microcavities focusing on the so called H2 cavities which are formed by removing seven air holes. The WGM in these large-size cavities has some advantages compared with single defect WGM in the view of real device applications. We further add a central air hole in the cavity region to analyze the effect on WGM in the microcavity by finite difference time domain (FDTD) and plane wave expansion (PWE). It is found that the tolerance of WGM is large enough for the fabrication of electrical injection structure. 2008 SPIE.   Dipole mode photonic crystal point defect laser on ingaasp/inp 期刊论文  iSwitch采集 Journal of crystal growth, 2006, 卷号: 292, 期号: 2, 页码: 341-344 作者:  Zheng, W.
