Project title is DDR3 Based Lookup Circuit for High Performance Network Processing. Nowadays, Double Data Rate (DDR) SDRAMs are very famous in the PC memory market. They are widely used for the networking systems. These memory devices have high density and high memory bandwidth. Their price is very less. Due to complex instruction-based memory access control and high-speed interface technology, a specific purpose memory controller is required for optimizing the memory access trade off. Here, we proposed a specific purpose DDR3 controller for high-performance table lookup and corresponding lookup circuit based on the Hash-CAM approach. In network equipment, Content Addressable Memory (CAM) based techniques is used for fast table look up. CAM technology is better than Random Access Memory (RAM) technology. Because, CAM based lookup circuit’s technology is having better performance, lower cost and higher memory density.
For securing the sensitive information, this Advanced Encryption Standard (AES) method is used. NIST (National Institute of Standards and Technology) has published this encryption method. Now this method is used all over the world to encrypt the information. AES will be used as the approved standard for a wide range of applications and will replace Data Encryption Standard (DES), which is old method.
Nowadays analysis of the high resolution satellite images is becoming an important research subject for analysis of urban areas. Automatic road network extraction is an important aspect of the urban analysis in the urban areas. We proposed two approaches to extract the road, they are Level Set and Mean Shift methods.
In cryptographic terminology, a message is referred as clear text or plain text. The process of hiding the contents of a message from unauthorized persons is called as Encryption. The encrypted message is referred as cipher text and only authorized persons can read the encrypted message. Decryption is a process of retrieving the plain text from the cipher text.

Nowadays performance of the microprocessor is improved rapidly. In contrast, bandwidths and memory latencies are less improved. The final result is, the system performance is limited by the memory access time. To solve this problem we designed and developed the Memory Controller (MC). The memory controller will control the memory of the system and it is integrated into the system chipset. It is a main part of the system. In this paper we explained how to develop an Advanced Micro controller Bus Architecture (AMBA) compliant MC as an Advanced High-performance Bus (AHB) slave.
