On the other hand, with the advancement of technology, the MoreSecure decryption algorithms are a type of cryptographic algorithms whose importance in today's society has been highlighted by applications such as the use of personal digital tools to maintain confidentiality. On the other hand, with the advancement of technology, the need to implement these algorithms on flexible platforms can be challenging. Reducing the area and speeding up the execution of operations are the main challenges for designing and implementing these algorithms. This paper proposes a new architecture for the FPGA-based processor for SHA-2 series cryptographic algorithms. In the proposed processor, the use of memory units and multi-port data path, followed by parallel processor performance, has reduced the use of resources and increased the speed of data processing. Processor architecture for SHA-2 cryptographic algorithms is modeled in VHDL and implemented on the FPGA platform in the Virtex series by ISE software. Implementation results show that the proposed compact processor compared to previous tasks with similar objectives, was able to increase the operating frequency for the SHA-256 cryptographic algorithm by 25% and occupy 55% less space for the SHA-512 cryptographic algorithm to the desired level of operational power and efficiency. Also maintain. The proposed processor is suitable for applications such as trusted mobile platforms (TMP), digital currency (Bitcoin) and secure on-chip network routing (NoC). Manuscript profile -

M V Ganeswara Rao P Ravi Kumar T BalajiA dual stage system architecture for face detection based on skin tone detection and Viola and Jones face detection structure is presented in this paper. The proposed architecture able to track down human faces in the image with high accuracy within time constrain. A no MoreA dual stage system architecture for face detection based on skin tone detection and Viola and Jones face detection structure is presented in this paper. The proposed architecture able to track down human faces in the image with high accuracy within time constrain. A non-linear transformation technique is introduced in the first stage to reduce the false alarms in second stage. Moreover, in the second stage pipe line technique is used to improve overall throughput of the system. The proposed system design is based on Xil¬inx’s Virtex FPGA chip and Texas Instruments DSP processor. The dual port BRAM memory in FPGA chip and EMIF (External Memory Interface) of DSP processor are used as interface between FPGA and DSP processor. The proposed system exploits advantages of both the computational elements (FPGA and DSP) and the system level pipelining to achieve real time perform¬ance. The present system implementation focuses on high accurate and high speed face detec¬tion and this system evaluated using standard BAO image database, which include images with different poses, orientations, occlusions and illumination. The proposed system attained 16.53 FPS frame rate for the input image spatial resolution of 640X480, which is 23.4 times faster detection of faces compared to MATLAB implementation and 12.14 times faster than DSP implementation and 2.1 times faster than FPGA implementation.
