The Green Droid mobile application processor prototype targets the Android mobile software stack. It uses specialized energy-efficient cores called conservation cores (c-cores) to execute frequently used portions of application code, accounting for 95% of execution time. The c-cores reduce energy consumption by 56% by removing unnecessary structures like instruction fetch and decode units. Additional 35% savings comes from specializing the c-core data path. This allows average per-instruction energy to drop from 91 pJ to just 8 pJ. The Green Droid is estimated to reduce processor energy consumption by 91% for targeted code and provide an overall 7.4x energy savings.
The document discusses the GreenDroid mobile application processor, which uses specialized "conservation cores" (c-cores) to execute frequently used portions of application code and reduce energy consumption by 11x compared to conventional designs. It achieves this by filling the "dark silicon" areas of chips with these automatically generated c-cores. The c-cores are highly efficient because they remove unnecessary structures like instruction decoding. This approach converts unused silicon into significant energy savings while maintaining performance.

This document summarizes a seminar on digital signatures. It defines a digital signature as an encrypted hash value of a message that is unique to the document and verifies the identity of the owner. Digital signatures provide authenticity, integrity, and non-repudiation for electronic documents. The technology uses public and private key pairs, with the private key used to generate signatures and the public key used to verify signatures. Some challenges of digital signatures include the cost of certification authorities and ensuring private keys remain secure, but they enable secure e-commerce, e-governance and other applications.
Digital signatures provide authentication and integrity for electronic documents and transactions. They use public key cryptography where a document is encrypted with the sender's private key and decrypted by the recipient's public key. A digital certificate issued by a certificate authority binds the signer's identity to their public key and is verified using the CA's digital signature. Common uses of digital signatures include software updates, financial transactions, and legally binding documents.
This document provides an introduction to digital signatures, including an overview of encryption, hashing, digital signature creation and verification, and different digital signature schemes like RSA, ElGamal, and Schnorr. It also discusses the legal aspects and advantages/disadvantages of digital signatures.
This document provides an overview of the GreenDroid mobile application processor prototype. GreenDroid targets the Android mobile software stack and aims to execute general mobile programs with 11 times less energy than current designs, through the use of 100+ automatically generated specialized cores called conservation cores (c-cores). C-cores are designed to reduce energy consumption by targeting specific Android hotspots. The GreenDroid architecture uses an array of tiles, each containing a CPU, cache, and 8-15 c-cores. C-cores handle frequently executed hotspot code while less common cold code runs on the CPU. This approach aims to maximize silicon utilization in the face of the growing dark silicon problem caused by the utilization wall effect from Moore's Law scaling
Li-Fi is a wireless communication technology that uses visible light communication (VLC) to transmit data using LED light bulbs. By switching LED bulbs on and off faster than the human eye can detect, digital data can be encoded and transmitted through the light. Li-Fi provides several advantages over traditional Wi-Fi including much higher speeds, no interference with other wireless devices, and the ability to be used in places where radio signals are restricted. Researchers have achieved speeds over 500 megabytes per second in labs. Li-Fi has the potential to help solve the worldwide shortage of wireless spectrum and enable new applications for wireless connectivity through light.
