Clock gating is an effective method of reducing the dynamic power consumption in synchronous circuits.
One of the ways to achieve this is by masking the clock that goes to the idle portion of the circuit. In This paper
we will present a comparative analysis of existing clock gating techniques on some synchronous digital design
like ALU (Arithmetic logical unit) etc. Also a new clock gating technique that provides more immunity to the
existing problem in available technique. In new proposed clock gating the Gated Clock Generation Circuit is using
tri state buffer and Gated logic is used which is created by the combination of double gated (AND, OR, AND
logic gate) with bubbled input respectively. This circuit saves power even when Target device's clock is ON. All
experiments are done on Xilinx14.1 EDA tool. Mentor Graphics Model SIM. For power calculation we are using
XPOWER. Sparten-3 (90nm) FPGA platform is used for result and analysis. The proposed design will reduce the
hardware complexity with approximately 10-20%. Similar clock power complexity will reduce with 5-10%.

• combine 8-stages of the CLA adder to create the 32-bit CSA

Analysis of Power Optimization of Serial Communication Protocol-Memory–Switch...IJRES Journal
Power consumption has rapidly risen to an intolerable scale. This results in both high operating costs and high failure rates so it is now a major cause for concern. It is imposed new challenges to the development of high performance systems. Dynamic power can contribute up to 50% of the total power dissipation.In this paper; we first review the basic power management techniques to reduce the dynamic power consumption techniques like clock gating & frequency scaling. Clock-gating is the most common RTL optimization for reducing dynamic power. We have been also studied I2C and SPI are the most commonly used serial protocols for both inter-chip and intra-chip low/medium bandwidth data-transfers. Both protocols are well suited for communications between integrated circuits for slow communication with on-board peripherals.
During the presentation, speaker told about common problems faced by software developers, provided examples of engineering errors and their costs, suggested ways of avoiding errors in the development, and covered the following topics:
- architecture and Impact Analysis;
- why developers write tests;
- cost of testing and ways to reduce it.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
