It features five I/O ports, three timers, USART serial communication, and 15 interrupt sources. Instructions are in RISC format and execute in 4 machine cycles, with most instructions completing in one cycle.
Clock distribution
This document discusses clock distribution networks in integrated circuits. It describes how clock generators produce timing signals to synchronize a system's operation using resonant circuits and amplifiers. As process technologies allow for higher integration and larger die sizes, clock networks must support higher frequencies while minimizing skew and jitter. Various clock distribution topologies are presented, including unconstrained trees, balanced trees, central spines, grids, and hybrid distributions, each with advantages and disadvantages depending on the design.

It provides examples of how always blocks, variables assignments, if/else statements, case statements, mathematical operations, counters and other code are mapped to logic gates, flip-flops and other digital circuits.
Synchronous and asynchronous clock
The document discusses synchronous and asynchronous clocks. A clock is a square wave signal generated by an oscillator that provides two levels, high and low. Clocks are used to time signals in circuits to avoid glitches, which are unpredictable outputs caused by differences in propagation delays. There are two types of clocks: synchronous clocks have the same phase but frequencies may differ, while asynchronous clocks have different phases and frequencies may also differ. Asynchronous clocks can cause glitches, so synchronization is needed to make clocks operate synchronously.
Implementing Useful Clock Skew Using Skew Groups
Implementing useful skew through skew groups or manual buffer insertion can improve timing in a large memory block design. Skew groups define a target skew value for groups of clock pins before clock tree synthesis, resulting in a smaller clock tree, lower power increase, and less routing complexity compared to manual buffer insertion. Manual insertion precisely controls skew by adding buffers but dramatically increases clock cell count and power consumption versus skew groups. Both methods effectively improved setup timing for the memory block design.

Counters are widely used in computers and devices like clocks to keep track of events.
Clock Distribution

Introduction to pll
1. The document introduces phase locked loops (PLLs), which are electronic circuits that lock the phase of the output signal to the phase of the input signal.
2. A basic PLL system consists of a phase detector that detects the phase difference between the input and output signals, a low pass filter, and a voltage controlled oscillator whose frequency is adjusted based on the output of the filter to reduce the phase difference.
3. Modern PLLs often use a phase/frequency detector and a charge pump instead of just a phase detector, which allows the loop to lock faster and be more stable. Charge pump PLLs work by using the phase/frequency detector to control switches that charge or discharge a capacitor, producing the control voltage
Sram technology
SRAM is used as cache memory interfacing between DRAM and the CPU due to its faster access speeds compared to DRAM. It is also used in low power applications where DRAM refresh currents would be too high. The SRAM cell consists of a bi-stable flip-flop connected to internal circuitry by two access transistors. To read or write data, the word line is activated, connecting the flip-flop to bit lines and sense amplifiers. The data is volatile but does not need refresh like DRAM as it does not leak over time. Different SRAM cell designs use either 4 transistors plus resistive loads or 6 transistors.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
