Material Architecture and organization of computerferoza rosalina
This document discusses the components and functions of a basic computer system. It lists five group members and then describes how the central processing unit (CPU), memory, and input/output devices work together. The CPU consists of a control unit and arithmetic logic unit (ALU) and follows a four-step machine cycle of fetch, decode, execute, and store to process instructions. The control unit directs this cycle and communicates with the ALU and memory, while the ALU performs arithmetic and logical operations.
Here are the steps to determine the status of the C, H, and Z flags after adding 0x38 and 0x2F:
1. 0x38 + 0x2F = 0x67
2. The addition does not generate a carry, so the C flag remains unset.
3. The addition results in a half carry, so the H flag is set.
4. The result 0x67 is non-zero, so the Z flag is unset.
Therefore, after adding 0x38 and 0x2F, the status flags would be:
C flag = 0
H flag = 1
Z flag = 0

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
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.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
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.

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

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
3. Aim Of the project is to design a 8-bit ALU which
accepts two 8-bit binary numbers and displays
results.
It performs arithmetical , logical and relational
operations.
ALU is designed by using of gates like
AND,OR,NAND,NOR,NOT,XOR and XNOR gates.
Verilog code is used for designing and EDA tool is
used for simulation.
4. An arithmetic logic unit (ALU) is a major
component of the central processing unit of a
computer system.
It does all processes related to arithmetic and
logic operations that need to be done on
instruction words.
In some microprocessor architectures, the ALU
is divided into the arithmetic unit (AU) and the
logic unit (LU).
5. Mathematician John von Neumann proposed the
ALU concept in 1945.
The first ALU was introduced in 1948 that
operated on single data bit.
In some early microprocessors employed a
narrow ALU which performs 32-bit operation in
two cycles with a 16-bit ALU.
Over time, transistor geometries shrank further
and it became feasible to build wider ALUs on
microprocessors.
18. The Arithmetic Logic Unit is an important part
of computer CPU’s. We learned how to produce
different arithmetic operations and logic
functions by using various select singles for a
single circuit.
The ALU can also be designed using reversible
logic gates instead of conventional gates.
The reversibility significantly reduces the use
and loss of information bits.
