The document discusses the 8255 programmable parallel I/O device that can be used to interface I/O devices to a microprocessor like the 8085. It describes how the 8255 has three I/O ports (Port A, Port B, Port C) that can be configured using a control word. It then provides an example of interfacing an 8-bit analog to digital converter and temperature sensor to the 8255 ports to read temperature values using instructions like OUT, IN.

Describes ARM7-TDMI Processor Instruction Set. Explains classes of ARM7 instructions, syntax of data processing instructions, branch instructions, load-store instructions, coprocessor instructions, thumb state instructions.
The System Verilog UVM promises to improve verification productivity while enabling teams to share tests and test benches between projects and divisions. This promise can be achieved; the UVM is a powerful methodology for using constrained randomization to reach higher functional coverage goals and to explore combinations of tests without having to write each one individually. Unfortunately the UVM promise can be hard to reach without training, practice and some significant expertise. Verification is one of the most important activities in the flow of ASIC/VLSI design. Verification consumes large amount of design flow cycle & efforts to ensure design is bug free. Hence it becomes intense requirement for powerful and reusable methodology for verification.
this ppt only for beginner who want to understand concept of Timer counter operation of LPC2148 step by step.
hope it may help u.
always welcoming ur suggestion.

*Analog to digital conversion
*Digital to Analog conversion
An analog-to-digital converter (ADC, A/D, or A to D) is a device that converts a continuous physical quantity (usually voltage) to a digital number that represents the quantity's amplitude.
The conversion involves quantization of the input, so it necessarily introduces a small amount of error. Instead of doing a single conversion, an ADC often performs the conversions ("samples" the input) periodically. The result is a sequence of digital values that have been converted from a continuous-time and continuous-amplitude analog signal to a discrete-time and discrete-amplitude digital signal.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
