The AMBA specification defines standards for on-chip communication in microcontrollers. It includes three bus standards: Advanced High-performance Bus (AHB) for high bandwidth communication, Advanced System Bus (ASB) and Advanced Peripheral Bus (APB) for lower bandwidth peripherals. The objectives are to facilitate right-first-time development, be technology independent, encourage modular design, and minimize infrastructure. A typical system has the CPU and memory on the high-performance AHB, with peripherals on the lower-bandwidth APB, connected via a bridge.

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous

Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.

afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed

This presentation is about Food Delivery Systems and how they are developed using the Software Development Life Cycle (SDLC) and other methods. It explains the steps involved in creating a food delivery app, from planning and designing to testing and launching. The slide also covers different tools and technologies used to make these systems work efficiently.
2. A protocol is a standardized set of rules for formatting and processing data. Protocols enable computers to
communicate with one another. The protocol is a set of rules on how communication happens between a
master and slave or a set of components.
These can be majorly divided into 2 categories:
1. On-chip communication protocols
2. 2. Peripheral communication protocols.
On-chip protocols are AXI, AHB, ASB, APB, OCP.
Peripheral protocols are PCIe, USB, SATA, UFS.
3. AMBAAHB is a bus interface suitable for high-performance synthesizable designs. It defines the interface between
components, such as Masters, interconnects, and Slaves. It supports multiple Bus Master, Burst
transfer, and pipelined operations.
Common AHB Slaves are internal memory devices, external memory interfaces, and high-bandwidth peripherals.
Some of the key features include Wide Data Bus Transfer, Single Clock Edge Operation, Burst Transfer, Pipelined
Transfer, and non-tristate implementation.

5. The APB protocol is a low-cost interface, optimized for minimal power consumption and reduced interface
complexity. The APB interface is not pipelined and is a sample, synchronous protocol. Every transfer takes at least
two cycles to complete.
The APB interface is designed for accessing the programmable control registers of peripheral devices. APB
peripherals are typically connected to the main memory system using an APB bridge.

7. The AHB to APB bridge is an AHB slave, providing an interface between the high-speed AHB and the low-
power APB. Read and write transfers on the AHB are converted into equivalent transfers on the APB. As the
APB is not pipelined, wait states are added during transfers to and from the APB when the AHB is required to
wait for the APB.
The APB bridge responds to transaction requests from the currently granted AHB master. The AHB transactions
are then converted into APB transactions.
• The AHB transactions with the HREADYout signal.
• The generation of all APB output signals.
The main sections of this module are:
• AHB slave bus interface.
• APB transfer state machine, which is independent of the device memory map.
• APB output signal generation.
