Implementation of AMBA AHB Bus Arbiter using Amalgamate Algorithm

On Chip Bus Architecture play a very important role in SOC system. Now days there are many on chip bus architecture are provided by different company. One of the most popular is advance microcontroller bus architecture which is popularly known as AMBA 1.0. AMBA have an advantage that it is open specification i.e. AMBA serve as a framework for system on chip design. In System On chip, problem arises when number of master trying to sense a single data bus. Then resolutions of a required become a big issue. The overall system performance depends upon the ability of system to resolve this resolution problem. The AMBA protocol use logical assignment of chance to different masters according to their priority to take over the bus for data transmission. AMBA architecture defines three specifications. They are advance high performance bus (AHB), advance peripheral bus (APB) and advance system bus (ASB). Among all three specification AHB have high bandwidth and this make AHB as first choice for system designer. While resolving the problem of priority resolution, arbiter plays an important role. Arbiter is a digital circuit and it working is depends upon the arbitration algorithm used. According to arbitration algorithm, arbiter decides to give grant to heights priority master to access bus. In this project we design arbitration algorithm, according to it arbiter give grant to different masters.
