ABSTRACT

Microprocessor performance has improved rapidly these years. In contrast memory latencies and bandwidths have improved little. The result is that the memory access time is the bottleneck which limits the system performance. In case of larger system design which requires more number of I/O ports and more memory capacity the system designer may interface external I/O ports and memory with the system. In this paper we are using advanced microcontroller bus architecture with its advanced high performance bus. AMBA AHB provides parallel communications with multi master bus management, high clock frequency, high performance systems for data transfer operation from the memory interfaced with the master or slave peripheral devices. AMBA AHB supports on chip communications standard for designing high-performance embedded microcontrollers.
