Advanced Microcontroller Bus Architecture (AMBA)
Definition - What does Advanced Microcontroller Bus Architecture (AMBA) mean?
Advanced microcontroller bus architecture (AMBA) is an architecture that is widely used in system-on-chip designs, which are found on chip buses. The AMBA specification standard is used for designing high-level embedded microcontrollers. AMBA’s major objective is to provide technology independence and to encourage modular system design. Furthermore, it strongly encourages the development of reusable peripheral devices while minimizing silicon infrastructure.
Techopedia explains Advanced Microcontroller Bus Architecture (AMBA)
AMBA is an open specification that specifies a strategy on the management of the functional blocks that sort system on chip (SoC) architecture. It is a high-speed, high-bandwidth bus that supports multimaster bus management to get the most out of system performance. AMBA specifications are able to maximize the use of system bus bandwidth during dead time. After defining a common backbone for SoC modules, it enhances a reusable design methodology. This system has emerged as the defacto standard for IP library progress and SoC interconnection.
Five interfaces are defined within the AMBA specification:
- Advanced system bus (ASB)
- Advanced peripheral bus (APB)
- Advanced high-performance bus (AHB)
- Advanced extensible interface (AXI)
- Advanced trace bus (ATB)
