What is the use of AMBA bus in ARM?
The Advanced Micro controller Bus Architecture (AMBA) bus protocols is a set of interconnect specifications from ARM that standardizes on chip communication mechanisms between various functional blocks (or IP) for building high performance SOC designs.
What does AHB bus stand for?
AHB stands for Advanced High-performance Bus and APB sands for Advanced Peripheral Bus. Both the Advanced High-performance Bus and the Advanced Peripheral Bus are part of the Advanced Microprocessor Bus Architecture (AMBA). The APB is mainly proposed for connecting to simple peripherals.
What is AHB bus in stm32?
AHB (Advanced High-performance Bus) APB ( Advanced Peripheral Bus)
Why do we use AHB?
It is a simple non-pipelined protocol that can be used to communicate(read or write) from a bridge/master to a number of slaves through the shared bus. The reads and writes shares the same set of signals and no burst data transfers are supported. AHB-lite protocol is a simplified version of AHB.
What is AMBA in embedded system?
AMBA (Advanced Microcontroller Bus Architecture) is a freely-available, open standard for the connection and management of functional blocks in a system-on-chip (SoC). It facilitates right-first-time development of multi-processor designs, with large numbers of controllers and peripherals.
What AMBA means?
Amba is a Sanskrit word meaning “mother.” It is also one of the more popular names of the Hindu goddess Druga, particularly in western India. In the “Mahabharata,” the epic Hindu poem, Amba is the eldest of three daughters of the king of Kashi.
What is the use of the AMBA interface?
What is the use of AHB protocol?
AMBA AHB is a bus interface suitable for high-performance synthesizable designs. It defines the interface between components, such as masters, interconnects, and slaves. AMBA AHB implements the features required for high-performance, high clock frequency systems including: • Burst transfers.
What is the difference between AHB and Amba?
Answer Wiki. The Advanced Micro controller Bus Architecture (AMBA) specification defines an onchip communications standard for building high performance SOC designs. AHB: The Advanced High-performance Bus (AHB) is used to connect components that need higher bandwidth. These could be a internal memory or an external memory interface, DMA etc.
What are the different bus types used in amba2?
AMBA 2 specification defines three buses/interfaces: Advanced High-performance Bus (AHB) – widely used on ARM7, ARM9 and ARM Cortex-M based designs Advanced System Bus (ASB) Advanced Peripheral Bus (APB2 or APB)
What is the history of AMBA bus?
AMBA is a registered trademark of ARM Ltd. AMBA was introduced by ARM in 1996. The first AMBA buses were Advanced System Bus (ASB) and Advanced Peripheral Bus (APB). In its second version, AMBA 2 in 1999, ARM added AMBA High-performance Bus (AHB) that is a single clock-edge protocol.
What is Amba (Advanced Micro controller bus architecture)?
The Advanced Micro controller Bus Architecture ( AMBA) specification defines an onchip communications standard for building high performance SOC designs. AHB: The Advanced High-performance Bus (AHB) is used to connect components that need higher bandwidth.
