MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Advanced Microcontroller Bus Architecture (AMBA) is a freely available, open standard for the connection and management of functional blocks in a System-on-Chip (SoC). The architecture facilitates right-first-time development of multi-processor designs, with large numbers of controllers and peripherals.

Detailed explanation-2: -The ARM Advanced Microcontroller Bus Architecture (AMBA) is an open-standard, on-chip interconnect specification for the connection and management of functional blocks in system-on-a-chip (SoC) designs.

Detailed explanation-3: -AMBA ASB is an alternative system bus suitable for use where the high-performance features of AHB are not required. ASB also supports the efficient connection of processors, on-chip memories and off-chip external memory interfaces with low-power peripheral macrocell functions.

Detailed explanation-4: -The ASB is a high-performance pipelined bus, which supports multiple bus masters. The basic flow of the bus operation is: The arbiter determines which master is granted access to the bus. When granted, a master initiates transfers on the bus.

Detailed explanation-5: -The ASB is a simplified version of the AHB and offers high performance for 16-and 32-bit systems. Many of the same signals on an AHB are used for the ASB aside from certain control signals that allow for split transactions. The operation of the ASB starts with a master requesting access to the bus from the arbiter.
