Implementation of AMBA AHB Protocol for Wide Narrow BUS-SLAVE Combination Using VHDL
The Advanced Microcontroller Bus Architecture (AMBA) is an open System-on-Chip bus protocol for high-performance buses on low-power devices. In this paper, the authors implement a simple model of AMBA and use model checking and theorem proving to verify latency, arbitration, coherence and deadlock freedom properties of the implementation. Typical microprocessor and memory verifications assume direct connections between processors, peripherals and memory, and zero latency data transfers. They abstract away the data transfer infrastructure as it is not relevant to the verification. However, this infrastructure is in itself quite complex and worthy of formal verification. The Advanced Microcontroller Bus Architecture1 (AMBA) is an open System-on-Chip bus protocol for high-performance buses on low-power devices.
