Implementation of multi-slave interface for AXI bus

With the need of application, chip with a single processor can't meet the need of more and more complex computational task. We are able to integrate multiple processors on a chip. Multi Procesor System on Chip (MPSoC) which gives a solution to this requires efficient on-chip communication architectures to support high data bandwidth and increase parallelism. However, traditional buses only allow one master to access one slave at one time, which badly restricts the performance of the whole system. In this paper we focus on the design and implementation of a multi slave interface for AXI bus, which translates data in burst, maximal length of which is up to 16 transactions. Besides, it only needs to translate the head address of the burst in this transaction. Owing to that feature, multiple masters accessing multiple slaves at one time becomes possible in sharing address bus architecture.
