The SPEAR300-2 internal architecture is based on several shared subsystem logic blocks interconnected through a multilayer interconnection matrix. The switch matrix structure allows different subsystem dataflow to be executed in parallel improving the core platform efficiency. High-performance master agents are directly interconnected with the memory controller reducing the memory access latency. The overall memory bandwidth assigned to each master port can be programmed and optimized through an internally efficient weighted round-robin arbitration mechanism.
