Configurable AMBA On-Chip Real-Time Signal Tracer

This paper purpose an embedded AMBA signal tracer for microprocessor-based SoC's. This tracer provides five trace resolution modes that can perform a cycle-accurate or a transaction-based trace collection in an unlimited time. Also this tracer is implemented in a Soft-IP style. It provides four parameters for tracing configuration. The experimental results show that the bus tracer can reach a good compression ratio of 96%.
