4 CoreSight™ Address Translation Unit

The purpose of the css600_catu CoreSight Address Translation Unit (CATU) is to translate addresses between an AXI master and system memory.

The CATU is normally used along with the TMC to implement scattering of virtual trace buffers in physical memory.

The CATU translates contiguous Virtual Addresses (VAs) from an AXI master into non-contiguous Physical Addresses (PAs) that are intended for system memory.

The following figure shows the external connections on the CoreSight™ Address Translation Unit.
