Changeset 247 for trunk/platforms/tsarv4_mono_mmu

Timestamp:

Message:

Introducing new CLEANUP transaction address specification in the components:

• vci_cc_vcache_wrapper_v4
• vci_mem_cache_v4

The new specification uses the VCI WDATA and the VCI BE to send the cleanup
nline. The VCI ADDRESS is like follows:

• NLINE MSb | Memory Cache local ID | 00....00

The platforms:

• tsarv4_mono_mmu
• tsarv4_generic_mmu

has been modified to use the modified components and the mapping table for the coherence
address space has been updated.

File:

• trunk/platforms/tsarv4_mono_mmu/top.cpp (modified) (4 diffs)
