摘要：
This invention provides trace address compression by comparing respective bytes of a current trace address with a stored comparison address. Only the least significant bytes of the current trace address that do not match the comparison address or are less significant than any section of the current trace address that does not match the comparison address are transmitted. This sometimes reduces the amount of data that needs to be transmitted. The comparison address is specified by a central processing unit via a memory mapped register write operation.
