Instruction Addresses Near Canonical Address Limit May Cause Gp Exception - AMD 3200 - Athlon 64 2.0 GHz Processor Manual

Revision Guide for AMD Family h Models h- Fh Processors Rev October
Instruction Addresses Near Canonical Address Limit May
Cause GP Exception
Description
The processor may incorrectly generate a GP exception when an instruction executes within a small window of
the linear-memory address at the limit of canonical address space FFF FFFF FFFFh
FFF FFFF FFF h and multiple branch mis-predicts occur to a linear-memory address at the limit of
canonical address space
Potential Effect on System
In the unlikely event that the conditions for this erratum occur an unexpected GP exception may result in a
program or system crash
Suggested Workaround
None required
Fix Planned
Yes
