Application-Specic Information
PowerPC 603e RISC Microprocessor Family:
MPC603r (Goldeneye) Part Number Specication
This document denes a unique part number for a PowerPC PID7t-603e microprocessor manufactured by Motorola as part number MPC603R or EC603R. It describes changes to recommended operating conditions and revised electrical specications, as applicable, from those described in the PowerPC 603e RISC Microprocessor Family: MPC603r Hardware Specications. Specications provided in this data sheet supercede those in the MPC603r Hardware Specications (order #: MPC603REC/D); specications not addressed herein are unchanged. Note that headings and tables in this data sheet are not numbered; however, they are intended to correspond directly to the heading or table affected in the general hardware specications. Any additional information (including tables) not included in the hardware specication are noted. Part numbers addressed in this document and a summary of their differences from the general specication are listed in the following table. For more detailed ordering infomation see OOrdering Information for the PID7t-603e Microprocessor".

This section summarizes signicant feature changes between the revision of the PID7t-603e addressed by this document and the previous revision 1.0 (XPC603RRXnnnLA or XPC603RFEnnnLA where nnn is the core frequency). This revision was for manufacturing improvements only; there are no functional differences between this revision 2.1 and the previous revision 1.0. This revision is functionally equivalent to the PID7v-603e (Valiant) microprocessor Revision 2.1 (XPC603PFEnnnLE/ XPC603PRXnnnLE) including the following errata.
Errata
This section summarizes design defects or errors (errata) that are known to exist on this revision of the PID7t-603e. There may be additional errata that are not known or are not yet documented here which may cause the part to deviate from the functional description provided in the MPC603e & EC603e RISC Microprocessor UserOs Manual (order # MPC603EUM/AD Rev 1). Refer to the website at http://www.mot.com/SPS/PowerPC/ for the latest version of this Part Number Specication or to your local Motorola sales ofce for later and/or more detailed description of the errata.

Feature Changes
The known errata as of the date of this document are summarized below.
# 1
Problem Snoop copyback causes dcbi to broadcast wrong address.
Description A snoop which causes a copyback and occurs in a one cycle window near a dcbi causes the dcbi to broadcast the address of the snoop copyback. The problem occurs when two processors are competing on the bus for a reservation, and the bus is operating with address pipelining A touch load (dcbt) preceded by an instruction that generates an exception causes a random address to appear on the memory bus The sequence of write-thru stores followed by dcbz followed by a snoop, all to the same cache line, may cause incoherency.
Impact Only systems using both software and hardware coherency simultaneously.
Solutions Use software semaphores rather than rely on dcbi to invalidate cache lines shared across multiple processors.
2
Competition for reservation with lwarx/stwcx may cause live-lock
System Hang
Insert a bus clockOs worth of no-ops before lwarx
3
Touch load causes incorrect address to appear on memory bus
Systems issuing instructions which generate mmu exceptions one cycle before using a touch load instruction
Disable touch loads with NOOPTI bit in HID0.
4
Write-thru stores followed by dcbz followed by a snoop, all to the same cache line, may cause incoherency.
The write-thru store is completed after the dcbz.
Store zeroes rather than rely on dcbz to zero cache lines in areas of memory that are marked as write-thru and can be accessed via multiple logical addresses. Disable broadcasting of dcbz by marking the memory space being addressed by the dcbz instruction as not global in the BAT or PTE.
5
The broadcasting of dcbz instructions may retry snoop accesses indenately.
A sequence of broadcast bcbz instructions may retry snoop accesses indenately.
Snoop originator may timeout.
