Description
The PC7410 is the second microprocessor that uses the fourth (G4) full implementation of the PowerPC Reduced Instruc-
tion Set Computer (RISC) architecture. It is fully JTAG-compliant.
The PC7410 maintains some of the characteristics of G3 microprocessors:
• The design is superscalar, capable of issuing three instructions per clock cycle into eight independent execution units
• The microprocessor provides four software controllable power-saving modes and a thermal assist unit management
• The microprocessor has separate 32-Kbyte, physically-addressed instruction and data caches with dedicated L2 cache
interface with on-chip L2 tags
In addition, the PC7410 integrates full hardware-based multiprocessing capability, including a 5-state cache coherency pro-
tocol (4 MESI states plus a fifth state for shared intervention) and an implementation of the new AltiVec^® technology
instruction set.
New features have been developed to make latency equal for double-precision and single-precision floating-point opera-
tions involving multiplication. Additionally, in memory subsystem (MSS) bandwidth, the PC7410 offers an optional, high-
bandwidth MPX bus interface.
Unlike the PC7400, the PC7410 does not support the 3.3V I/O on the L2 cache interface.
