1 / 54 page  2141D–HIREL–02/04 Features • 22.8 SPECint95 (estimated), 17SPECfp95 at 500 MHz (estimated) • 917MIPS at 500 MHz • Selectable Bus Clock (14 CPU Bus Dividers Up To 9x) • Seven Selectable Core-to-L2 Frequency Divisors • Selectable 603 Interface Voltage Below 3.3V (1.8V, 2.5V) • Selectable L2 interface of 1.8V or 2.5V • P D Typical 5.3W at 500 MHz, Full Operating Conditions • Nap, Doze and Sleep Modes for Power Saving • Superscalar (Four Instructions fetched per Clock Cycle) • 4 GB Direct Addressing Range • Virtual Memory: 4 hexabytes (252) • 64-bit Data and 32-bit Address Bus Interface • 32 KB Instruction and Data Cache • Eight Independent Execution Units and Three Register Files • Write-back and Write-through Operations • f INT Max = 450 MHz 500 MHz • f BUS Max = 133 MHz Description The PC7410 is the second microprocessor that uses the fourth (G4) full implementa- tion of the PowerPC ™ Reduced Instruction 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 protocol (4 MESI states plus a fifth state for shared intervention) and an implementation of the new AltiVec ™ technology instruc- tion set. New features have been developed to make latency equal for double-precision and single-precision floating-point operations involving multiplication. Additionally, in mem- ory 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. PowerPC 7410 RISC Microprocessor Product Specification PC7410 Rev. 2141D–HIREL–02/04 |
