PowerPC Microprocessor
The main logic board supports the third generation (G3) PowerPC 750 series of microprocessors running at 233 MHz, 266 MHz, 300 MHz, and 333 MHz. Apple refers to these processors as PowerPC G3 microprocessors.
The principal features of the PowerPC G3 microprocessor include
-
full RISC processing architecture
-
parallel processing units: load-store unit, two integer units, one complex integer unit, and one floating-point unit
-
a branch manager that can usually implement branches by reloading the incoming instruction queue without using any processing time
-
integrated L2 cache controller and Tag RAMs for high performance memory access
-
an internal memory management unit (MMU)
-
64 KB of on-chip cache memory (32 KB each for data and instructions)
For complete technical details, see the Motorola PowerPC Library web page at http://www.mot.com/SPS/PowerPC/library/library.html.
The PowerPC G3 is located on a plug-in microprocessor card module which includes the L2 cache.
