Processor
The MVME5500 supports the MPC7455 processor in the 483-pin CBGA
package. The processor consists of a processor core, an internal 256KB L2
and an internal L3 tag and controller, which supports a backside L3 cache.
L3 Cache
The MVME5500 uses two 8Mb DDR synchronous SRAM devices for the
processor’s L3 cache data SRAM. This gives the processor a total of 2MB
of L3 cache. These SRAM devices require a 2.5V core voltage. The
