The e500 core connects to the L2 cache and the system interface through the high-speed core complex bus

(CCB). The e500 core and the L2 cache connect to the rest of the integrated device through the e500

coherency module (ECM).

e500 core can simultaneously read 128 bits of data from the L2/SRAM, read 64 bits of data from the

system interface, and write 128 bits of data to the L2/SRAM and/or system interface.
