The 604e implements the PowerPC architecture as it is specified for 32-bit addressing, which provides 32-bit effective (logical) addresses, integer data types of 8, 16, and 32 bits, and floating-point data types of 32 and 64 bits (single-precision and double-precision). (...) The 604e has a 64-bit external data bus and a 32-bit address bus.
