Smaller, modern code base, use of COTS OSBi-Endian, commonly Big Endian for telecom sw stacks
Bit fields: MSB is 0 (LSB is 0 on Intel architecture)
Vector oriented instructions: Altivec to SSE2 tools provided by NA. Software
Instructions must be aligned on 4 byte boundaries (Intel architecture instructions vary in size, so do not require alignment)
Divide by zero returns zero (operation is fatal on Intel architecture)
Arguments are passed in registers stack (passed on stack for Intel architecture, passed on stack and registers for Intel® 64)
The bool data type is 4 bytes (1 byte on Intel architeccture)
