The operand data formats supported by the integer unit are standard
two’s-complement data formats. The operand size for each instruction is
either explicitly encoded in the instruction (load/store instructions) or
implicitly defined by the instruction operation (index operations, byte
extraction). Typically, instructions operate on all 32 bits of the source
operand(s) and generate a 32-bit result.
Memory is viewed from a big-endian byte ordering perspective. The
most significant byte (byte 0) of word 0 is located at address 0. Bits are
numbered within a word starting with bit 31 as the most significant bit.
