CHAPTER 1 INTRODUCTION

1.5.4 Data Formats and Addressing
The VR4102 uses following four data formats:
Doubleword (64 bits)
Word (32 bits)
Halfword (16 bits)
Byte (8 bits)
For the VR4100 CPU core, byte ordering within all of the larger data formats - halfword, word, doubleword - can
be configured in either big-endian or little-endian order. However, the VR4102 supports the little-endian order
only.
Endianness refers to the location of byte 0 within the multi-byte data structure. Figure 1-5 shows the ordering of
bytes within words and the ordering of words within doubleword structures for the little-endian conventions.
When configured as a little-endian system, byte 0 is always the least-significant (rightmost) byte, which is
compatible with iAPXTM and DEC VAXTM conventions. Figure 1-5 shows this configuration.

Remarks 1. The lowest byte is the lowest address.
2. The address of word data is specified by the lowest byte’s address.
In this manual, bit 0 is always the least-significant (rightmost) bit; thus, bit designations are always little-endian.
Figure 1-6 shows little-endian byte ordering in doublewords.
