AS7263 − Detailed Description

4-Byte Floating-Point (FP) Registers

Several 4-byte registers (hex) are shown in the tables. Here is

an example of how the registers are used to represent floating

point data (based on the IEEE 754 standard):

Figure 30:

Example of the IEEE 754 Standard

The floating point (FP) value assumed by 32 bit binary32 data

with a biased exponent e (the 8 bit unsigned integer) and a 23

bit fraction is (for the above example).
