Using the example value of −γ = 7.50373 × 10−5 yields  
Calculation of the β Register Values  
The quantized β coefficient consists of two components, β0 and  
β1, according to  
x = 13, so γ1 = 13  
y = 80570.6873700352, so γ0 = 80571  
−β ≈ βquantized = β0 × 2−(17 + β )  
1
This leads to the following quantized value, which is very close  
to the desired value of 7.50373 × 10−5:  
where β0 and β1 are the register values.  
Calculation of β1 is a two-step process that leads to the  
calculation of β0, which is also a two-step process.  
γquantized = 80571 × 2−30 ≈ 7.503759116 × 10−5  
Calculation of the δ Register Values  
x = −ceil(log2( ))  
β
The quantized δ coefficient consists of two components, δ0 and  
δ1, according to  
β1 = min[31, max(0, x)]  
δ ≈ δquantized = δ0 × 2−(15 + δ )  
y = round( × 217 + β  
)

β
where δ0 and δ1 are the register values.  
β0 = min[131071, max(1, y)]  
Using the example value of −β = 6.98672 × 10−5 yields  
Calculation of δ1 is a two-step process that leads to the  
calculation of δ0, which is also a two-step process.  
x = 13, so β1 = 13  
x = −ceil(log2(δ))  
y = 75019.3347657728, so β0 = 75019  
δ1 = min[31, max(0, x)]  
This leads to the following quantized value, which is very close  
to the desired value of 6.98672 × 10−5:  
y = round(δ × 215 + δ  
)

quantized = 75019 × 2−30 ≈ 6.986688823 × 10−5  
Using the example value of δ = 0.002015399, the preceding  
formulas yield  
Calculation of the γ Register Values  
The quantized γ coefficient consists of two components, γ0 and  
γ1, according to  
x = 8, so δ1 = 8  
−γ ≈ γquantized = γ0 × 2−(17 + γ )  
y = 16906.392174592, so δ0 = 16906

This leads to the following quantized value, which is very close  
to the desired value of 0.002015399:  
where γ0 and γ1 are the register values.  
Calculation of γ1 is a two-step process that leads to the  
calculation of γ0, which is also a two-step process.  
δquantized = 16906 × 2−23 ≈ 0.002015352249  
x = −ceil(log2( γ ))  
y1 = min[31, max(0, x)]  
y = round( γ × 217 + γ  
)
