Fixed-Point Operator Replacement

Define code replacement mappings for fixed-point operations

Use the Code Replacement Tool or programming interface to define code replacement mappings for fixed-point operations, including shift left operations and different types of scaling — for example, binary point or net slope.

Topics

Fixed-Point Operator Code Replacement

Define code replacement mappings for fixed-point operators.

Binary-Point-Only Scaling Code Replacement

Define code replacement mappings for operations on fixed-point data types so that they match a binary-point-only scaling combination on operator inputs and output.

Slope Bias Scaling Code Replacement

Define code replacement mappings for operations on fixed-point data types as matching a slope bias scaling combination on the operator inputs and output.

Net Slope Scaling Code Replacement

Define a code replacement mapping for operations on fixed-point data types as matching net slope between operator inputs and output.

Equal Slope and Zero Net Bias Code Replacement

Define code replacement mappings for addition and subtraction of fixed-point data types so that they match relative slope and bias values (equal slope and zero net bias) across operator inputs and output.

Data Type Conversions (Casts) and Operator Code Replacement

Define code replacement mappings for code that the code generator produces for data type conversion (cast) operations.

Shift Left Operations and Code Replacement

Define code replacement mappings for code that the code generator produces for shift (<<) operations.
