Updating Build Configuration

Navigate to Configuration Parameters > Code Generation > Build Configuration and select Faster Builds to compile your code with higher optimization, effectively reducing run-time.

Toolchain Selection

The Texas Instruments C2000 processors are supported by various toolchain options, enabling the users to generate executable files in different formats. The supported toolchains for c28x core include:

Based on the processor selection, multiple toolchain options are supported. Choosing the appropriate toolchain can also impact performance. For more information, see Exploring TI C2000 Toolchain Options.

Data Type Optimization.  Select the appropriate data type, single or double, based on the precision required by your FPU type processor. Additionally, examine the signal data types and use the minimum required precision whenever possible. For example, if the variable Counter can range from 0 to 130, a 16-bit integer data type would be sufficient instead of using double or single. For more information, see Exploring TI C2000 Toolchain Options.

Enable Code Replacement Library (CRL)

Ensure optimal hardware functions by selecting TI C28x in Configuration Parameters > Code Generation > Interface > Code replacement library. This replaces functions like multiplication, additions, IQMath operations, Fast integer division, CLA math operations and more for EABI toolchain with efficient hardware-optimized counterparts.

Optimize Code/Data Loading

Improve processing speed by loading code/data in runtime from flash to RAM. For more information, see https://in.mathworks.com/matlabcentral/answers/673963-how-do-i-load-data-code-to-flash-and-run-from-ram-on-a-ti-c2000-device.

Inlined Parameter Behavior

Boost performance by changing Configuration Parameters > Code Generation > Optimization > Default parameter behavior to Inlined, optimizing default parameter behavior.

Fixed-Point Math Optimization

On devices without Floating Point Unit (FPU) support, avoid using floating-point operations and opt for fixed-point math to reduce computational overhead. You can use the IQMath blocks available in the C2000 library, which can be manually added during modeling.

CRL replacement happens when you select the correct datatype. Choosing datatypes for math and trigonometric operations imposes restrictions on using IQMath library functions.

Utilize CRL for Fixed-Point Models

For models using Fixed-Point math, the CRL replaces the operations with highly optimized TI IQ Math routines. Ensure no CRL misses due to rounding or saturation options. For more information, see

Leverage FastRTS Library

On devices with FPU support, use optimized floating-point math functions from the FastRTS library. For devices with FPU but no Trigonometric Math Unit (TMU), consider enabling FastRTS support.

Enable TMU with FPU

On devices supporting both TMU and FPU, select Enable TMU for more optimized floating-point math routines. This option offers even better performance compared to FastRTS and covers most of the routines found in FastRTS.
