TMS320F28377D: Using the TMS32F280049 TIDM-02000-Peak CAL code in TMS320F28377D CLA.

Dear TI Hello,

We are working on a converter static inverter and we want to use the CLA to reduce the CPU load.

Before starting the development we want to be sure about some hardware details.

Does CLA in the TMS320F280049 is the same as the TMS320F28377D?

We are starting the project and we want to use the TI code in TIDM-02000-Peak Current Controlled Mode PSFB DC-DC Power Converter already using the CLA, the question is it possible to use the same code in the TMS32028377D CLA?

Is there any hardware difference between the TMS320F280049 and TMS320F28377D CLAs?

Thank you in advance,

S.Tarik

    Hi Tarik,

    1. The CLA features vary slightly from device-to-device. For example, on the F2837xD, F2837xS, and F2807x, the CLA can support only one task at a given time and there is no nesting capability, which means the task is not interruptible. Hence, realistically, only one ISR can be offloaded to the CLA. On the F28004x, the CLA supports a background task from which a regular CLA task can nest. This configuration enables offloading two ISR functions to the CLA.

    2. You can use the same code in the TMS32028377D CLA since we only use one task in cla.

    Regards,
