Part Number: TMS320F28379D

Tool/software: Code Composer Studio

hello

I would like to know if cache memory is enabled in F28379D controller. how it is used between CPU1 and its CLA.

1. Does CLA use Cache memory ?

2. is cache memory partitioned between CPU1 and its CLA when executing ?

thanks,

Nagesh

    Nagesh,

    There is no cache memory. CLA have access to LSx RAM which is shared with CPU as well. User can configure to make LSxRAM accessible from CLA only.

    Hi Vivek, 

    Thank you for your response.

    I want to make my understanding more clearer

    I came across section 13.1 Introduction to Flash and OTP Memory :

    " how to improve flash performance by enabling the flash prefetch/cache mode ".

    this cache mode is used only when data is fetch from FLASH .

    also CLA cannot use cache and will be used only to communicate to CPU1 using the message RAM. also i would like to know that CLA cannot access FLASH.

    thanks
