Hi,

It would run in Flash.

hi Himsnshu,

thank you for your reply. Code execution speed for both RAM and Flash is same or not in TMS320F28069.

Hi Manoj,

Code execution will be faster for RAM compared to FLASH.

Hi Himanshu,

what ever the section i.e., RAM or Flash,But CPU will fetch, decode, execute and store(pipelining) . How we can differentiate code will execute faster in RAM when compared with Flash.

Manoj,

Flash memory is slower than RAM. Flash takes more cycles to provide the data that CPU asks for. As you might have seen in the datasheet (Table 5-17. Minimum Required Flash/OTP Wait States at Different Frequencies), user application should configure some wait-states for Flash to return the valid data/code that CPU requests for. However, a prefetch mechanism called flash pipeline can be enabled to improve fetch performance for linear code execution. See section 1.2.3.2 Flash Pipeline Mode in TRM at http://www.ti.com/lit/ug/spruh18g/spruh18g.pdf for more details.

Thanks and regards,
