TMS320F28375S: Memory mapping access in RAM

Part Number: TMS320F28375S

                      Size               Start Address               End Address

Hi,

From TMS320F28375S Data Sheet following memory mapping is observed.

GS11RAM     4Kx16            0x00017000               0x00017FFF

GS12RAM     4Kx16            0x00018000               0x00018FFF

GS13RAM     4Kx16            0x00019000               0x00019FFF

GS14RAM     4Kx16            0x0001A000               0x0001AFFF

GS15RAM     4Kx16            0x0001B000               0x0001BFFF

Please let me know if we can merge half of the GS13RAM with RAMLS3D01GS013 (program memory) and other half with GS13_14_15RAM ( data memory)

                                            Start Address         End Address        Length

RAMLS3D01GS013           0x00009800           0x00019D97       0x00010597

GS13_14_15RAM              0x00019D97         0x0001BFF7       0x00002260          

Thanks,

S. Vennela

    There shouldn't be any issue, you can merge the GSx and LSx RAMs. It's best to use contiguous memories for storing items like functions or arrays, just as a recommendation.
