1. A method for a memory address alignment comprising:

configuring one or more structure(s) of naturally aligned plurality of buffers;

providing a return address pointer in a buffer of one of the one or more structure(s) of naturally aligned plurality of buffers;

determining a configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers;

calculating a remainder as the pointer of the return address modulo the parameter specifying a buffer size;

subtracting the calculated remainder from the return address pointer to yield a naturally aligned base address; and

providing a stacked address pointer determined in accordance with the applied modulo arithmetic.

2. The method as claimed in claim 1 , wherein the configuring one or more structure(s) of naturally aligned plurality of buffers comprises:

initializing for each of the one or more structure(s) of naturally aligned plurality of buffers one or more configuration register(s), wherein one of the one or more configuration registers specifies a size of a buffer; and

configuring one or more structure(s) of naturally aligned plurality of buffers in accordance with the specified size.

3. The method as claimed in claim 2 , wherein the initializing further comprises:

initializing an additional one of the one or more configuration registers specifying a buffer offset; and

the configuring comprises configuring one or more structure(s) of naturally aligned plurality of buffers in accordance with the specified size and the specified buffer offset.

4. The method as claimed in claim 1 , wherein the determining a configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers comprises:

determining a configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers in accordance with the provided return address pointer.

5. The method as claimed in claim 1 , wherein the determining a configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers comprises:

determining a configuration of the one of the one or more naturally aligned buffer structure by providing an identifier of the one of the one or more structure(s) of naturally aligned plurality of buffers.

6. The method as claimed in claim wherein the providing a stacked address pointer determined in accordance with the applied modulo arithmetic comprises:

providing a return address pointer to a naturally aligned base address when no buffer offset is specified in the determined configuration.

7. The method as claimed in claim 1 , wherein the providing a stacked address pointer determined in accordance with the applied modulo arithmetic comprises:

providing a sum of a naturally aligned base address and a buffer offset specified in the determined configuration.

8. An apparatus for memory address alignment, comprising:

one or more structure(s) of naturally aligned plurality of buffers;

a returning entity configured to provide a return address pointer in a buffer of the one or more structure(s) of naturally aligned plurality of buffers; and

a hardware or software entity configured to:

determine a configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers;

calculate a reminder of the pointer of the return address modulo the parameter specifying a buffer size;

to subtract the calculated modulo from the return address pointer to yield a naturally aligned base address; and

provide a stacked address pointer determined in accordance with the applied modulo arithmetic.

9. The apparatus as claimed in claim 8 , wherein each of the one or more structure(s) of naturally aligned plurality of buffers comprises:

a plurality of buffers having a specified size.

10. The apparatus as claimed in claim 9 , wherein the specified size is different for each buffer in the plurality of buffers.

11. The apparatus as claimed in claim 8 , wherein each buffer in at least one of the plurality of buffers comprises a specified buffer offset.

12. The apparatus as claimed in claim 8 , wherein the hardware or software entity determines the configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers in accordance with the provided return address pointer.

13. The apparatus as claimed in claim 8 , wherein the hardware or software entity determines the configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers by being configured to:

receive from the returning entity an identifier of the one of the one or more structure(s) of naturally aligned plurality of buffers; and

to determine the configuration of the one of the one or more structure(s) of naturally aligned plurality of buffers in accordance with the received identifier.

14. The apparatus as claimed in claim 8 , wherein the hardware or software entity provides the stacked address pointer determined in accordance with the applied modulo arithmetic by being configured to:

provide a return address pointer to the naturally aligned base address when no buffer offset is specified in the determined configuration.
