Claims1
A microprocessor based system comprising:
- a microprocessor;
- and
- a memory comprising instructions, which, when executed by the microprocessor, cause the microprocessor to store packet data in a physical address space of the memory;
- to generate a logical index of the physical address space, the logical index has a logical address space twice the size of the physical memory address space, the logical index to logically map the physical memory addresses, such that each physical memory address maps to two logical addresses;
- and to generate an access pointer to provide bi-directional logical access to the logical address space.
