Abstract
A method for managing a discontinuous call stack is disclosed to more efficiently use the memory of devices without a memory management unit. The method comprising: storing a stack location indicator indicating a top of said discontinuous call stack in a data store; using said stack location indicator to identify a current memory block of said discontinuous call stack from said plurality of memory blocks, said current memory block storing said top of said discontinuous call stack and a previous location indicator indicating a location of a previous memory block of said discontinuous call stack; determining an amount of memory available in said current memory block; determining an amount of memory required for a stack frame; determining an amount of memory required for an interrupt allowance; allocating said stack frame and said interrupt allowance at least one memory block from said plurality of memory blocks in response to said determinations; storing said stack frame in said allocated memory block; and updating said stack location indicator in said data store.
