A data processor 2 has privilege levels associated with it including a user level and a privileged level. The processor 2 also has multiple stack memories which can be used including one or more process stacks, a main stack and a deep stack. The stack memory to be used is de-coupled from the privilege level. An activation level state variable tracking the number of pending exceptions is held by the processor and used to modify which stack memory stores pending state values when an exception occurs. If the system is at a base level of activation, corresponding to currently no pending exceptions, then when an exception occurs the current state data is saved on the process stack with the main stack being available for the exception handling code. Particular exceptions can be flagged as requiring use of a deep stack rather than either the process stack or the main stack. If the system is not at the base level of activation, then the main stack is used to save state variables when an exception occurs rather than the process stack.

The present invention is directed to a method and system for minimizing memory access latency during realtime processing. The method includes a mechanism for marking information that will be accessed during realtime processing. The marked information may include code, data, heaps, stacks, as well as other information. The method includes support for locking down all of the marked information so that it is present in a computing machine's physical memory so that no page faults will be incurred during realtime processing. The method additionally enables realtime processing code to allocate and free memory in a non-blocking manner. It does so by enabling the creation of heaps for use during realtime processing, wherein each heap supports allocating and freeing memory in a non-blocking fashion. Each heap tracks freed memory blocks using individual non-blocking tracking lists for each memory block size supported by that heap. If a memory allocation request to a heap can be satisfied by using a memory block available on one of the lists of freed memory blocks, the method includes allocating the available memory block by popping the memory block from the tracking list. If no freed memory blocks of the desired size are available, then the method includes traversing a separate set of source memory blocks for that heap, and making the allocation in a non-blocking fashion from one of those blocks.

A technique for performing buffer management on a network device without using static random access memory (SRAM). In one embodiment, a software-based buffer management scheme is used to allocate metadata buffers and packet buffers in one or more dynamic random access memory (DRAM) stores. As metadata buffers are allocated, pointers to those buffers are entered into a scratch ring. The metadata buffers are assigned for corresponding packet-processing operations.

In one embodiment, the technique is facilitated by an application program interface (API) that contains buffer management functions that are callable by packet-processing code, wherein the are names and parameters of the API functions are identical to similar functions used for conventional buffer management operations employing SRAM.
