Abstract:
A data processing system comprising:a processing unit for executing instructions; anda memory for storing a set of routines for handling exceptions, for storing an exception table, and for storing a jump table;the exception table being organized into segments, each of the segments for storing a plurality of instructions for handling a particular exception, the segments each having a segment starting address, the jump table having a plurality of entries, each of the plurality of entries having an entry address, and each of the plurality of entries for containing a branch instruction for branching to one of the set of routines; anda control logic unit, coupled to the memory, for mapping the memory as the exception table in response to a control bit being in a first logic state, the control logic unit for mapping the memory as the jump table in response to the control bit being in a second logic state.
