Abstract
A method for swapping code in a digital signal processor includes determining whether the code is present in an external memory that is external to the digital signal processor or whether the code is present in an internal memory that is internal to the digital signal processor and copying the code from the external memory to a swap area section of an internal memory when it is determined that the code is present in the external memory.
Claims44
A method for swapping code in a digital signal processor, comprising:
- determining whether the code is present in an external memory that is external to the digital signal processor or whether the code is present in an internal memory that is internal to the digital signal processor;
- and
- copying the code from the external memory to a swap area section of the internal memory when it is determined that the code is present in the external memory.
A system for swapping code in a digital signal processor, comprising an external memory that is external to the digital signal processor and an internal memory that is internal to the digital signal processor, the internal memory comprising a low latency code section for storing low latency code and a swap area section for storing code that has been copied from the external memory.
A computer system comprising:
- a processor;
- and
- a program storage device readable by the computer system, embodying a program of instructions executable by the processor to perform steps for swapping code in a digital signal processor, the steps comprising:
- determining whether the code is present in an external memory that is external to the digital signal processor or whether the code is present in an internal memory that is internal to the digital signal processor;
- and
- copying the code from the external memory to a swap area section of the internal memory when it is determined that the code is present in the external memory.
