Abstract
A signal processor comprises a plurality of processing circuits for carrying out various kinds of processing which differ from one another; a memory circuit provided commonly for respective processing circuits, and a control circuit for carrying out access control between the respective processing circuits and the memory circuit, characterized in that the control circuit carries out address control in different units in accordance with the respective processing circuits.
Claims15
A signal processor comprising:
- a plurality of processing means for carrying out various kinds of processing which differ from one another;
- memory means provided in common for said plurality of processing means;
- and
- control means for carrying out access control between respective processing means and memory means,
- wherein said control means carries out address control in different units in accordance with respective processing means.
A signal processor comprising:
- a plurality of processing means for carrying out various kinds of processing which differ from one another;
- memory means provided in common for said plurality of processing means;
- and
- control means for carrying out access control between respective processing means and memory means,
- wherein said control means executes time sharing processing by preferentially carrying out access of data with high processing priority.
A signal processor comprising:
- a plurality of processing means for carrying out various kinds of processing which differ from one another;
- memory means provided in common for said plurality of processing means;
- means for setting parameters respectively conforming to a plurality of kinds of data to be processed;
- and
- control means for carrying out access control between respective processing means and memory means,
- wherein said control means makes said address control different according to the parameters conforming to said data.
A signal processor comprising:
- a plurality of processing means for carrying out various kinds of processing which differ from one another;
- memory means provided in common for said plurality of processing means;
- mode designation means for designating an operation mode;
- and
- control means for carrying out access control between respective processing means and memory means according to the operation mode designated by said mode designation mode,
- wherein said control means makes the priority of said address control different according to the operation mode conforming to said data.
A signal processor comprising:
- a plurality of processing means for carrying out various kinds of processing which differ from one another;
- and
- memory means provided in common for said plurality of processing means and having an input/output part capable of transferring data in a specified unit at a high speed,
- wherein the specified unit of data which can be transferred at a high speed in said input/output part is made correspond to a unit of data in said respective means
