Abstract
The data processor for processing operation data stored in a memory connected to an external bus in the order of operations includes: an interface section for holding a parameter required for transfer of the operation data; an operation section receiving the operation data from the interface section for performing predetermined processing; and an operation memory for storing the operation data transferred. The interface section sequentially transfers the operation data from the memory connected to the external bus to the operation memory using the parameter, and sequentially transfers the operation data from the operation memory to the operation section.
Claims11
A data processor for processing operation data stored in a memory connected to an external bus in the order of operations, comprising:
- an operation memory for storing the operation data transferred;
- an interface section for holding addresses of the operation data required for transfer of the operation data;
- and
- an operation section receiving the operation data from the interface section for processing a command included in the operation data,
- wherein the interface section sequentially transfers the operation data from the memory connected to the external bus to the operation memory using the address, and sequentially transfers the operation data from the operation memory to the operation section, and
- wherein the interface section transfers transfer information for transfer of operation data to be next processed to the operation memory, together with the current operation data, and when reading the transfer information from the operation memory, the interface section transfers the operation data to be next to processed corresponding the transfer information from the memory connected to the external bus to the operation memory.
A data transfer method for transferring operation data stored in a memory connected to an external bus in the order of operations, comprising the steps of:
- storing addresses of the operation data required for transfer of the operation data;
- and
- transferring the operation data sequentially from the memory connected to the external bus to an operation memory using the addresses, and transferring the operation data sequentially from the operation memory to an operation section in which processing of a command included in the operation data is performed, wherein the step of transferring the operation data comprises the steps of:
- transferring transfer information for transfer of operation data to be next processed to the operation memory together with the current operation data;
- and
- when reading the transfer information from the operation memory, transferring the operation data to be next processed corresponding to the transfer information from the memory connected to the external bus to the operation memory.
