Abstract
A system includes a direct memory access controller and a memory coupled to the direct memory access controller. The memory stores a linked list of records. Each record contains a first field determining the number of fields of a next record. For example, each record can be representative of parameters of execution of a data transfer by the direct memory access controller.
Claims20
A system comprising:
- a direct memory access controller;
- and
- a memory coupled to the direct memory access controller, the memory storing a linked list of records, each record containing a first field indicating the number of fields of a next record, wherein each field of a record is representative of a content to be programmed in a register of a register bank.
A system comprising:
- a central processing unit;
- a direct memory access controller coupled to the central processing unit via a bus;
- a plurality of registers associated with the direct memory access controller;
- and
- a memory coupled to the direct memory access controller, the memory storing a linked list of records, each record containing a first field determining the number of fields of a next record, wherein each record is representative of parameters of execution of a data transfer by the direct memory access controller.
