Abstract: A system and method for efficiently performing a data transfer operation in an electronic system preferably includes a processor that may initially create a DMA structure in a block transfer memory device. The DMA structure may preferably include one or more command structures for performing DMA data transfer operations. The processor may subsequently program local control registers of a DMA engine with selected DMA transfer information in response to a DMA data transfer requirement. The processor may then instruct the DMA engine to perform the required DMA data transfer operation. Next, the DMA engine may responsively copy one or more of the command structures from the block transfer memory device into local command registers that are coupled to the DMA engine. The DMA engine may then reference the foregoing control registers and command registers to thereby efficiently perform one or more DMA data transfer operations.

Abstract: A voice scratchpad implemented in a wireless telephone allows the user to record important information gathered during a phone conversation. The wireless telephone includes signal processing means and memory means for recording at least one message or memo which is spoken over the telephone. The telephone also includes controls for initiating the recording of such a memo and for retrieving and replaying the memo. Indexing may be included which allows the system to record and replay a plurality of memos. The user of the phone can thus record important information in a memo on the voice scratchpad without the need for paper or the concentration and effort required for writing.
