US Patent:
20110185208, Jul 28, 2011
Filed:
Sep 30, 2010
Appl. No.:
12/895702
Inventors:
Derek Iwamoto - Sunnyvale CA, US
Steven J. Sfarzo - Los Gatos CA, US
Ryan Schmidt - San Jose CA, US
Derrick Carty - Los Altos CA, US
Keith Cox - Sunnyvale CA, US
Assignee:
APPLE INC. - Cupertino CA
International Classification:
G06F 1/32
US Classification:
713323
Abstract:
A data processing system that uses memory power reduction in a sleep state. The system can include a volatile memory and at least one data input peripheral and a logic circuit that is configured to manage power consumption of the data processing system for a sleep of the system. The logic circuit can be coupled to the volatile memory and can be configured to turn off power to the volatile memory in response to an event, occurring during the sleep state, but to otherwise remain in the sleep state. The sleep state can be an ACPI complaint S3 sleep state in which the volatile memory, such as DRAM, is powered off after a period of user inactivity during the S3 sleep state.

Aggregating Multiple Data Streams On A Communication Link

View page
US Patent:
20220353736, Nov 3, 2022
Filed:
Jul 19, 2021
Appl. No.:
17/379088
Inventors:
- Cupertino CA, US
Venkatesh Rajendran - San Jose CA, US
Derek Fujio Iwamoto - Sunnyvale CA, US
International Classification:
H04W 28/06
H04W 76/10
H04W 4/18
H04W 56/00
Abstract:
A host device establishes a wireless communication link with a client device, and implements a wired communication standard on the link to transfer a first data stream. To increase data throughput while complying with the standard, the host device replaces synchronizing information in a packet to be sent during a first synchronizing frame with configuration information indicating that packet exchange data of a second data stream is to be sent or received during a second synchronizing frame. The host device sends or receives the packet exchange data of the second data stream to or from the client device during the second synchronizing frame via the wireless communication link. The host device may send or receive the packet exchange data of the second data stream during delays or idle periods between sending and/or receiving packets of the first data stream via the wireless communication link according to the wired communication standard.

Interface Emulator Using Fifos

View page
US Patent:
20170277648, Sep 28, 2017
Filed:
Jun 13, 2017
Appl. No.:
15/621265
Inventors:
- Cupertino CA, US
Josh P. de Cesare - Campbell CA, US
Brijesh Tripathi - Los Altos CA, US
Derek Iwamoto - San Francisco CA, US
Shane J. Keil - San Jose CA, US
International Classification:
G06F 13/42
G06F 13/10
G06F 13/40
G06F 13/38
Abstract:
An interface emulator for an IC is disclosed. An interface emulator includes a first first-in, first-out memory (FIFO) and a second FIFO. The first FIFO is coupled to receive data from an access port and a second FIFO coupled to receive data from at least one functional unit in the IC. The access port may be coupled to a device that is external to the IC. The external device may write information into the first FIFO, and this information may subsequently be read by a functional unit in the IC. Similarly, the functional unit may write information into the second FIFO, with the external device subsequently reading the information. Information may be written into the FIFOs in accordance with a predefined protocol. Thus, a particular type of interface may be emulated even though the physical connection and supporting circuitry for that interface is not otherwise implemented in the IC.
