Abstract
Aspects for collision recovery interface support in a home phoneline networking alliance (HPNA) control chip are described. The aspects include providing transmit data path logic to receive and transmit data packets within the HPNA control chip. The transmit data path logic is consolidated to include a transmit state machine that handles interfacing the transmit data path logic to at least two separate collision recovery logic means of the HPNA control chip through a minimal number of generic interface signals.
Claims18
A method for collision recovery interface support in a home phoneline networking alliance (HPNA) control chip, the method comprising the steps:
- (a) providing transmit data path logic to receive and transmit data packets within the HPNA control chip;
- and
- (b) consolidating the transmit data path logic to include a transmit state machine that handles interfacing the transmit data path logic to at least two separate collision recovery logic means of the HPNA control chip through a minimal number of generic interface signals.
A system for collision recovery interface support in a home phoneline networking alliance (HPNA) control chip, the system comprising:
- at least two collision recovery means for providing collision recovery in the HPNA control chip according to at least two data rate standards;
- and
- a transmit data path logic means including a transmit state machine that interfaces with the at least two collision recovery means through a minimal number of generic interface signals.
A home phone networking alliance (HPNA) network control chip capable of collision recovery interface support, the chip comprising:
- a media independent interface (MII);
- a physical layer (PHY);
- and
- a media access control (MAC) coupled between the MII and the PHY, the MAC further comprising at least two collision recovery means for providing collision recovery according to at least two data rate standards, and a transmit data path logic means including a transmit state machine that interfaces with the at least two collision recovery means through a minimal number of generic interface signals.
