A radio frequency (RF) transmitter is coupled to and controlled by a processor to transmit data. A physical layer circuit is coupled to the RF transmitter to encode and decode between a digital signal and a modulated analog signal. The physical layer circuit comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). The low rate channels generated by the low rate physical layer circuit (LRP) share a same frequency band as a corresponding high rate channel generated by the high rate physical layer circuit (HRP).

摘要:
A media access controller (MAC) generates a composite packet having an optimized format for carrying audio, video, and data traffic. A header portion of the composite packet is encoded separately from a data portion of the composite packet. A physical device interface (PHY) is coupled to the MAC. The PHY encodes and decodes between a digital signal and a modulated analog signal. The PHY comprises a high rate physical layer circuit (HRP) and a low rate physical layer circuit (LRP). A radio frequency (RF) transmitter is coupled to the PHY to transmit data.

摘要:
One of a linked list memories is selected as a defect marking memory and faults in rows of the defect marking memory are detected. Row addresses having at least one fault in defect address registers are stored. Faults in rows of other linked list memories are detected, where the other linked list memories are the linked list memories other than the defect marking memory and a marking code is stored for each row address of the other linked list memories in the defect marking memory, where a particular marking code indicates whether a particular row address has at least one fault. The defect address registers and the defect marking memory are searched when addresses of the linked list memories are linked and row addresses indicated as having at least one fault are skipped in the linking process.
