HYBRID PARALLEL/SERIAL BUS INTERFACE
First Claim
1. Apparatus for use in a wireless unit for controlling signal levels of wireless messages sent and received by the wireless unit, comprising:
- a transmitter (TX) gain control device (TX GCD) and receiver (RX) gain control device (RX GCD) for respectively controlling a gain of signals respectively sent by and received by said devices;
a GC controller for producing a data block having n data bits representing a gain value;
i lines each configured to transfer portions of the data block from the GC controller to a given one of the TX GCD and RX GCD, where 3≦
i<
n;
a data block converting device for converting the data block into i data block portions, each data block portion having a plurality m of control bits appended thereto, combinations of states of the m control bits collectively representing both a function and/or destination and the combination of states of the control bits;
each data block portion being applied to an associated one of said i lines;
the data block portions from said i lines being combined to reconstruct the original data block;
the data block being transferred to the given GCD based on a given combination of state of the control bits; and
the given GCD receiving the data block and adjusting a gain of the signal handled by the given GCD based on one or a plurality of methods using the gain value of the data block to thereby maintain the signal handled by the given GCD at a gain value determined by the GC controller.

Abstract
A hybrid serial/parallel bus interface has a data block demultiplexing device. The data block demultiplexing device has an input configured to receive a data block and demultiplexes the data block into a plurality of nibbles. For each nibble, a parallel to serial converter converts the nibble into serial data. A line transfers each nibble'"'"'s serial data. A serial to parallel converter converts each nibble'"'"'s serial data to recover that nibble. A data block reconstruction device combines the recovered nibbles into the data block. The data block is employed by a gain controller. Each nibble has at least two start bits whose states collectively represent both a function and/or destination.

12. A method for use by a wireless unit for controlling signal levels of wireless messages sent by a transmitter gain control device (TX GCD) and received by receiver gain control device (RX GCD) of the wireless unit, comprising:
-
producing a data block of n data bits, states of the n data bits collectively representing a gain value; converting the data block into i data block portions where 3≦
i<
n;providing each data block portion with a plurality of control bits; transferring each of the i data block portions and their associated control bits over an associated one of i lines; combining the data block portions transferred over said i lines to reconstruct the original data block; coupling the combined data block to one of said TX GCD and RX GCD based on the collective states of the control bits; and adjusting a gain of the signal handled by said one of said TX GCD and RX GCD according to one of a plurality of methods based on the gain value of the combined data block and the combination of states of the control bits. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
