IC FOR HANDHELD COMPUTING UNIT OF A COMPUTING DEVICE
First Claim
1. An integrated circuit (IC) comprises:
- a processing module;
on-chip memory;
one or more block input/output (I/O) interfaces for coupling to one or more off-chip block I/O devices;
one or more character I/O interfaces for coupling to one or more off-chip character I/O devices when active;
a main memory interface for coupling to off-chip main memory;
a baseband processing module coupled to convert outbound data into an outbound symbol stream and to convert an inbound symbol stream into inbound data;
a radio frequency (RF) section coupled to convert the outbound symbol stream into an outbound RF signal and to convert an inbound RF signal into the inbound symbol stream;
a processing module interface for coupling the processing module to an off-chip connection structure, wherein, when a handheld computing unit that includes the IC is docked to an extended computing unit, the off-chip connection structure couples the handheld computing unit to the extended computing unit such that the IC is in a docked mode; and
an IC bus structure coupled to the processing module, the on-chip memory, the one or more block I/O interfaces, the one or more character I/O interfaces, the main memory interface, and the baseband processing module, wherein, when the IC is in a remote mode, the one or more character I/O interfaces are active and the processing module interface is inactive and wherein, when the IC is in the docked mode, at least one of the one or more character I/O interfaces is inactive and the processing module interface is active.

Abstract
An IC includes a processing module, on-chip memory, one or more block input/output (I/O) interfaces for coupling to one or more off-chip block I/O devices, one or more character I/O interfaces for coupling to one or more off-chip character I/O devices when active, a main memory interface for coupling to off-chip main memory, a baseband processing module, an RF section, a processing module interface, and an IC bus structure. The processing module interface couples the processing module to an off-chip connection structure, wherein, when a handheld computing unit that includes the IC is docked to an extended computing unit, the off-chip connection structure couples the handheld computing unit to the extended computing unit such that the IC is in a docked mode.
