`
`Accused Products
`Apple products incorporating Apple Ax processors (“Apple Ax System”) infringe at least Claim 1 of the ’804 Patent.
`
`U.S. Patent No. 6,317,804 (“’804 Patent”)
`
`Claim 1
`
`Claim 1
`1[pre]. A circuit arrangement for
`interfacing a plurality of functional
`blocks to one another in an integrated
`circuit device, the circuit arrangement
`comprising:
`
`Apple Ax System
`To the extent the preamble is limiting, the Apple Ax System comprises a circuit
`arrangement for interfacing a plurality of functional blocks to one another in an
`integrated circuit device.
`For example, the Apple Ax System comprises a circuit arrangement as described in the
`ARM AMBA (Advanced Microcontroller Bus Architecture) specification, Rev 2.0 and
`newer revisions.

`
`Claim 1
`1[a] a plurality of serial ports, each serial
`port associated with and coupled to a
`functional block via a point-to-point
`connection to permit external
`communication therewith, and each serial
`port including separate serial command,
`data and clock interconnects; and
`
`Apple Ax System
`The Apple Ax System comprises a plurality of serial ports, each serial port associated
`with and coupled to a functional block via a point-to-point connection to permit external
`communication therewith, and each serial port including separate serial command, data
`and clock interconnects.
`For example, the Apple Ax System comprises a plurality of serial ports associated with
`the ARM Advanced High-Performance Bus, each of which is coupled to the AHB
`master/slave, each of which including separate serial command interconnects (for
`example and not by way of limitation, HWRITE, HTRANS, HSIZE, HBURS,
`HPROT), data interconnects (for example and not by way of limitation, HWDATA,
`HRDATA), and clock interconnects (for example and not by way of limitation, HCLK,
`HLOCK).

`
`Claim 1
`1[b] an interface controller, coupled to
`each of the plurality of serial ports, the
`interface controller configured to
`selectively couple at least two of the
`plurality of serial ports to one another to
`define a logical communications channel
`between the functional blocks associated
`therewith.
`
`Apple Ax System
`The Apple Ax System comprises an interface controller, coupled to each of the plurality
`of serial ports, the interface controller configured to selectively couple at least two of
`the plurality of serial ports to one another to define a logical communications channel
`between the functional blocks associated therewith.
`For example, in the Apple Ax System the AMBA interface controller is coupled to each
`of the serial ports. The multiplexers of the interface controller are set up by the arbiter
`and decoder to couple a serial port of a selected master to a serial port of a selected
`slave to make a communications channel between the selected ports

`
`AMBA Specification, Rev. 2.0, May 13, 1999.
