Abstract: Integrated circuits and integrated circuit dies include TSVs laid out in symmetrical patterns. Because of the symmetrical arrangement of the TSVs and associated routing patterns, an integrated circuit is able to support operation of multiple similar dies that are placed in different positions in the integrated circuit. This in turn simplifies the design and production of the multiple similar dies, thus reducing development and manufacturing costs for the corresponding integrated circuits.

Abstract: There is provided a semiconductor device for multiplexing across a plurality of shared Input/Output (I/O) pins. The semiconductor device comprises a first core for operation of a first function, a second core for operation of a second function, a multiplexer and an additional hardware module. The multiplexer is arranged to set the I/O pins to the first function or to the second function at power up. The hardware module comprises an arbiter arranged to receive requests from the cores for use of the I/O pins and to grant use of the I/O pins to a selected core as required. Thus, the hardware module can switch functions dynamically and dual mode multiplexing is enabled.

Abstract: An LED array arrangement that reduces the number of control inputs needed to operate it is described. The reduction in the number of control pins is achieved through the use of logical ‘AND’ decoding and multiplexing of the control input signals.
