In a display device using a delta arrangement, in a case where a circuit of a large number of elements such as a static memory is arranged every pixel, a wire becomes complicated to cause wiring delay. A shape of a pixel electrode is formed polygonally to arrange in a case where the number of elements such as a static memory is large or in a case where an area of an element required to be included in a pixel is large in a delta arrangement. The shape of the pixel electrode is arranged in a polygon so that a wire along a pixel shape can be used. Even in a case of a pixel with a large number of elements, parasitic resistance of a wire and parasitic capacitance of a wire can be reduced so that wiring delay can be solved.

A deep-pipeline system substantially reduces the overhead of setup delays and pipeline delays by dynamically controlling access of a plurality of configuration register sets by both a host central processing unit (CPU) and the stages of the pipelines. A master configuration register set is loaded with configuration parameters by the host CPU in response to an index count provided by a setup-index counter. A plurality of other counters are employed to track timing events in the system. In one embodiment, a run-index counter provides a run-index count to the first stage of the pipeline that is propagated along the stages, enabling configuration register sets to transfer configuration parameters to the stages of the pipeline when required to enable processing of a task. In an alternative embodiment, a plurality of D flip-flops sequentially propagates a state for successive registers, so that the setup-index counter is not required.

During the transmission of data packets received on a wired connection via a first interface (e.g. IEEE 1394 interface) via a second interface designed for the wireless transmission of data, e.g. HIPERLAN / 2 interface, the problem exists that between receiving the data and transmitting the data via the second interface a relatively large delay time can arise which must be bridged by means of a suitably dimensioned buffer memory. The invention provides means that enable the maximum delay time to be further reduced. For this purpose, according to the invention, the necessary processing of the received IEEE 1394 bus packets is already performed section by section immediately after a received data packet has arrived. After the complete number of bus packets falling within a transmission frame has been received, there is therefore no longer any lengthy processing time required and the probability of missing the time slots reserved in the next transmission frame is significantly reduced. The buffer memory for bridging the delay time period can therefore be correspondingly smaller.
