Self-configuration of a large area integrated multiprocessor system for video applications

An architecture of a multiprocessor coding system suitable for large area integration has been developed. Application field is video coding according to the international standards I S 0 or similar methods. It is based on processor nodes, which consist of a 1.9 GOPS video signal processor AxPe, 4 MBit of embedded DRAM, and digital video interfaces for data input and output as well as for inter-processor communication. Four of these processor nodes can be fabricated with a single mask set on a 0.25pm CMOS circuit of 2x2 cm2, which is called AxPe subsystem. By overlapping manufacturing and cutting out of 2x2 of AxPe subsystems aferwards, a large area integrated circuit (LAIC) with 16 processor nodes can be realized. The upper metal layers of each AxPe subsystem contains connection structures at the chip boundaries for this purpose. Redundancy techniques ensure the functionality of the LAIC even in the case of defect processor nodes.

A novel laser-switch has been developed, designed and manufactured in a standard 6 level metal CMOS process. The redimensioned laser-switches combine a laser link and via (fuse) corresponding to minimum design rules in a single device. Due to vertical arrangement of the linking and the cutting structure (via), an area reduction of more than 30% is achieved, compared to laser arrays utilizing traditional laser structures. Simultaneous connecting and disconnecting reduces the processing time by SO%, since an additional process step is omitted. The resistance of the formed link structures is very low (R/2r12mrd,on=0.065 R rRl~xlomrdtun =0.118 a). Optimal values have been found for laser parameters to process the cutting structure with 100% yield. A first estimation of life-time results in to 1=22 a. Arrangements of laser-switches for bus configuration and repair, and for overwriting static configuration signals are proposed,
