Since the relationship is much stronger at the bit level than at the work level and most relations can be described as shift-and-operate computations, these kinds of relations can be formulated as recursive equations, from which the systolic array can be built without deriving the dependence graph of the bit-level computation. Some design examples for bit-recursive systolic array presented: multiplier, inner product and convolution correlation.<<ETX>>","PeriodicalId":339807,"journal":{"name":"[1988] Proceedings.

Conditions are established with respect to the dependency of the testing process on the signal flow. Each set of testability conditions establishes the controllability and observability of a test vector. These conditions are proved to be applicable under different processing models related to the three inputs of each cell in the array. Complexity issues, such as number of test vectors and time units, are discussed.<<ETX>>","PeriodicalId":339807,"journal":{"name":"[1988] Proceedings.

Both 1-D and 2-D MLD processors with large constraint length (>8) have been derived. Radix-4p processing elements and delay commutating switching processors for MLD have been concatenated to construct a pipeline MLD processor. The pipeline length can be adapted to meet the time/area constraints for various applications. A 2-D MLD array processor is also presented. Processing data are modulized, data transmission are embedded into processing elements, and a fixed-size 2-D MLD array is derived to meet high-data-throughput requirements.<<ETX>>","PeriodicalId":339807,"journal":{"name":"[1988] Proceedings.

The architecture relies heavily on a triangular systolic structure as a means of solving recursive least-squares problems based on the QRD algorithm due to J.G. McWhirter (1983). A manifold of triangular systolic arrays, which in the limit takes the form of a cosmic cube, is used. With the proper time skew format for the data flow, it is shown that the cosmic cube beamformer can concurrently and simultaneously process the data from the rows and columns of array antennas with a speed comparable to the 1-D case. Data memory requirements are modest. It is felt that the beamformer has promise for real-time beamforming with planar array antennas.<<ETX>>","PeriodicalId":339807,"journal":{"name":"[1988] Proceedings.

An easy realization of this array on a VLSI circuit is thus possible, and the structure of an elementary processor cell is given. The sorting algorithm is well suited to solve problems of data transfer in locally connected parallel processors with distributed energy.<<ETX>>","PeriodicalId":339807,"journal":{"name":"[1988] Proceedings.
