“…(11) and (12) is that the partial products are accumulated column-wise in (12) rather than the row-wise accumulation in (11). As a result, x i need only be loaded once during the complete processing and then all entries in all blocks at the same column can be fed into the filter continuously.…”

“…Since the FIR filtering and the accumulation can fully utilize the computation power of the ring processor they are the only operations to be mapped to the ring processor. The resulting program is a simple variation of one for FIR filtering that can be found in [11]. Here, we focus our discussion on the microcontroller design, especially the two most important functions of the microcontroller.…”

“…The design of a ring-structured processor [11] attempts to find a balance in the signal processing arena between full-custom IC implementations and the use of generalpurpose signal processors. Unlike the general-purpose processor, the ring processor does not try to accommodate "all signal processing applications," but rather, realizes certain types of algorithms.…”

We present the fixed-point analysis and VLSI realization of a maximum-power blind beamforming algorithm. This algorithm consists of the computation of a correlation matrix and its dominant eigenvector, and we propose that the latter be accomplished by the power method. After analyzing the numerical stability of the power method, we derive a division-free form of the algorithm. Based on a block-Toeplitz assumption, we design an FIR filter based system to realize both the correlation computation and the power method. Our ring processor, which is optimized to implement digital filters, is used as the core of the architecture. A special technique for dynamically switching filter inputs is shown to double the system throughput. VLSI design is discussed in detail and chip fabrication results are presented.
