I keep thinking of a dram with a row of MAC units and registers along the row outputs. A vector is then an entire dram row. Access takes longer then the math, so slower/smaller multi-cycle circuits could be used. This would probably require OS level allocation of vectors in dram, and management of the accumulator vector (it really should be a row, but we need a huge register to avoid extra reads and writes. The dram will also need some kind of command interface.
