Check out H. Lam, C. Lee, and S.Y.W. Su, "A special function unit for database operations (SFU-DB): Design and performance evaluation," IEEE Trans. on Computers 40, 2 (March 1991) 263-275. The work was done at Univ. of Florida, Gainesville, under NSF support. The unit is designed around a distribution-sort algorithm, implemented using an "automatic retrieval memory". They claim that the unit can do db operations like relational join, elimination of duplicates, set union, set intersection, and set difference in linear time. (It's old work, of course, since the manuscript was submitted in Nov. 1988.) -- Mark Smotherman, CS Dept., Clemson University, Clemson, SC 29634-1906 mark@cs.clemson.edu or mark@hubcap.clemson.edu
