AbstractThis paper describes some issues of parallel list processing under data flow control. Also a new type of list‐processing oriented data flow machine is presented which achieves pipelined processing among activated functions. Performance evaluation through software simulation gave the following conclusions.(1) This machine can utilize a high degree of parallelism even for simple programs due to the partial function‐body execution and lenient cons effects.(2) Parallel processing overhead does not affect the processing time.(3) Memory contention is reduced by dividing the structure memory into many banks and by uniformly distributing cons operations in each b
