Fig. 5.

Multiple rounds of SIMD computation. (A) Three rounds of Rule 110 computation were performed on an input mix with 5 distinct initial values (columns). Lower panels show the distribution of output values for initial values 0001 and 1101. Registers reacted with instruction strands at 25 ℃. The reaction time for every instruction was 2 min except for Instruction 2, which was 10 min. (B) The mix of inputs that underwent selective erasure from Fig. 4B went through another round of binary counting computation. Registers reacted with Instruction 1 strands at 40 ℃, and all other instruction strands at 25 ℃. For (A) and (B), the registers were composed of chemically synthesized DNA.
