The architecture of a specific chip for RNA secondary structure prediction

The architecture of a BioAccel (internal code) chip for RNA secondary structure prediction is described in the letter. The system is based on a BioBus (internal code), whose distinguishing features are: Two separated control and data channels, and a slave-associated arbitration scheme. Two reference systems based on the AMBA AHB bus and Coreconnect bus are introduced to evaluate the performance of the system. The simulation results are attractive.The average communication bandwidth of the chip is increased at severalfold, and the read and write latencies are reduced about 40 percent.
