Towards the code size problem of Transfer Triggered Architecture(TTA)

an efficient technique for code compression is presented.The template scheme is improved to efficiently eliminate the redundant empty transfer slots and invalid immediate encodings.Then

based on the spatial locality of data transports

a vertical dictionary-based program compression method is presented to further reduce the compression ratio.A one-cycle decompression engine is described for real-time decoupling decompression with little hardware cost.The experiment shows that this technique achieves the compression ratio of nearly 37.2%.The total area of the processor core and the local instruction memory could be reduced by about 29% and power consumption by nearly 23% respectively

with the extra execution overhead of nearly 4%.
