In addition to the well understood features of the VLIW style of architecture, the space of processors that we are interested in exploring is characterized by the HPL-PD architecture family which includes features such as predication, control and data speculation, rotating registers, and explicit source and destination specifiers for load and store operations at various levels of the memory hierarchy. It also supports multiple vision algorithms in the same hardware platform while supporting runtime reconfigurability, architectural flexibility, and extensibility. • All functional units share the use of a common large register file.
