Short Desc. : Pro Series® Family
Overview :
Pro Series® cores offer unprecedented value by enabling SoC designers to write their own instruction set extensions and create highly differentiated, highly competitive products. Using standard tools and software, designers can implement instruction extensions to significantly increase performance, reduce power consumption, implement critical operations and more.
Features : - As many instructions as an expert designer needs can be added
- The encoding of the user-interpretable bits in a CorExtend™ instruction is completely up to the user
- The CorExtend block is tightly coupled to the integer execution unit
- The CorExtend block receives the full instruction word and up to two operands from the register file
- Each instruction extension may return one result to the register file
- Local state values can be stored in the CorExtend block
- Pipeline dependencies are always checked for both operand and destination registers
- Only fixed integer instructions are allowed
- Instructions may be single- or multi-cycle
- The CorExtend block is largely independent of the Pro core integer pipeline
- The CorExtend block can stall the integer pipeline if desired
- Software can check if the CorExtend feature is implemented through the configuration register
