Bug fix:
The SOPC Builder top-level system module included an extra, unnecessary output
port for systems with very small address spaces.
Initial release of the Nios II/s core.
Added user-configurable options affecting multiply and shift operations. Now
designers can choose one of three options:
(1) Use embedded multiplier resources available in the target device family
(previously available).
(2) Use logic elements to implement multiply and shift hardware (new option).
(3) Omit multiply hardware. Shift operations take one cycle per bit shifted;
multiply operations are emulated in software (new option).
Added user-configurable option to include divide hardware in the ALU. Previously
this option was available for only the Nios II/f core.
Added cpuid control register.
