ISA

The nu+ instructions have a fixed length of 32 bits, divided into eight formats:

• The R type includes the logical and arithmetic operations and memory operations.

• The I type includes the logical and arithmetic operations between a register operand and an immediate operand.

• The MOVEI type includes the load operations of an immediate operand in a register.

• The C type used for control operations and for synchronization instructions.

• The JR type includes jump instructions.

• The J type includes jump instructions with the relative addressing mode.

• The M type includes the instructions used to access memory.

• The M-poly type is used for memory instructions which uses a polyhedral access pattern.
