-+;;     Load data from the memory and produce the loaded data. The result is
-+;;     ready at MM.
-+;;   LMW(N, M)
-+;;     There are N micro-operations within an instruction that loads multiple
-+;;     words. The result produced by the M-th micro-operation is sent to
-+;;     consumers. The result is ready at MM.
-+;;   MUL, MAC
-+;;     Compute data in the multiply-adder and produce the data. The result

-+;;     Require operands at EX.
-+;;   ALU_SHIFT_Rb
-+;;     An ALU-SHIFT instruction consists of a shift micro-operation followed
-+;;     by an arithmetic micro-operation. The operand Rb is used by the first
-+;;     micro-operation, and there are some latencies if data dependency occurs.
-+;;   MAC_RaRb
-+;;     A MAC instruction does multiplication at EX and does accumulation at MM,
-+;;     so the operand Rt is required at MM, and operands Ra and Rb are required
-+;;     at EX.
-+;;   ADDR_IN
-+;;     If an instruction requires an address as its input operand, the address
-+;;     is required at EX.
-+;;   ST
-+;;     A store instruction requires its data at MM.
-+;;   SMW(N, M)
-+;;     There are N micro-operations within an instruction that stores multiple
-+;;     words. Each M-th micro-operation requires its data at MM.
-+;;   BR
-+;;     If a branch instruction is conditional, its input data is required at EX.
-+
-+;; FPU_ADDR_OUT -> FPU_ADDR_IN
-+;; Main pipeline rules don't need this because those default latency is 1.

-+;;     An ALU-SHIFT instruction consists of a shift micro-operation followed
