+;; Producers (LHS)
+;; LD
+;; 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

+;; Consumers (RHS)
+;; ALU, MOVD44, PBSAD, PBSADA_RaRb, MUL, MAC, DIV, MMU
+;; 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.
