;; 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
;;     is ready at MM.
;;   DIV
;;     Compute data in the divider and produce the data. The result is ready
;;     at MM.
;;
;; 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.
