The invention provides a method for parallelly executing instructions of very long instruction words in the technical field of electronic, which comprises the following steps: acquiring a very long instruction word packet; judging whether a current instruction can be parallelly executed with a next instruction according to the number of a functional unit corresponding to each instruction in the word packet; and executing each instruction according to the judgment result. The embodiment of the invention also provides a device for parallelly executing instructions of very long instruction words. The method judges whether the current instruction can be parallelly executed with the next instruction according to the number of the functional unit, solves the problem of low coding efficiency because extraneous information of the instruction is needed to indicate that a plurality of instructions are parallelly executed in a plurality of functional units, reduces parallel indicating bits, enlarges coding space and reduces memory space occupied by parallelly executed information in the whole instruction.
