Serial to Parallel data transfer in Design

Hi there i am a newbie and have been working with a simple vhdl component. I have attached this component(performs only xor operation on vectors) to a NIOS II processor designed using SOPC builder. The system module also includes input and output ports through which my component interacts with the processor. I am testing this by passing 32 bit vectors from the output port to the external xor component and read the result from the input port of the system module.

Now what i want to achieve is to be able to send 283 bit vectors to my vhdl component. The max lenght of an output port is 32 bits so i am unsure on how i could collect multiple data packets and send them in parallel to the component.

Could someone guide me on how this can be done. Would i require some VHDL or can the system module i developed using SOPC somehow create an interface(i.e. Burst Interace) that will allow me to send longer vectors to the external component?

Any help would be appreciated.

Thanks.
