Exploration of the Power-Performance Tradeoff through Parameterization of FPGA-Based Multiprocessor Systems

Table 1

Different modules of the virtual-IO component together with their symbol and basic functionality.

Virtual-IO module	Symbol	Function
Virtual-IO 1		Sends data first to μB0 then to μB1. Receives data in the same order
Virtual-IO 2		Sends data only to μB0. Receives data only from μB1
Virtual-IO 3		Sends data first to μB0, then to both and finally only to μB1. Receives data first from μB0, then from μB1
Virtual-IO 4		Sends data only to μB0. Receives data only from μB0. Used for uniprocessor designs
Virtual-IO 5		Sends same data to both processors. Receives results only from μB0
Virtual-IO 6		Sends same data to both processors. Receives results only from μB1
