A Middleware Approach to Achieving Fault Tolerance of Kahn Process Networks on Networks on Chips

Figure 10

The communication and computational overhead due to the proposed middleware for the JPEG encoder/decoder case study.

(a) Overhead in the total data transferred in the network due to proposed middleware with varying sizes (in bytes) of the data type of tokens

(b) Overhead in the execution time due to proposed middleware with varying sizes of KPN queues (tokens of 8 bytes)
