چکیده

Network on Chip (NoC) is an enabling methodology of integrating a very high number of intellectual property (IP) blocks in a single System on Chip (SoC). A major challenge that NoC design is expected to face is the intrinsic unreliability of the interconnect infrastructure under technology limitations. Research must address the combination of new device-level defects or error-prone technologies within systems that must deliver high levels of reliability and dependability while satisfying other hard constraints such as low energy consumption. By incorporating novel error correcting codes it is possible to protect the NoC communication fabric against transient errors and at the same time lower the energy dissipation. We propose a novel, simple coding scheme called Crosstalk Avoiding Double Error Correction Code (CADEC). Detailed analysis followed by simulations with three commonly used NoC architectures show that CADEC provides significant energy savings compared to previously proposed crosstalk avoiding single error correcting codes and error-detection/ retransmission schemes.

Optimal low-power coding for error correction and crosstalk avoidance in on-chip data buses

Coupled switched capacitance causes crosstalk in ultra deep submicron/nanometer VLSI fabrication, which leads to power dissipation, delay faults, and logical malfunctions. We present the first memoryless transition bus-encoding technique for power minimization, errorcorrection, and elimination of crosstalk simultaneously. To accomplish this, we generalize balanced sampling plans avoiding adjace...

Coding for Reliable On-Chip Buses: A Class of Fundamental Bounds and Practical Codes

A reliable high-speed bus employing low-swing signaling can be designed by encoding the bus to prevent crosstalk and provide error correction. Coding for on-chip buses requires additional bus wires and codec circuits. In this paper, fundamental bounds on the number of wires required to provide joint crosstalk avoidance and error correction using memoryless codes are presented. The authors propo...

Joint Crosstalk-Avoidance and Error-Correction Coding for Parallel Data Buses

Decreasing transistor sizes and lower voltage swings cause two distinct problems for communication in integrated circuits. First, decreasing inter-wire spacing increases interline capacitive coupling, which adversely affects transmission energy and delay. Second, lower voltage swings render the transmission susceptible to various noise sources. Coding can be used to address both these problems....
