“…The thermal variations due to active electrical circuits within memory lowers the reliability of the MRR operation. Such a design calls for active thermal and power management in OPCM, which contributes to a power overhead of 10 − 30W [3]. Furthermore, using silicon-photonic links in combination with OPCM requires additional E-O and O-E conversions with this EPCM architecture that exacerbate the above discussed problems.…”

“…For a 2GB 4-bit OPCM array with 8 banks, a single bank consists of 1024 tiles with 32 cells/tile and a row and column of MRRs as shown in Figure 4b. 3 A bank, therefore, is composed of 1024 × 32 GSTs along a row/column with (1024 × 32 − 1) × 50nm of separation between GSTs, and a single row/column of MRRs at the beginning. Using the dimensions of these optical devices listed in Table IV, we calculate the area of a 2GB OPCM array and its bit density and report it in Table V.…”

“…With the growing requirements of chip computing performance and multitasking simultaneous processing capability, electrical networks-on-chip (ENoCs) cannot meet the needs of MPSoCs development due to the time delay, bandwidth, and power consumption problems [4]. Optical networks-on-chip (ONoCs), which can break through these bottlenecks, have been proven an effective method to solve the problems faced by ENoCs [5][6][7][8][9]. ONoCs combine both the characteristics of the electrical interconnect layer, which implements arbitration control, and the optical layer to transfer data [10][11][12].…”

“…Nonetheless, this technique for thermal tuning power consumption may negatively affect the bene ts of PNoC in terms of energy e ciency. In [13], a new frequency-align workload allocation policy, along with an Adaptive Frequency Tuning (AFT) policy, which can reduce the thermal power consumption of PNoCs, is presented. Frequency alignment uses thread allocation and thread migration to control the thermal, in order to match the photonic frequencies of the MRR loops in each photonic link.…”
