Without hesitation, you lowered yourself between Bucky’s legs, licking your way across his abdomen, following the V line of his muscles with your tongue. You had your eyes locked on the two of them as you stalked over to the bed, finally getting to taste your boyfriend. A quick gasp escaped his lips as his back touched the bed, but Bucky instantly silenced him with a heated kiss. You caught him by surprise, and he stumbled backwards, falling on the sheets next to Buck. A simple, raspy “Steve” was all you could manage to say, before you gently pushed him in the direction of the bed. He took in a sharp breath before he latched his lips to one of your nipples, cautiously nibbling on it. You let out a small whimper as he opened your bra, finally freeing your breasts. You finally found that one spot, showering you with pleasure and you couldn’t stop a moan to escape your own lips – silencing the sounds from the bedroom in an instant.Ī small bite to your neck brought your attention back to the other super soldier currently wrapped around you. You shut your eyes, your finger slowly curling inside you as your boyfriend continued to make some of your favorite sounds. The moment Steve lowered his lips to Bucky’s tip, licking across it, Buck threw his head back, growling. You fingers reached your swollen clit, slowly rubbing circles with your thumb while your index travelled further, pushing deep inside you. As you watched them, you mirrored Steve’s every move with your own hand across your body, touch as light as a feather on your skin, slowly making its way to your heated core. He traced the insides of his left thigh with his tongue, earning a deep groan. Pleasure written all over his face, as Steve’s trail of kisses finally reached its end between your lover’s legs. You saw Bucky tilting his head, biting down on his bottom lip while his eyes were shut. We conclude that 1+1 protection is ideally suited for use in mixed-critical systems with high safety requirements.Steve began to kiss his way along Bucky’s jaw, peppering his pecs with kisses, eager to reach his destination. At the same time, 1+1 protection, on average, only causes a 1.18% earlier saturation rate for BE traffic, which we consider to be affordable. We give a comprehensive trade-off analysis of three protection switching schemes-1: n, 1:1, and 1+1-and show that 1+1 protection has less than half the worst case latency for critical traffic that 1: n and 1:1 protection have. Results show, that spreading out the critical traffic rather than naively dividing the system in critical and non-critical application domains is advantageous or even necessary in many cases and can allow for up to 13% more BE traffic. We then explore different channel and task mapping strategies for critical applications which use protection switching and evaluate the effect these mappings have on the best-effort (BE) traffic in the system.
We give synthesis results for the hybrid NoC, including the network interface, and show that our router uses over 32% fewer LUTs and registers than a competitive state-of-the-art router for mixed-critical MPSoC. In this paper, we present an FPGA implementation of such a NoC with all its features.
In previous work, we proposed the combination of protection-switching with a hybrid Time-Division-Multiplexed (TDM) and packet-switched Network-on-Chip (NoC) to achieve all three goals. Communication infrastructures designed for mixed-critical MPSoCs must provide isolation of traffic, hard real-time guarantees, and fault-tolerance.
