This makes the whole system latency sensitive. So we need low latency, but we also need very high throughput: A recurring theme in IDS/IPS literature is the gap between the workloads they need to handle and the capabilities of existing hardware/software implementations. The target FPGA for Pigasus has 16MB of BRAM.

Making queries to an inference engine has many of the same throughput, latency, and cost considerations as making queries to a datastore, and more and more applications are coming to depend on such queries. The following figure highlights how just one of these variables, batch size, impacts throughput and latency on ResNet50.

High Scalability

MARCH 1, 2019

It's HighScalability time: 10 years of AWS architecture increasing simplicity or increasing complexity? It was made possible by using a low latency of 0.1 seconds, the lower the latency, the more responsive the robot. Michael Wittig ). Do you like this sort of Stuff?

The art and science of microprocessor architecture is a never-ending struggling to balance complexity, verifiability, usability, expressiveness, compactness, ease of encoding/decoding, energy consumption, backwards compatibility, forwards compatibility, and other factors. This includes Haswell and newer cores.
