DDR3 System On-and-Around the Chip

by Jim Turley

We saw the other day that Cadence was being aggressive with the memory controller IP from their Denali side. They’re actually trying to create a wider-scoped solution by providing a PCB package that ties in well with their DDR3 memory controller IP.

DDR memory timing is simply nuts, and board layout is critical. Everything matters. So the DDR3 Design-in kit contains the memory controller I/O and IC package model, timing/duration model, connector model, memory model, DIMM topology, and electrical constraints for the controller and memory.

While it ties in well with their DDR3 controller IP, it’s modular enough to detach that and still be of use with someone else’s controller IP.

Quantized Neural Networks for FPGA Inference

Sponsored by Intel

Implementing a low precision network in FPGA hardware for efficient inferencing provides numerous advantages when it comes to meeting demanding specifications. The increased flexibility allows optimization of throughput, overall power consumption, resource usage, device size, TOPs/watt, and deterministic latency. These are important benefits where scaling and efficiency are inherent requirements of the application.
