Overview

Providing a Complete Solution for HBM4

The Cadence High-Bandwidth Memory generation 4 (HBM4E) PHY is optimized for systems that require the highest-bandwidth, low-latency memory solution. The memory subsystem consisting of PHY and controller supports data rates up to 12.8Gbps per data pin, featuring 32 independent channels, for a total data width of 2048 bits. The PHY is designed for a 2.5D system with a silicon interposer to route signals between the 3D DRAM stack and PHY. 

The fourth-generation design is optimized for low power consumption and low PHY area. Cadence provides the complete solution including PHY, controller, interposer, and package.

High Bandwidth Memory Evolution from First Generation HBM to the Latest HBM4

HBM4 is the latest generation of the High Bandwidth Memory (HBM) that has become analogous to the Artificial Intelligence (AI) boom that is everywhere in today’s world. HBM is also increasingly being used in other applications like Data centers, autonomous driving systems, servers, cloud computing just to mention few domains where bandwidth and performance in a key requirement.

The Memory Imperative for Next-Generation AI Accelerator SoCs

AI accelerators are key components of the AI data center tasked with speeding up the complex mathematical calculations required for AI and machine learning (ML). As the demand for AI continues to skyrocket, it’s crucial that SoCs provide the necessary “brain power” for these AI accelerators to keep pace.

Heterogeneous Multicore using Cadence IP

This blog presents a heterogeneous multicore system built with the RISC-V Host CPU and Cadence IP: Xtensa DSPs, and the Janus Network-on-Chip (NoC). While this example uses an RISC-V CPU, any other ISA with similar capabilities can also serve as the host CPU.
