Quad core IP platform with integrated Arm security subsystem

Overview

Key Features

• Each ASIC is based on a CPU cluster for general purpose tasks and an AI cluster for neural network tasks with supporting memory and interfaces. The CPU cluster of Arm® CPU cores, nominally 4, provide a powerful processing capability by using either an Arm A53 or A55 with 9 - 10 GMIPS at 1 GHz nominal. The Neural Net cluster is based on either Arm Ethos cores or DSP-AI cores providing nominally 4 TOPS performance. Custom AI cores can be integrated as an alternate if required.
• The chip design has a composable Network on Chip system fabric, multi-path, multi-width (64b to 512b) data path at a nominal 800MHz. There is performance optimisation of the data flow for application, QoS arbitration and scheduling support. The System Management Subsystem (SMS) manages the configuration, start-up (Boot) and operation modes of the SoC along with active power management for low or battery powered applications.
• The integral security subsystem uses either an Arm A53 or M33, as the application demands, to provide activity/intrusion monitoring, software signing and crypto, and authentication to resist hacking, which is further enhanced by watchman behaviour tracking and deviation detection.

Benefits

• The SFA 200 design just needs the customer’s own IP or application-specific, off-the-shelf IP to create the final ASIC thus providing a low risk, faster time to market that can reduce design costs by up to 30%. To further reduce risk and time to market, Sondrel offers a full turnkey service that turns designs into fully tested, shipping silicon.
