For the first tape out of nanosoc, the instruction memory was implemented using SRAM. Whilst this meant that the read bandwidth from this memory was very fast. It also meant that on a power-on-reset, all the code was erased as SRAM is volatile memory. An alternative use of non-volatile memory would benefit applications where  deployment of the ASIC does not allow, or simply time is not available for programming the SRAM after every power up. 

The Arm Cortex-M55 AIoT SoC design platform is an AIoT subsystem that allows custom SoC designers to integrate their hardware circuits and embedded software for differentiation. The platform is developed by TSRI (Taiwan Semiconductor Research Institute) to support academic research on SoC design. It's built on the Arm Corstone-300 reference package, featuring the Cortex-M55 CPU and Ethos-U55 NPU.

There has been much request within the SoC Labs community for an Arm A-Class SoC that can support a full operating system platform, undertake more complex compute tasks and enable more complicated software loads. The Cortex-A53 is Arm's most widely deployed 64-bit Armv8-A processor and can provide these capabilities with power efficiency

This project aims to design and implement a high capacity memory subsystem for Arm A series processor based SoC designs.  The current focus of the project is the design and implementation of a Memory Controller for DDR4 memory. 

The Synopsys HAPS® System adds additional capabilities to the FPGA-based prototyping environments SoC Labs can use to support projects. The HAPS® system provides a greater amount of logic resources supporting development of larger SoC designs. It can be used to support multiple projects simultaneously. It is used by many semiconductor companies, including arm for their CPU verification. This collaboration project will use the HAPS® system in SoC Labs projects and share with the community experience in utilising such systems.

This collaboration project is aimed at providing specific tailored activities to the local geography in Canada by developing local actions that will help stimulate academics and their institutions and the broader semiconductor industry supporters to create new and exciting SoC design projects. 

It may include holding specific local physical meetups where people can exchange design ideas.

It may include utilising locally provided routes to fabrication.

It may include sharing hard to locate test capability across academic institutions.

On-chip SRAM in ASICs can use a significant area, which equates to a significant cost. One solution is to make the memory off-chip. This project explores the use of Arm IP to create an SRAM chiplet design. The benefit  is that standard memory chiplets can be fabricated at lower cost and used across multiple projects, miminising silicon area to the unique project needs.

Project Overview:

Our innovative SoC design for precision agriculture revolutionizes field management by deploying a robust mesh network of sensor-based devices, capable of detailed monitoring and swift response to variations in soil health, erosion, drought, and pest activities. This system not only ensures reliability through its mesh architecture—eliminating single points of failure—but also incorporates diverse sensors for comprehensive data acquisition. It's engineered for energy efficiency to sustain operation throughout an entire crop season, significantly optimizing resource use and reducing waste.
