After attending RISC-V Summit 2026 in Bologna, Italy, we would like to thank all of you we had a chance to talk to.
At the summit we showed a demonstration of RISC-V / VSDSP interprocessor communications on our VSRVES01 CAT Board, using an equalizer with a web interface as the example. The demo code needs still to be polished, but when it is cleaned, the demo will be released with full source code for both the Linux/RISC-V and the VSOS/VSDSP side.
For discussions, you are welcome to participate at our VSDSP Forum.

The pricing of VS1073 has changed. The new price in quantities is now below VS1053, VS8053, VS1063, VS1163, and VS8063.

VS1073 is based on new technology which makes it less expensive to mass produce, and now it is priced accordingly. As it is using new technology, VS1073 is also likely to stay in production for a very long time, so it is ideal for new designs.

After this change VS1073, which has more features than any other VLSI Soluton's VS10X3 ICs, is firmly at a price optimum.

A new VS1003 variant, VS1003B-LK is now available to buy.

The new drop-in replacement for VS1003B-L has AuPdCu instead of gold wire bonding which makes its price significantly lower. The change doesn't affect specifications: they are exactly same for the new variant.

For the third year in a row, we will attend the RISC-V Summit, held this year in Bologna, Italy.

We will be at the Tristan booth where we will have demonstrations for our RISC-V / VSDSP hybrid IC VSRVES01, and the soon-to-come VSRVES02.

You are welcome to visit our booth and say hello!

The  VSRVES01 root files have been updated for VSOS 3.70.

• VSRVES01 root v3.70
• VSRVES01 solutions (source code)

VSRVES01 VSOS Kernel v3.70 is now available as a template for the new VSIDE v2.51.

This is the fourth and final release that makes almost all VSDSP source code for VSRVE01 available.

Next week there will be a document update to explain how to compile and modify all the code that has been made available during the last weeks.

Also the VSOS Root Image has been updated. The new version has a newer version of DDRLoad that allows for some DDR2 memories that have timings that are slightly outside the Jedec specification.

• Download VSIDE v2.51
• VSOS Root Image (2026-05-11)

The VSRVES01 VSDSP/VSOS Solutions package contains the source code for most VSOS device drivers and applications for the VSRVES01 IC.

The drivers and applications are provided as VSIDE Solutions, so if you have downloaded VSIDE 2.50 or higher, you can open these solutions and modify them at will.

This is the third of four releases that will make VSRVES01 VSDSP/VSOS source code available.
