Kosmodrom, is a direct collaboration with Globalfoundries for evaluating different library options of the GF 22FDX process using a realistic benchmark. For this purpose, there are two 64-bit RISC-V based Ariane cores with the latest updates and fixes (now with FPUs). One core has been optimized for high performance (1.3GHz typical) and the other one for extreme low power operation (300Mhz typical case operation) using different standard cell libraries and optimization corners. Several design iterations have been made with the guidance of experts from Globalfoundries to utilize different libraries with various operating conditions that also include body biasing.
The design also includes 1.25 MByte of SRAM memory to be used by the Ariane cores, an Adaptive Body Biasing block from Invecas, a small instance of our neurostream accelerator, as well as some test structures for electro-optical interfaces (eos32).
The name of the chip continues the space related naming conventions used with Ariane series of chips, and is the famous launch site for Soyuz rockets in Baikonur, in present day Kazakhstan. Technically the name could refer to any kind of spaceport, but in this case, we used it specifically for the spaceport in Baikonur. We also have a history of using the wrong names for Ariane based projects. Similar to us using stand-in (Lego) Saturn-V rockets in twitter messages on Ariane, no Ariane rocket was launched from Baikonur.
