Azadi - آزادی means "The Freedom", this System on a Chip (SoC) is the start of many RISC-V based SoCs to come. It is the Final Year Project (FYP) of our MERL Research Interns i.e Zeeshan Rafique, Sajjad Ahmed, Muhammad Waleed Waseem and Usman Zain ul Abideen as a part of their Bachelor's Degree requirement. Azadi is an SoC with a 32-bit RISC-V signal core extended version of ibex we named it "buraq", it is a 3-stage pipeline core that implements the RV32IMFDC instruction set architecture, a limited number of peripherals UART, SPI, GPIO, PWM, and timer. It also contains a Software Development Kit (SDK) for rapid development, debugging and testing.

We are preparing to move forward after the tape-out of the SoCs. We aim to add another extension known as the Vector Extension (short:' V') to our core. This will accelerate our processing speed for complex machine algorithm. We hoped that a low-level virtual machine (LLVM) will provide the opportunity for us to write an inline vector extension assembly. We are forming a team that is solely exploring an LLVM. Another work that is in progress is the optimization of CHISEL generated Verilog which is generated by FIRRTL. Usually, the CHISEL generated Verilog is not much readable the naming convention is not understandable by the observer so for tackling this problem the subset of the students is working on that.

Rocket chip is the SoC generator written in Chisel and understood by quite a few. We make our own pedagogy which enabled our undergraduate students to understand this complex and powerful tool and its architecture which is not well documented and is a pain problem for many industries looking to adopt Chisel and RISC-V. Our goal is to Reverse Engineer the Rocket Chip generator by using the expertise of Scala (functional Programming and Object Oriented Programming).
