Chisel (an acronym for Constructing Hardware in a Scala Embedded Language [1]) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level. [2] [3] Chisel is based on Scala as a domain-specific language (DSL).
Other tools instead operate at a higher level of abstraction and allow to synthesize HDL code starting from languages like Chisel or SpinalHDL. The higher abstraction of such languages enables formal verification of HDL code. [10] [11] [better source needed]

Approaches based on standard C or C++ (with libraries or other extensions allowing parallel programming) are found in the Catapult C tools from Mentor Graphics, and the Impulse C tools from Impulse Accelerated Technologies. A similar initiative from Intel is the use of Data Parallel C++, related to SYCL, as a high-level synthesis language.
The Dadda multiplier is a hardware binary multiplier design invented by computer scientist Luigi Dadda in 1965. [1] It uses a selection of full and half adders to sum the partial products in stages (the Dadda tree or Dadda reduction) until two numbers are left.
"I think I was only there the first day. Maybe I made it to day two," she added. "We did the read-throughs and they staged it, and then they're like, we better get somebody else."
RISC-V [b] (pronounced "risk-five" [2]: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. . The project began in 2010 at the University of California, Berkeley, transferred to the RISC-V Foundation in 2015, and on to RISC-V International, a Swiss non-profit entity, in November 20
