Does ISA ownership matter? A Tale of Three ISAs

December 22, 2020 Blog, News & Docs

An instruction set architecture (ISA) is crucial to the development of processors and their software ecosystems. Does ISA ownership matter? Let’s consider three proprietary ISAs and their history to find out.

Menta eFPGA and Codasip Announce Technology Partnership

December 7, 2020 News & Docs, Press Releases

Codasip announces a partnership with Menta S.A.S, a premier supplier of embedded FPGA solutions, enabling joint customers to modify processors in SoC after already manufactured. This will be possible by extending an existing processor with custom instructions in Codasip Studio and implementing these changes on Menta’s co-extended eFPGA cores.

Open Source vs Commercial RISC-V Licensing Models

November 26, 2020 Blog, News & Docs

Everybody is familiar with commercial licensing from traditional processor IP vendors. In discussing RISC-V, there is widespread confusion of terminology with RISC-V often being described as “open source”, often understood as “free”. But what is reality?

When Considering Processor PPA, Don’t Forget the Instruction Memory

November 12, 2020 Blog, News & Docs

The area of any part of a design contributes both to the silicon cost and to the power consumption, but a simplistic following of the “A” in a processor IP vendor’s PPA numbers can be misleading. What do you need to know?

What is needed to support an operating system?

October 15, 2020 Blog, News & Docs

For each embedded product, software developers need to consider whether they need an operating system; and if so, what type of an OS. Operating systems vary considerably and the choice of one for your processor core has important implications. Let us explore them.

Creating Domain-Specific Processors Using Custom RISC-V ISA Instructions

September 23, 2020 News & Docs, Whitepapers

The RISC-V ISA is designed in a modular way, meaning that the ISA has several groups of instructions (ISA extensions) that can be enabled or disabled as needed. This allows implementing precisely the instruction groups that the domain needs, without having to pay for area or power that will not be used.

What is processor core complexity?

September 10, 2020 Blog, News & Docs

Looking at any processor IP, you will find that their vendors emphasise PPA (performance, power & area) numbers. In theory, they should provide a level playing field for comparing different processor IP cores, but in reality, the situation is more complex. Let us consider performance.
