Articles

In this article we’ll look at some of the more widely used: the OpenRISC 1000 from OpenCores, Gaisler’s LEON family, Lattice Semiconductor’s LM32 and Oracle’s OpenSPARC, as well as more bleeding edge research designs such as BERI and CHERI from Cambridge University Computer Laboratory.

We’ll consider the technology, the business case, the engineering risks, and the licensing challenges of using such designs.

This paper presents an analysis of the energy consumption of an extensive number of the optimizations a modern compiler can perform, and it was published in The Computer Journal, November 2013.

The abstract and a PDF copy of the paper can be found on the Oxford Journals website.
