Perseus Labs tests the following CPU architecture.
SPARC SPARC (Scalable Processor ARChitecture)
is a pure big-endian RISC microprocessor architecture originally
designed in 1985 by Sun Microsystems. SPARC is a registered trademark
of SPARCInternational, Inc.,
an organization established in 1989 to promote the SPARC and to provide
conformance testing. SPARC International was intended to "open" the
SPARC architecture to make a larger ecosystem for the design, which has
been licensed to several manufacturers, including Texas Instruments,
Cypress Semiconductor, and Fujitsu. As a result of SPARC International,
the SPARC architecture is fully open and non-proprietary: there's a
fully open source implementation called LEON, written in VHDL. Its
source code is available under the LGPL.
