OpenSPARC T1 v1.4 now available for download
Hello everyone,
OpenSPARC T1 v1.4 is not available for download. Here is a short description of available new features. Please do download and try it out.
New features in OpenSPARC v1.4
==============================
OpenSPARC T1 v1.4 adds significant new functionality as well as new
platform support in its hardware bundle. On the design side, it adds
knob to create single core, single thread implementation of the
OpenSPARC T1. This, we believe, will be useful in creating multi-core
designs that do not include hardware threading. Additionally, it also
provides an option to create FPGA implementation from the base
design. This FPGA option creates a fully synchronous design with
better utilization of on-chip FPGA resources like Block RAMs and
Multipliers. And finally, version v1.4 also includes an option to
remove Stream Processing Unit (SPU) from the design. Since SPU is
essentially an on-chip hardware accelerator for cryptographic
functions, one can choose to remove it for more general purpose CPU
implementations.
Although three options described above can be chosen independent of
each other, combining them will create an FPGA implementation with the
smallest possible area foot-print. Needless to say, we have also
included verification environment for the new additions and also added,
for the first time, elementary support for netlist verification through
vector playback.
Together with design enhancements, OpenSPARC T1 v1.4 also supports
x86_64 hardware platform.
For more details, please check the "OpenSPARC T1 Processor Design and
Verification User's Guide" included under to "doc" directory of the
hardware distribution.
