OpenSPARC T1 v1.4 Specification Released

Posted by Bill Bradford on Mar 13, 2007

Version 1.4 of the OpenSPARC T1 specification has been released:

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.
