Re: [oc] FPU?

["Damjan Lampret" <lampret@opencores.org>]

Hi Long,

no official project yet. OR1K doesn't currently implement FPU nor does OR1K
ISA FP instructions. First current OR1K ISA should be extended with FP
instructions and later structural FPU implemented (probably best as separate
project under opencores but in a way that would allow easy integration with
basic OR1K processor). Iakovos Stamoulis developed a behavioral FPU but this
takes a lot of gates (FP addition takes as much as entire OR1001). Iakovos
said if he gets more time he will try to develop a structural one.

If you are interested to start a project, just say it.

regards, Damjan
