Umm, the TX39 is 32-bit and does not have 64-bit instructions, so it can't have DMULT or DMULTU. > There is also the TX99 series (based on 25Kf): > https://www.toshiba.co.jp/about/press/2002_02/pr1901.htm Hmm, did the TX99 actually tape out? I thought the 25Kf was withdrawn and never made it to market. I only saw a couple of 25Kf LVs on Malta CPU daughtercards back in my MIPS UK days in mid 2000s. Maciej
