Hower aka Kudzu http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2840 http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2840 We dont need 486. For x86, we can safely assume min level of P3.

Embedded systems are going ARM. In addition if we go 486 we need to support AT Bus , PIC ( Fri, 20 Nov 2009 01:31:42 GMT Ben Kloosterman http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2837 http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2837 In C there is often a compile option to treat doubles as floats for extra performance.

For that I say X87 for now, as using SSE2 is Thu, 19 Nov 2009 13:41:03 GMT john_cena87_2004 http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2833 http://tech.groups.yahoo.com/group/Cosmos-Dev/message/2833 well, so are you telling we must write both software, x87 and SSE(2) implementation and choose it by builder?

However SSE advantages are not fully utlized, like packed calculation..even if there are those opcodes. Should we use it? ... Da: john_cena87_2004
