Isn't that something you call "primitives"? When reading through some Intel 8086 the term "primitives" was mentioned when it came to such functions. > While the Z-80 had a lot of fancy features, though, the 6809, which came along > later, would have been significantly more powerful yet - as it had a hardware > *multiply* instruction, even if it wasn't crammed with as many bells and > whistles as the Z-80, most programs would run considerably faster on the 6809 as > a result of that. Isn't a 6809 considered an 8-bit CPU with a lot of 16-bit features? May be like a 68000 is a 16-bit CPU with some 32-bit features? -- Andreas My random toughts and comments https://news-commentaries.blogspot.com/
