I'd recommend one of the following two books
	See MIPS Run by Sweetman
or	Misc RISC Architecture by Kane/Heinrich.

The R4000 micorporcessor user's manual provides an excellent degree of 
detail, but can be hard to approach.  The MIPS Programmer's Reference
by Farquhar and Bunce is good as far as it goes, but I found it to be
somewhat dated and of limited use.

However, Nishimura-san's knowledge on the subject can be better than
all those books put together.  The paper books make a good reference
for when he's unavailable.
