Note that in the past the layout of E format has varied between floating point systems, so software should not have been written to depend on it being readable by other floating point systems. MIPS Technologies or any contractually-authorized third party reserves the right to change the information contained in this A.3 Floating Point Unit Instruction … R-Type Instruction Format Op : operation code (opcode) Specifies the operation of the instruction Also specifies the format of the instruction funct : function code – extends the opcode Up to 2 6 = 64 functions can be defined for the same opcode MIPS uses opcode 0 to define many R-type instructions Three Register Operands (common to many number. Thus all floating point instructions use opcode 010001. The instruction is broken up into fields of the same sizes as in the R-type instruction format. However, the fields are used in different ways. Most floating point intructions use the format field to specify a numerical coding format: single precision (.s), double precision (.d MIPS Technologies or any contractually-authorized third party reserves the right to change the information contained in this A.3 Floating Point Unit Instruction … Floating Point Instructions. The MIPS has a floating point coprocessor (numbered 1) that operates on single precision (32-bit) and double precision (64-bit) floating point numbers. 2.1.3 Format Field MIPS32™ Architecture For Programmers Volume II, and various floating point instruction formats, such as S, D, and PS • is used for the memory access types, such ascached and uncached 1.1.2 Bold Text • represents a term that is beingdefined CS61CFall%2013–%4–%Everything%isa%Number!%!
