Some formats don't have 11bits for opcode field, and in thiscase, bit field other than op are defined as 0s. For example, opcode of fma instruction which is RRR format is defined as 0x700,since 0x700 -> 11'b11100000000, this means opcode is 4'b1110, and other 7bits are defined as 7'b0000000.-=-=-= ASM_FORMAT =-=-=-RRR category RI7 category ASM_RRR mnemonic RC, RA, RB, RT ASM_RI4 mnemonic RT, RA, I4 ASM_RI7 mnemonic RT, RA, I7RI8 category RI10 category ASM_RUI8 mnemonic RT, RA, UI8 ASM_AI10 mnemonic RA, I10 ASM_RI10 mnemonic RT, RA, R10 ASM_RI10IDX mnemonic RT, I10(RA)RI16 category RI18 category ASM_I16W mnemonic I16W ASM_RI18 mnemonic RT, I18 ASM_RI16 mnemonic RT, I16 ASM_RI16W mnemonic RT, I16WRR category LBT category ASM_MFSPR mnemonic RT, SA ASM_LBT mnemonic brinst, brtarg ASM_MTSPR mnemonic SA, RT ASM_NOOP mnemonic LBTI category ASM_RA mnemonic RA ASM_LBTI mnemonic brinst, RA ASM_RAB mnemonic RA, RB ASM_RDCH mnemonic RT, CA ASM_RR mnemonic RT, RA, RB ASM_RT mnemonic RT ASM_RTA mnemonic RT, RA ASM_WRCH mnemonic CA, RTNote that RRR instructions have the names for RC and RT reversed fromwhat's in the ISA, in order to put RT in the same position it appearsfor other formats.-=-=-= DEPENDENCY =-=-=-DEPENDENCY filed consists of 5 digits. This represents which register is used as source and which register is used as target.The first(most significant) digit is always 0. Then it is followd by RC, RB, RA and RT digits.If the digit is 0, this means the corresponding register is not used in the instruction.If the digit is 1, this means the corresponding register is used as a source in the instruction.If the digit is 2, this means the corresponding register is used as a target in the instruction.If the digit is 3, this means the corresponding register is used as both source and target in the instruction.For example, fms instruction has 00113 as the DEPENDENCY field. This means RC is not used in this operation, RB and RA areused as sources and RT is the target.-=-=-= PIPE =-=-=-This field shows which execution pipe is used for the instructionpipe0 execution
