8.2.7 Saturation operation instructions
[Instructions]
SATADD, SATSUB, SATSUBI, SATSUBR
[Pipeline]
[Description]
The pipeline consists of 5 stages, IF, ID, EX, MEM, and WB. However, no operation is performed
in the MEM stage, because memory is not accessed.
8.2.8 Branch instruction
(1) Conditional branch instructions
[Instructions]
Bcond instructions (BGT, BGE, BLT, BLE, BH, BNL, BL, BNH, BE, BNE, BV, BNV, BN, BP,
BC, BNC, BZ, BNZ, BSA): Except BR instruction
[Pipeline]
(a) When the condition is not realized
(b) When the condition is realized
IF
×
: Instruction fetch that is not executed
ID
×
: Instruction decode that is not executed
[Description]
The pipeline consists of 5 stages, IF, ID, EX, MEM, and WB. However, no operation is performed
in the MEM and WB stages, because memory is not accessed and no data is written to registers.
(a) When the condition is not realized
The number of execution clocks for the branch instruction is 1.
(b) When the condition is realized
The number of execution clocks for the branch instruction is 3. IF stage of the next
instruction and next to next instruction of the branch instruction is not executed.
