Section 8 Pipeline Operation
When a register (FPUL) that stores the result of a floating-point arithmetic operation instruction is
read (used as a source register) by a following STS instruction, and the value is output to the CPU,
latency is shortened by 2 cycles (figure 8.38).
The time required for the result of an FCMP instruction to be reflected in the T bit is 2 cycles in
the case of single-precision, and 3 cycles in the case of double-precision. As a result, if that
instruction (the following instruction) references the T bit, execution is delayed by the above slot
interval (figure 8.39).
When the FPSCR value is changed using an LDS or LDS.L instruction, execution of the next
instruction by a 3-slot interval (figure 8.40).
