2.1.2 Operation
The pipeline of the V
R
10000 has seven stages. The operation of each stage is described below:
(1) Stage 1 (fetch)
Four instructions are fetched in 1 cycle and stored to the instruction register.
(2) Stage 2 (decode)
The four instructions fetched in stage 1 are decoded.
(3) Stage 3 (issue)
The decoded instructions are written to a queue. The V
R
10000 has an FP queue, integer queue, and address
queue. In addition, an operand is read from the register file.
(4) Stage 4 through stage 6 (execute)
The instructions are executed. The execution pipeline and execution cycle differ depending on the type of
instruction.
(a) FP addition pipeline
Executes floating-point addition instructions in 3 PCycle.
(b) FP multiplication pipeline
Executes floating-point multiplication, division, and square root instructions in 3 PCycle.
(c) Integer ALU1 pipeline
Executes integer addition, subtraction, shift, and logic instructions in 1 Pcycle.
(d) Integer ALU2 pipeline
Executes integer addition, subtraction, and logic instructions in 1 PCycle.
(e) Load/store pipeline
Generates a memory address used for integer or floating-point load/store instructions.
(5) Stage 7 (store)
The results of executing the instructions are stored to registers.
