Q1:Fill the table

Q2:Posix threads

ROB trace single issue Assume the following: Ten ROB slots. 1 integer Execution unit, 2 reservation stations, one cycle to execute. 1 Floating Add Unit, 2 reservation stations, 10 cycles to execute. 1 Floating MULT Unit, 2 reservation stations, 15 cycles to execute. 1 Load unit with only two reservation stations Loads on hits require 2 clock cycles, both performed in the Load Unit. Functional units are pipelined! There is no forwarding between functional units; results are communicated by the common data bus (CDB). .The execution stage (EX) does both the effective address calculation and the memory access for loads and stores. Assume all memory l references are hits and branclh s are branch taken and are correct. loop: LD F0, 0 (R1) MULT F8 FO FO LD F4 1024 (R1) ADD F10 F10 F4 ADD F12 F12 FB DADDIU R1, R1, +8 BNE R1, R2, loop Fill in the table below for as much as you can assuming the BNE is taken and succeeds. (Do not add rows to the table.) Iter. Instruction Issues at Execute/me Write CDB Commit Comment Posix Threads: Take-Home question; emailed today, due Sunday night.
