;; LSU 2 stage pipelined
;; FPU 3 stage pipelined
;; It also has 4 vector units, one for each type of vector instruction.
;; However, we can only dispatch 2 instructions per cycle.
;; Max issue 3 insns/clock cycle (includes 1 branch)
;; In-order execution
;; Branches go straight to the BPU. All other insns are handled
;; by a dispatch unit which can issue a max of 3 insns per cycle.
