// description:
// 1. Dispatch unit receives uop instructions from uop queue
// 2. Dispatch unit check rules to determine if the uops are sent to reservation stations(RS). 
//    There are two ways to solve: 
//     a. stall pipeline
//     b. foreward data from ROB
// 3. Dispatch unit read vector data from VRF for uops.
// 
// feature list:
// 1. Dispatch module can issue 2 uops at most.
//     a. Uop sequence must be in-order.
//     b. Issuing uop(s) use valid-ready handshake mechanism.
// 2. Dispatch rules
//     a. RAW data hazard: 
//         I. uop0 Vs rob_entry(s). if rob_entry.vd_valid is 'b0, then stall pipeline (do not issue uop0)
//         II.uop1 Vs rob_entry(s). if rob_entry.vd_valid is 'b0, then do not issue uop1
//         II.uop1 Vs uop0. if uop0.vd_valid is the src of uop1, then do not issue uop0
//     b. Structure hazard:
//         I. the src-operand number of uops is more than 4, then only issue uop0
