Dear All, I try to develop a gcc based compiler (I am beginner to gcc) for very simple m assively parallel processing (MPP) system. So, I consider the RTL to MD part in now.
Anyone know a site about introduction to the part (focusing to the MPP), excep ting for gcc internal site. I want to develop is as follows; ---- 1) Processing Elements (PEs) PE has an ID (ID), 2-word Instruction Register (IR), 1-word Data Register (DR), 2 input-operands (OPR-1&2), note OPR-1&2 is ID or immediate (IMM), Operation: DR <= IR(OPR-1(DR), OPR-2(DR)); operation is defined by IR, 2) Memory Elements (MEs) ME has an ID (ID), 2-word Instruction Register (IR), 1-word Data Register (DR), 2 input-operands (OPR-1&2), note OPR-1&2 is ID or immediate (IMM), Load Operation: DR <= Mem[IR(OPR-1(DR), OPR-2(DR))] operation is defined by I R, Store Operation: DR => Mem[IR(OPR-1(DR), OPR-2(DR))] operation is defined by I R, 3) Instruction Format IR[63:48]: ID of PE (sink or source for store) IR[47:32]: etc IR[31:16]: ID/IMM of OPR-1 IR[15:0]: ID/IMM of OPR-2 Best Regards, Shigeyuki Takano
