We controlled main equipment of the accelerator used Epics based control system at KEKB.We had stabilized operation and development in basics as the upper limit, and Epics3.13, the CPU(PPC 6750) which we used from startup time now.However, the speedup of the network and the speedup of the CPU advanced, and the part that cannot correspond under the present conditions has become a problem gradually.Therefore, the necessity of Epics and CPU upgrade has gradually risen to us. We started developpment including upgrade CPU with PPC-MVME5500 and Epics with 3.14 form 2006 at KEKB.We have succeeded in the VME control by CPU PPC-MVME5500 which carried VXI, Trigger Reciver, PVME501, advme1522, Camac so far.We were realized fiveplaces of operation at present KEKB.In addition, the replacement is scheduled to be advanced as upgrade of CPU and Epics in the future based on the result. Here, this reports on the present status and upgrade of VME computer at KEKB.
