SuperKEKB electron-positron asymmetric collider is being constructed after a decade of successful operation at KEKB for B physics research. KEKB completed all of te technical milestones, and had offered important insights into te flavor structure of elementary particles, especially te CP violation. Te combination of scripting languages at te operation layer and EPICS at te equipment layer had led te control system to successful performance. Te new control system in SuperKEKB will continue to employ those major features of KEKB, with additional technologies for te reliability and flexibility. Te major structure will be maintained especially te online linkage to te simulation code and slow controls. However, as te design luminosity is 40-times higher than that of KEKB, several orders of magnitude higher performance will be required at certain area. At te same time more controllers with embedded technology will be installed to meet te limited resources.

J-PARC accelerator complex comprises Linac, 3-GeV RCS (Rapid Cycle Synchrotron), and 30-GeV MR (Main Ring). Te J-PARC is a joint project between JAEA and KEK. Two control systems, one for Linac and RCS and another for MR, were developed by two institutes. Both control systems use te EPICS toolkit, thus, inter-operation between two systems is possible. After te first beam in November, 2006, beam commissioning and operation have been successful. However, operation experience shows that two control systems often make operators distressed: for example, different GUI look-and-feels, separated alarm screens, independent archive systems, and so on. Considering demands of further power upgrade and longer beam delivery, we need something new, which is easy to understand for operators. It is essential to improve reliability of operation. We, two control groups, started to discuss future directions of our control systems. Ideas to develop common GUI screens of status and alarms, and to develop interfaces to connect archive systems to each other, are discussed. Progress will be reported.

A low-level RF controller has been developed for te accelerator controls for SuperKEKB, Super-conducting RF Test facility (STF) and Compact-ERL (cERL) at KEK. Te feedback mechanism will be performed on Vertex-V FPGA with 16-bit ADCs and DACs. Te card was designed as an advanced mezzanine card (AMC) for a MicroTCA shelf. An embedded EPICS IOC on te PowerPC core in FPGA will provide te global controls through channel access (CA) protocol on te backplane interconnect of te shelf. No other mechanisms are required for te external linkages. CA is exclusively employed in order to communicate with central controls and with an embedded IOC on a Linux-based PLC for slow controls.
