| Summary: | The original trigger fast control (FC) protocols are still followed for the the DCT trigger upgarde, but with some additional FC commands and some modifications of implementation for the new DCT boards. For all old DCT boards TSF, BLT, PTD and the GLT, they all used a single FPGA (ORCA OR2C10) with identical firmware for the core FC logic. The same FC firmware is adopted with some minor modifications to the core FC code for the new ZPD and TSF, but this part of logic generally lives in a small part of a much larger Xilinx FPGA for the new boards. The “Op-control ” section which interprets the FC command for board specific communications have changed signifiantly from the old DCT implementation and also very different between TSF and ZPD. The updated FC command documentation and VHDL simulation results can be found at [1] and [2]. The changes to the fast control commands: • One major addition is the variable length block read and block write commands 1216 and 1316. The old FC commands for fixed length block R/W commands 1516 and 1616 are not supported for the new TSF,ZPD boards, while the new commands 12,13 will not work on any old DCT or GLT boards because the small ORCA FPGA hosting the |
