LCLS-II's high beam rate of al­most 1MHz and the re­quire­ment that sev­eral "high-per­for­mance" sys­tems (such as MPS, BPM, LLRF, tim­ing etc.) shall re­solve in­di­vid­ual bunches pre­cludes the use of a tra­di­tional soft­ware based con­trol sys­tem but re­quires many core ser­vices to be im­ple­mented in FPGA logic. SLAC has cre­ated a com­pre­hen­sive open-source firmware frame­work which im­ple­ments many com­monly used blocks (e.g., tim­ing, glob­ally-syn­chro­nized fast data buffers, MPS, di­ag­nos­tic data cap­ture), li­braries (Eth­er­net pro­to­col stack, AXI in­ter­con­nect, FIFOs, mem­ory etc.) and in­ter­faces (e.g., for tim­ing, di­ag­nos­tic data etc.) thus pro­vid­ing a ver­sa­tile plat­form on top of which pow­er­ful high-per­for­mance sys­tems can be built and rapidly in­te­grated.

  The LCLS-II fa­cil­ity cur­rently under con­struc­tion at SLAC will be ca­pa­ble of de­liv­er­ing an elec­tron beam at a rate of up to al­most 1MHz. The BPM sys­tem (and other di­ag­nos­tics) are re­quired to ac­quire time-stamped read­ings for each in­di­vid­ual bunch. The high rate man­dates that the pro­cess­ing al­go­rithms as well as data ex­change with other high-per­for­mance sys­tems such as MPS (ma­chine-pro­tec­tion sys­tem) or bunch-length mon­i­tors are im­ple­mented with FPGA tech­nol­ogy. Our BPM-pro­cess­ing firmware builds on top of the SLAC "com­mon-plat­form" [*] and in­te­grates tightly with core ser­vices pro­vided by the plat­form such as tim­ing, data-buffer­ing and com­mu­ni­ca­tion chan­nels.
