PROCESSOR SUB-CARD, POWER BOARD ADAPTED TO PROCESSOR SUB-CARD, AND SYSTEM BOARD

摘要

A processor sub-card (10), a power board (30) adapted to same, and a system board (20). The processor sub-card (10) comprises: a sintering socket (104), a complex programmable logic device (CPLD) (102) and a read only memory (ROM) (103), a boundary scanning signal pin of the CPLD (102) being connected to the sintering socket (104), the ROM (103) being connected to the CPLD (102), and the sintering socket (104) controlling a boundary scanning signal of the CPLD (102) to complete sintering of the CPLD (102) and/or the ROM (103). The problems in the related art that a CPLD logic version and ROM firmware version of a processor small-system module are inconvenient to update and that the processor small-system module is inconvenient to arrange, maintain and repair are solved.
