Bord PCB FPGA

YCTECH industrial product control board development includes industrial control board software design, software upgrade, schematic diagram design, PCB design, PCB production and PCBA processing located in the east coast of China. Our company designs, develops and manufactures FPGA pcb board. iCore4 dual-core industrial control board is the fourth-generation iCore series dual-core board launched by the company; due to its unique ARM + FPGA "one-size-fits-all" dual-core structure, it can be used in many test measurement and control fields. When iCore4 is used in the core of the product, the "ARM" core acts as the CPU role (it can also be said to be a "serial" execution role), responsible for function implementation, event processing, and interface functions. As a "logic device" role (or "parallel" execution role), the "FPGA" core is responsible for functions such as parallel processing, real-time processing, and logic management. The two cores "ARM" and "FPGA" communicate using a 16-bit parallel bus. The high bandwidth and ease of use of the parallel bus ensure the convenience and real-time performance of the data exchange between the two cores, making the two cores "twisted into one rope" to cope with the increasing functions of test and measurement and automatic control products , Performance requirements.
