An apparatus and method of time keeping for a non-real-time OS is provided. The apparatus includes a processor and a Field Programmable Gate Array (FPGA). The processor requests performance of a Dual-Port Random Access Memory (DPRAM) read/write (R/W) operation in a DPRAM R/W time interval in a Time Division Multiple Access (TDMA) scheme using a system clock. Upon receipt of the DPRAM R/W operation performance request from the processor, the FPGA compares the operation performance request time with an access time table defining a DPRAM R/W time interval for each processor, generated in the TDMA scheme using the system clock. The FPGA performs the operation requested by the processor when the operation performance request has been made in the DPRAM R/W time interval of the processor.
