32 The device and principle of operation L-502.
signal processor. The interface of the processor with the computer is through the HOST port of the
DMA processor.
The signal processor has 32 MB SDRAM (L-502-P-

When the computer's power is turned on, before the BIOS of the computer starts initializing
the devices, the L-502 will download the firmware to the FPGA from Flash memory (
fig. 3-5
), and
the L-502 internal power supply system will be fully turned on. In this case, the option of loading
the main/backup firmware will depend on the status of the backup boot jumper (sec.
2.1.1
).
After loading the FPGA, the L-502 becomes a PCI Express device, which will be assigned the
appropriate system resources when the OS is initialized.
