TS-4200 FPGA
The TS-4200 features a Low power Actel FPGA clocked by the CPU only when needed. This FPGA is not end user programmable, but you can use the MUXBUS to allow communication to an offboard FPGA. The TS-4200 provides access to the FPGA in an 8 bit region and a 16 bit region. The 8 bit base address is 0x10000000. The 16 bit base address is 0x30000000. All registers inside the TS-4200 FPGA are 16 bit registers and should be accessed via the 16 bit space. The 8 bit space is only needed for off-board 8 bit devices on the MUXBUS. To access hardware cores in the FPGA, add the offset in the table below to the base address.
This table shows our top level decode for the FPGA. Use the 16 or 8 bit address with these offsets to talk to our various FPGA cores.
Offset | Usage |
---|---|
0x0 | Syscon registers |
0x080 | ADC registers (for off-board ADC) |
0x100 | NAND flash registers |
0x200 | NVRAM control registers |
0x400 | 1KB MUXBUS space |
0x800 | 2KB Direct blockram access (For NVRAM transfers) |
