FALC56 E1/T1/J1 Framer; Intel Bus Interface (HPI) to SPI bridge via FPGA

Hi, I'm looking for an Intel Microprocessor 8-bit bus interface converter/bridge to SPI that I'll implement at the FPGA in order to convert the FALC56 bus to another system SPI communication. Also,...

Hi,


I am unsure on your request here, are you looking for a soft or hard processor for your system?


In our Platform Designer in Quartus, our PD will auto add a bridge to satisfy any mismatch bus address width in your Qsys design, but we need more info on what you're trying to achieve.

Hi,

We are using FALC56 E1/T1/J1 PEF2256 (full p/n: PEF2256EV22), Intel's component.

On the datasheet, I noticed this component is known to use "Intel Microprocessor 8-bit bus interface".

I'm looking for an "Intel Microprocessor 8-bit bus interface" to SPI converter (bridge) that I'll implement at my FPGA (VHDL).

This bridge should convert "Intel Microprocessor 8-bit bus interface" (parallel) to SPI (serial) and vice versa.

I'm asking here because I didn't find any pseudo code or examples on the internet regarding the "Intel Microprocessor 8-bit bus interface" protocol especially how to convert it to SPI.

Any documents, code examples, or even all the bridge code will help me a lot.
