* @brief Red Pitaya symplified AXI slave.
*
* @Author Matej Oblak
*
* (c) Red Pitaya http://www.redpitaya.com
*
* This part of code is written in Verilog hardware description language (HDL).

/**
* GENERAL DESCRIPTION:
*
* AXI slave used also for simple bus master.
*
*
* /------\
* WR ADDRESS ----> | WR |
* WR DATA ----> | | -----------
* WR RESPONSE <---- | CH | |
* \------/ /--------\
* | SIMPLE | ---> WR/RD ADDRRESS
* AXI | | ---> WR DATA
* | RP | <--- RD DATA
* | BUS | <--- ACKNOWLEDGE
* /------\ \--------/
* RD ADDRESS ----> | RD | |
* RD DATA <---- | CH | -----------
* \------/
*
*
* Because AXI bus is quite complex simplier bus was created.
*
* It combines write and read channel, where write has bigger priority. Command
* is then send forward to red pitaya bus. When wite or read acknowledge is
* received AXI response is created and new AXI is accepted.
*
* To prevent AXI lockups because no response is received, this slave creates its
* own after 32 cycles (ack_cnt).

/**
* GENERAL DESCRIPTION:
*
* Clock domain bridge for system bus.
*
*
* /------\
* SYSTEM | | PROCESSING
* BUS <-----> | SYNC | <-----> BUS
* | |
* \------/
*
*
* System bus runs on one clock domain while processing runs on separate. To
* simplify transition of writing and reading data this bridge was created.
