FUNCTIONAL DESCRIPTION
CORE: Core module interconnects all the sub-modules in the Ctrl IP. Ports of core module are the top level ports for the Ctrl IP. AVSCLK clock is derived from i_clk based on prescaler value.
PRESCALER: Prescaler module is used to divide the system clock based on the given prescaler value to derive the serial clock input for AVSBus. It is recommended that system clock be at least 4 times the desired AVSBus clock speed.
CSR: CSR module has all the control and status registers. Command and response storing is modeled using 16 location memory for command and 16 location memory for response. It is possible to simplify and remove the memory.
FSM: FSM module generates the AVSBus transcations on AVSBus based on commands from CSR block. This blocks implements all the features of AVSBus specs. Following are different types of frames supported by FSM block particularly for AVSBus 2.0 commands
