Bus Convertors
Overview
The bus converter module transforms 64-bit wide initiator data buses to smaller 32-bit target data buses or vice-versa. The downsizer module cuts the width of the data channel in half as it transitions from initiator to slave. You can do full-width initiator transfers. This method comprises changing the transfer type, burst, and size, as well as latching half of the initiator read data. Furthermore, several target write or read operations may be necessary to transport data to and from the narrow target. Other width converters are also available for a variety of buses.
Key Features
- AXI
- Types
- A narrow target on a wide bus
- A target module developed for a 32-bit bus can be converted to a 64-bit bus. This technique can be applied to hard macrocells as it only requires external logic and no internal design changes.
- 32-bit wide initiator data buses to larger 64-bit target data buses
- 64-bit wide initiator data buses to larger 128-bit target data buses
- A wide target on a narrow bus
- Target modules built for 64-bit data buses can be changed to 32-bit buses. This technique can be applied to hard macrocells as it only requires external logic and no internal design change
- 64-bit wide initiator data buses to smaller 32-bit target data buses
- 128-bit wide initiator data buses to smaller 32-bit target data buses
