Abstract
Described herein is a method and system for accessing a block addressable input/output (I/O) device, such as a non-volatile memory (NVM), as byte addressable memory. A front end processor connected to a Peripheral Component Interconnect Express (PCIe) switch performs as a front end interface to the block addressable I/O device to emulate byte addressability. A PCIe device, such as a graphics processing unit (GPU), can directly access the necessary bytes via the front end processor from the block addressable I/O device. The PCIe compatible devices can access data from the block I/O devices without having to go through system memory and a host processor. In an implementation, a system can include block addressable I/O, byte addressable I/O and hybrids thereof which support direct access to byte addressable memory by the host processor, GPU and any other PCIe compatible device.
