Flash Memory System

1. An FPGA-based development platform for SSD

- Designed as an open framework for designing, implementing, and evaluating HW/SW components for SSDs


- Delivering performance comparable to commercially available SSDs


2. BlueSSD hardware

- Built on top of the Xilinx XUPV2P FPGA board and the custom flash storage daughter board which holds up to 8 packages and up to 16 chip-enables.


- Populated with 32 1GB MLC flash parts, each with a single chip enable.


- PowerPC 405 on the XUP board runs the Linux kernel that is used as a platform for firmware such as a flash translation layer.




3. BlueSSD software

- Provide a flexible software infrastructure so that several flash management schemes can be employed with minimal modifications to the existing software system.


- Overall structure of the flash firmware, which is composed of 3 layers: a device driver for the flash controller, a host interface, and a flash translation layer.
