Flash Memory System
|HOME : RESEARCH : 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 22.214.171.124 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.
