GTX realizes physical layer of SATA protocol. Link layer and transport layers are implemented in VHDL with programmable logic resources. Application layer is developed on POWERPC440 embedded in Xilinx Virtex-5 FPGA. In order to test the performance of SATA controller PLB2SATAIP, an Embedded SATA Storage (ESS) reference system has been created in virtex 5 platform .The ESS reference system has been implemented in xilinx ML507 Evaluation Platform. The FPGA chip is XC5VFX70T.
The experiment results shows the maximal sustained sequential writes up to 215 MB/s and sustained sequential reads up to 273MB/s .( Intel Solid-State Drive 320 Series). The other was the utilization of the SATA controller is shown in table 1.
