SD 4.1 Hardware Validation Platform

Overview

The rapid proliferation of high-performance mobile and handheld devices has resulted in increasing requirements for non-volatile memory. Memory interfaces with larger capacities and faster access times are needed.

The SD memory card interface dominates the mobile storage markets such as tablets, smartphones, video camcorders, and many other portable or stationary consumer electronics. Designed to be cost-effective and Linux based, this SD 4.1 hardware validation platform (HVP) consists of Arasan’s SD4.0 IP mapped into FPGA’s, offering full speed physical connectivity to a complementary SoC host or memory card device. Owing to its active participation in the SDA standards body, and being the first to market SD controller IP, Arasan’s SD controller IP implementation is considered a reference implementation in the industry.

An equally important part of the SD 4.1 HVP is the software stack, which abstracts all the low-level software drivers and hardware to a loadable shared object with easy to use API’s. Hence, an applications software, validation or systems engineer does not need to delve into the protocol and signaling details and considers the Arasan platform as a programmable complementary device. The SD 4.1 HVP can be used by system developers, system integrators, software developers and system quality analysts to debug as well as validate their products during the product life-cycle.
