1.1 Introduction

The Hitachi SuperH

microprocessor-based Hardware Architecture Reference Platform

(HARP) consists of a printed circuit board (PCB) or board set, schematics, sample software

device driver source code, CPLD code, gerber files, bill of materials, and documentation. The

schematics, sample software device driver source code, OEM abstraction layer (OAL) code,

CPLD code, and gerber files are available to customers who complete a release form inside

the original shipping box or available from a Hitachi sales representative.

The HARP serves as a complete, tested development platform and functional design that

customers may incorporate all or part there of into their own end product. Generally, the

HARP system ships as a two-board set: a base board with SH3 (SH770X), SH3-DSP

(SH772X) microprocessor, SDRAM, flash memory, serial port, Ethernet connection, and

expansion bus connector. JTAG emulator connector, CompactPCI interface. A daughter board

(Tahoe) offers more functional capability. The HARP offers flexibility through board-to-board

connectors allowing future HARPs to ship as one base board or a base board plus multiple

daughter boards.

Several operating systems with sample device driver software or operating system board

support packages run on the HARP. Operating systems running on or planning to run on the

HARP include Microsoft’s Windows CE, Wind River Systems’ VxWorks and Tornado,

OSSL’s QNX, Linux, and Accelerated Technologies’ Nucleus+. Check with Hitachi for a

current list of suppliers and specific HARP system.

Hitachi offers the HARP as a stand-alone development board (SDB). A third party offers a

chassis with CompactPCI backplane and built-in power supply. The chassis is known as the

HARP case.

Optional development tools can be purchased from Hitachi and third-party suppliers. These

tools include Hitachi’s E10A emulator, Hitachi’s Debugging Interface (HDI), and Agilent’s

logic analyzer.
