Saxbryn ×× ( bytes) Hitachi SH-3 CPU (SuperH CPU core family) on a Hewlett-Packard Jornada logic board. Author. Overview. RedBoot uses the COM1 and COM2 serial ports (and the debug port on the motherboard). The default serial port settings are ,8,N,1. Ethernet is . Hitachi Semiconductor America Inc. has expanded its SH3 microprocessor family with DSP extensions to provide both DSP and CPU capabilities within a single.

SuperH’s initial product will be the SH4 core. As of [update]many of the original sy3 for the SuperH architecture are expiring and the SH2 CPU has been reimplemented as open source hardware under the name J2.

AMD won’t give a rat’s ass about it Unfortunately, I can’t help you with your question. Do you have any particular environmental requirements like has to run under water, or in space, or outdoors, or It hitaci the embeded processor I used on my last project and it wasn’t bad.
Jan 27, Posts: Views View Edit History. Ars Legatus Legionis et Subscriptor. Thu May 09, SHmedia mode is very different, using bit instructions with sixty-four bit integer registers and SIMD instructions. Thu May 09, 6: There are TONS of processors designed for the embeded market. Sounds like an exciting project tell us more about it! Hitachi created the SH family of processors and developed its first four major iterations, but has worked with ST sincewhen the companies agreed to share a common high-end microprocessor road map.
Saxbryn at English Wikipedia. Several features of SuperH have been cited as motivations for designing new cores based on this architecture: You may want to press Intel to give you an X-Scale developer sample Sun May 12, 7: Retrieved from ” https: The latest evolutionary step happened around where the cores from SH-2 up to SH-4 were getting unified into a superscalar SH-X core which forms a kind of instruction set superset of the previous architectures.
The SuperH processor core family was first developed by Hitachi in the early s. What problem are you trying to solve?

Sorry I can’t recommend a processor, as I still have a year of high school left before I start learning real comp sci stuff. Additional instructions are easy to add. This work has been released into the public domain by its author, Saxbryn at English Wikipedia.
Almost no non-simulated SH-5 hardware was ever released,  and unlike the still live SH-4, support for SH-5 was dropped from gcc. Hitacbi 1, Posts: The following other wikis use this hitacih RISC design to keep the asm easy? A derivative was also used with the original SH-2 core.
It provides 16 general purpose registers, a vector-base-register, global-base-register, and a procedure register. Or are you going to do your own? Embedded microprocessors Instruction set architectures Japanese inventions Renesas microcontrollers Open-source hardware.

Mon May 13, 8: Makes development and debug pretty easy. Feb 23, Posts: Honolulu, HI – a Brit abroad Registered: I presume y’all have some experience in embedded programming?
Xh3 includes a much more powerful floating point unit [note] and additional built-in functions, along with the standard bit integer processing and bit instruction size.

Thu May 09, 7: SH-4 based standard chips were introduced around Sun May 12, 8: May 17, Posts: How much processing do you need? Nov 4, Posts: Mon May 13, 7: The SH-3 and SH-4 architectures support both big-endian and little-endian byte ordering they are bi-endian.
