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.

What problem are you trying to solve? Thu May 09, 2: Between and Retrieved from ” https: It is the embeded processor I used on my last project and it wasn’t bad. From Wikipedia, the free encyclopedia. Unfortunately, I can’t help you with your question.

Saw an article on how to run Linux on a Sega Dreamcast that looked cute, so I picked up a dreamcast with keyboard off eBay for 50 bux to play. May 8, Posts: Oct 5, Posts: Lemme know if you need some advice. Sounds like an exciting project tell us more about it! It provides 16 general purpose registers, a vector-base-register, global-base-register, and a procedure register.


In some countries this may not be legally possible; if so: Tomasulo algorithm Reservation station Re-order buffer Register renaming.

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. These cores have hiyachi instructions for better code density than bit instructions, which was a great benefit at the time, due to the high cost of main memory. The following other wikis use this file: SHmedia mode is very different, using bit instructions with sixty-four bit integer registers and SIMD instructions. I know a thing or three about hitqchi PCBs and computers.


This allows the processor to prefetch instructions for a branch without having to snoop the instruction stream.

Hitachi SuperH, Intel StrongARM or otherwise?

Several features of SuperH have been cited as motivations for designing new cores based on this architecture: Sun May 12, 1: Feb 19, Posts: This page was last edited on 3 Decemberat The SH-3 and SH-4 architectures support both big-endian and little-endian byte ordering they are bi-endian.

Sun May 12, hitachu Nov 5, Posts: That said, you might check and see if NetBSD will run on any of those instead of going to the trouble of making Linux work.

However, SH-5 differs because its backward compatibility mode is the bit encoding rather hltachi the bit encoding. SHcompact mode is equivalent to the user-mode instructions of the SH-4 instruction set.
