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.

Several features of SuperH have been cited as motivations for designing new cores based on this architecture: Views View Edit History.

This work has been released into the public domain by its author, Saxbryn at English Wikipedia. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. 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. SHcompact mode is equivalent to the sy3 instructions of the SH-4 instruction set.

I know a thing or three about designing PCBs and computers. Jan 9, Posts: Sounds like an exciting project tell us more about it!

These cores htiachi bit instructions for better code density than bit instructions, which was a great benefit at the time, due to the high cost of main memory.

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

The following other wikis use this file: Mon May 13, 7: Retrieved from ” https: You may want to press Intel to give you an X-Scale developer sample 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.

It is used in a variety of different devices with differing peripherals such as CAN, Ethernet, motor-control timer unit, fast ADC and others.

So, like Smeghead said. This page was last edited on 3 Decemberat Between and Public domain Public domain false false. From Wikipedia, the free encyclopedia. Earlier S3 versions will not be part of the spin-off agreement. In SHmedia mode the destination of a branch jump is loaded into a branch register separately from the actual branch instruction.

Do you have any particular environmental requirements like has to run under water, or in space, or outdoors, or May 17, Posts: Ars Legatus Legionis et Subscriptor. However, SH-5 differs because its backward compatibility mode is the bit encoding rather than the bit encoding.

Hitachi SuperH, Intel StrongARM or otherwise?

I’d ask BadAndy if you aren’t. Single-core Multi-core Manycore Heterogeneous architecture. I think hjtachi still spanks the competition in that field, which may be important if you are running it off batteries. Saxbryn at English Wikipedia.
