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.

If that were the case, it would be a helluva lot easier to design a system around one.

AMD won’t give a rat’s ass about it Additional instructions are easy to add.

Hitachi SuperH, Intel StrongARM or otherwise?

Superscalar 2-way instruction execution and a vector floating point unit particularly suited to 3d graphics were the highlights of this architecture. 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. It 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.

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. The SH-5 design supported two modes of operation.

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

You may want to press Intel to give you an X-Scale developer sample SuperH’s initial product will be the SH4 core. 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.

Reduced instruction set computer RISC architectures. AMD Alchemy in that order. The last of the SH-2 patents expired in
