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.

It provides 16 general purpose registers, a vector-base-register, global-base-register, and a procedure register. The devices feature standard peripherals such as CANEthernetUSB and more as well as more application specific peripherals such as motor control timers, TFT controllers and peripherals dedicated to automotive powertrain applications.

In some countries this may not be legally possible; if so: In SHmedia mode the destination of a branch jump is loaded into a branch register separately from the actual branch instruction. Unfortunately, I can’t help you with your question.

For all we know, a Z80 could be sufficient. Branch prediction Memory dependence prediction. You may want to press Intel to give you an X-Scale developer sample 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.


I presume y’all have some experience in embedded programming? A derivative was also used with the original SH-2 core. What does the product have to do? I’d ask BadAndy if you aren’t. Single-core Multi-core Manycore Heterogeneous architecture.

What problem are you trying to solve? It is implemented by microcontrollers and microprocessors for embedded systems.

Additional instructions are easy to add. The original description page was here.

Lemme know if you need some advice. 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.

Hitachi SuperH, Intel StrongARM or otherwise?

Sun May 12, 1: The linux cross development tools you build if you follow the linuxdevices article are the same vintage gcc that arm uses and 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.

As of [update]many of the original patents for the SuperH architecture are expiring and the SH2 CPU has been reimplemented as open source hardware under the name J2. It would help if you gave more info about your requirements.

Thu May 09, 7: Mon May 13, 7: AMD won’t give a rat’s ass about it So, like Smeghead said. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.


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