Motherboard of the NeXTcube from 1990 having a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface. In most designs the 56000 is dedicated to one single task, because digital signal processing using special hardware is mostly real-time and does not allow any interruption .
An update of RSS is CPS, a Windows-based version of the package used for some of Motorola's newer radio models. Radios are connected to PCs via the serial port, [2] and proprietary programming cables. The use of genuine Motorola OEM programming cables is strongly suggested, as aftermarket brands are not as reliable and could lead to radio damage.
OpenEZX was a project active from 2004 to 2008, which gathered information about the Linux based Motorola EZX phone platform. [1] [2] [3]It tried to provide a 100% free software stack for those phones, especially a way to avoid any proprietary filesystem and/or device drivers.
As originally used, firmware contrasted with hardware (the CPU itself) and software (normal instructions executing on a CPU). It was not composed of CPU machine instructions, but of lower-level microcode involved in the implementation of machine instructions. It existed on the boundary between hardware and software; thus the name firmware.
The PowerPC 604 contains 3.6 million transistors and was fabricated by IBM and Motorola with a 0.5 μm CMOS process with four levels of interconnect. The die measured 12.4 mm by 15.8 mm (196 mm 2) and drew 14-17 W at 133 MHz. It operated at speeds between 100 and 180 MHz. [22] [23] [24] Power PC 604 RISC microprocessor, lecture by Marvin Denman
Other than ASCII-to-hex converted comments in S0 header records, the SREC file format doesn't officially support human-readable ASCII comments, though some software ignores all lines that don't start with "S" and/or ignores all text after the Checksum field (thus trailing text is sometimes used (incompatibly) for comments).
Proprietary firmware poses a significant security risk to the user because of the direct memory access (DMA) architecture of modern computers and the potential for DMA attacks. [citation needed] Theo de Raadt of OpenBSD suggests that wireless firmware are kept proprietary because of poor design quality and firmware defects.
68HC11 block diagram. Internally, the HC11 instruction set is backward compatible with the 6800 and features the addition of a Y index register. [a] It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter.
