Freescale S08
The 9S08 (68HCS08 or S08 for short) is a 8-bit microcontroller (µC) family originally produced by Motorola, later by Freescale Semiconductor, and currently by NXP, descended from the Motorola 6800 microprocessor. It is a CISC microcontroller. A slightly extended variant of the 68HC08, it shares upward compatibility with the aging 68HC05 microcontrollers, and is found in almost any type of embedded systems. The larger members offer up to 128 KiB of flash, and 8 KiB of RAM via a simple MMU which allows bank-switching 16 KiB of the address space and an address/data register pair which allows data fetches from any address. The paging scheme used allows for a theoretical maximum of 4MB of flash. MMU equipped variants offer two extra CPU instructions, CALL and RTC, which are used instead of JSR and RTS respectively when dealing with subroutines placed in paged memory, allowing direct page-to-page subroutine calls. In a single atomic operation, CALL saves and RTC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Rabbit 2000
The Rabbit 2000 is a high-performance 8-bit microcontroller designed by Rabbit Semiconductor for embedded system applications. Rabbit Semiconductor has been bought by Digi International, which is since selling the Rabbit microcontrollers and hardware based on them. The instruction set is based on the original Z80 microprocessor, but with some additions of new instructions as well as deletions of some instructions. Among the Z80 instructions missing in the Rabbit, cpir is particularly notable, since it allows for much more efficient implementations of some often-used standard C functions such as strlen(), strnlen() and memchr(). According to the Rabbit documentation, it executes its instructions 5 times faster than the original Z80 microprocessor, that is, similarly to the Zilog eZ80. The Rabbit 3000 is a variant of the Rabbit 2000 with the same core, but more powerful integrated peripherals. The Rabbit 3000A variant adds a small number of additional instructions for I/O and large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EZ80
The Zilog eZ80 is an 8-bit microprocessor from Zilog, introduced in 2001. eZ80 is an updated version of the company's first product, the Z80 microprocessor. Design The eZ80 (like the Z380) is binary compatible with the Z80 and Z180, but almost three times as fast as the original Z80 chip at the same clock frequency. The eZ80 has a three-stage pipeline. Available at up to 50 MHz (2004), the performance is comparable to a Z80 clocked at 150 MHz if fast memory is used (i.e. no wait states for opcode fetches, for data, or for I/O) or even higher in some applications (a 16-bit addition is 11 times as fast as in the original). The eZ80 also supports direct continuous addressing of 16 MB of memory without a memory management unit, by extending most registers (HL, BC, DE, IX, IY, SP, and PC) from 16 to 24 bits. In order to do so, the CPU has a full 24-bit address mode called ADL mode. Z80 register pairs are extended to 24 bits and renamed with U e.g. HL is now HLU et ...

Z180
The Zilog Z180 eight-bit processor is a successor of the Z80 CPU. It is compatible with the large base of software written for the Z80. The Z180 family adds higher performance and integrated peripheral functions like clock generator, 16-bit counters/timers, interrupt controller, wait-state generators, serial ports and a DMA controller. It uses separate read and write strobes, sharing similar timings with the Z80 and Intel processors. The on-chip memory management unit (MMU) has the capability of addressing up to 1 MB of memory. It is possible to configure the Z180 to operate as the Hitachi HD64180. Variants Z80182 The Zilog Z80182, introduced in 1997, is an enhanced, faster version of the older Z80 and is part of the Z180 microprocessor family. It's nicknamed the ''Zilog Intelligent Peripheral Controller'' (ZIP). It's also fully static (the clock can be halted and no data in the registers will be lost) and has a low EMI option that reduces the slew rate In electronics, sl ...

Zilog
Zilog, Inc. is an American manufacturer of microprocessors and 8-bit and 16-bit microcontrollers. It is also a supplier of application-specific embedded system-on-chip (SoC) products. Its most famous product is the Z80 series of 8-bit microprocessors that were compatible with the Intel 8080 but significantly cheaper. The Z80 was widely used during the 1980s in many popular home computers such as the TRS-80, MSX, Amstrad CPC and the ZX Spectrum, as well as arcade games such as '' Pac-Man''. The company also made 16- and 32-bit processors, but these did not see widespread use. From the 1990s, the company focused primarily on the microcontroller market. The name (pronunciation varies) is an acronym of ''Z integrated logic'', also thought of as "Z for the last word of Integrated Logic". In the oral history interview video which Federico Faggin (co-founder of Zilog) recorded for the Computer History Museum, he pronounced Zilog with a long "i" () consistently. History Zilog was ...

STM8
The STM8 is an 8-bit microcontroller family by STMicroelectronics. The STM8 microcontrollers use an extended variant of the ST7 microcontroller architecture. STM8 microcontrollers are particularly low cost for a full-featured 8-bit microcontroller. Architecture The STM8 is very similar to the earlier ST7, but is better suited as a target for C due to its 16-bit index registers and stack pointer-relative addressing mode. Although internally a Harvard architecture it has "memory bridge" that creates a unified 24-bit address space, allowing code to execute out of RAM (useful for in-system programming of the flash ROM), and data (such as lookup tables) to be accessed out of ROM. On access the "memory bridge" stalls the CPU if required so that RAM-like write access to the flash ROM is possible. Code execution from the EEPROM is denied and creates a reset event. Random access to data above 64K is limited to special "load far" instructions; most operations' memory operands can access ...

Motorola 68HC08
The 68HC08 (HC08 in short) is a broad family of 8-bit microcontrollers originally from Motorola Semiconductor, later from Freescale Semiconductor. HC08's are fully code-compatible with their predecessors, the Motorola 68HC05. Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as well as memory-mapped I/O. This family has five CPU registers that are not part of the memory. One 8-bit accumulator A, a 16-bit index register H:X, a 16-bit stack pointer SP, a 16-bit program counter PC, and an 8-bit condition code register CCR. Some instructions refer to the different bytes in the H:X index register independently. Among the HC08's there are dozens of processor families, each targeted to different embedded applications. Features and capabilities vary widely, from 8 to 64-pin processors, from LIN connectivity to USB 1.1.
