ARM7
ARM7 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. The ARM7 core family consists of ARM700, ARM710, ARM7DI, ARM710a, ARM720T, ARM740T, ARM710T, ARM7TDMI, ARM7TDMI-S, ARM7EJ-S. The ARM7TDMI and ARM7TDMI-S were the most popular cores of the family. ARM7 cores were released from 1993 to 2001 and no longer recommended for new IC designs; newer alternatives are ARM Cortex-M cores. Overview This generation introduced the Thumb 16-bit instruction set providing improved code density compared to previous designs. The most widely used ARM7 designs implement the ARMv4T architecture, but some implement ARMv3 or ARMv5TEJ. ARM7TDMI has 37 registers (31 GPR and 6 SPR). All these designs use a Von Neumann architecture, thus the few versions containing a cache do not separate data and instruction caches. Some ARM7 cores are obsolete. One historically significant model, the ARM7DI"ARM7DI Data Sheet"; Document Number ARM DDI 0027D; Issued: ...

ARM Architecture
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer, RISC instruction set architectures (ISAs) for central processing unit, computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses semiconductor intellectual property core, cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktop computer, desktops and server (computing), servers, including Fugaku (supercomputer), Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used ...

Risc PC
Risc PC was a range of personal computers launched in 1994 by Acorn, replacing the Archimedes series. The machines use the Acorn developed ARM CPU and were thereby not IBM PC-compatible. At launch, the original Risc PC 600 model was fitted as standard with an ARM 610, a 32-bit RISC CPU with 4 KB of cache and clocked at 30 MHz. CPU technology advanced rapidly in this period though and within only two years a DEC StrongARM could be installed at 233 MHz which was around 8 times faster. The machines were supplied with the RISC OS operating system which has a windowed cooperative multi-tasking design. Unusually for a PC of the period the O/S was stored in ROM, which enabled a relatively fast boot time. In addition Acorn sold a Virtual PC package that permitted x86 applications to be run in a virtual machine, they also supported the development of an ARM Linux distribution, from 1996. In contrast to most contemporary IBM clones, the machines supported multiple p ...

AT91SAM7
Atmel ARM-based processors are microcontrollers and microprocessors integrated circuits, by Microchip Technology (previously Atmel), that are based on various 32-bit ARM processor cores, with in-house designed peripherals and tool support. Overview ARM licenses the core design for a series of 32-bit processors. ARM does not manufacture any complete silicon products, just intellectual property (IP). The ARM processors are RISC (reduced instruction set computing). This is similar to Microchip's AVR 8-bit products, a later adoption of RISC architecture. Whereas the AVR architecture used Harvard architecture exclusively, some ARM cores are Harvard (Cortex-M3) and others are Von Neumann architecture (ARM7TDMI). Semiconductor companies such as Microchip take the ARM cores, which use a consistent set of instructions and register naming, and add peripheral circuits such as ADCs (analog to digital converters), clock management, and serial communications such as USART, SPI, I2C, CAN, LIN, ...

System On A Chip
A system on a chip (SoC) is an integrated circuit that combines most or all key components of a computer or Electronics, electronic system onto a single microchip. Typically, an SoC includes a central processing unit (CPU) with computer memory, memory, input/output, and computer data storage#Secondary storage, data storage control functions, along with optional features like a graphics processing unit (GPU), Wi-Fi connectivity, and radio frequency processing. This high level of integration minimizes the need for separate, discrete components, thereby enhancing Performance per watt, power efficiency and simplifying device design. High-performance SoCs are often paired with dedicated memory, such as LPDDR, and flash storage chips, such as Universal Flash Storage, eUFS or eMMC, which may be stacked directly on top of the SoC in a Package on a package, package-on-package (PoP) configuration or placed nearby on the motherboard. Some SoCs also operate alongside specialized chips, such ...

Million Instructions Per Second
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches and no cache contention, whereas realistic workloads typically lead to significantly lower IPS values. Memory hierarchy also greatly affects processor performance, an issue barely considered in IPS calculations. Because of these problems, synthetic benchmarks such as Dhrystone are now generally used to estimate computer performance in commonly used applications, and raw IPS has fallen into disuse. The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second (kIPS), mega instructio ...

JTAG
JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. It specifies the use of a dedicated debug port implementing a serial communications interface for low-overhead access without requiring direct external access to the system address and data buses. The interface connects to an on-chip Test Access Port (TAP) that implements a stateful protocol to access a set of test registers that present chip logic levels and device capabilities of various parts. The Joint Test Action Group formed in 1985 to develop a method of verifying designs and testing printed circuit boards after manufacture. In 1990 the Institute of Electrical and Electronics Engineers codified the results of the effort in IEEE Standard 1149.1-1990, entitled ''Stand ...

Nokia 6110
The Nokia 6110 is a GSM mobile phone from Nokia announced on 18 December 1997 and released in 1998. It was a hugely popular follower of the Nokia 2110 (1994), and the first of the many Nokia 6xxx series business-targeted phones. Main improvements over the 2110 were reduced size and improved talk time. It was built on the new third generation, Nokia DCT3 hardware platform, and was the first GSM phone to use an ARM processor and the first running on Nokia's Series 20 user interface. The phone shared the same platform as the Nokia 5110 targeted at the consumer market; unlike the 5110, however, it had the advanced user interface with menu icons (it was the first phone with this new interface that would become the future standard), and featured an infra-red port (once again being Nokia's first phone with it). It was also the first phone from Nokia to have the popular ''Snake'' game pre-installed. It was succeeded/complemented by the similar but enhanced 6150. Variants Nokia 619 ...
