It is historically notable as the first CMOS microprocessor. [1] The first production model was the two-chip CDP1801R and CDP1801U , which were later combined into the single-chip CDP1802 . [ 2 ] The 1802 represented the majority of COSMAC production, and today the entire line is known simply as the RCA 1802 .
If the product key used for activation is lost, then product key finders, readily available on the Internet, can decrypt the key from a local installation, however only SLP keys allow the user to avoid activation upon re-installation. [3] In the SLP 2.x implementations, BIOS report the ACPI SLIC table to the operating system.
INT 10h is fairly slow, so many programs bypass this BIOS routine and access the display hardware directly. Setting the video mode, which is done infrequently, can be accomplished by using the BIOS, while drawing graphics on the screen in a game needs to be done quickly, so direct access to video RAM is more appropriate than making a BIOS call ...
Award BIOS setup utility on a standard PC. A modern BIOS setup utility has a text user interface (TUI) or graphical user interface (GUI) accessed by pressing a certain key on the keyboard when the PC starts. Usually, the key is advertised for short time during the early startup, for example "Press DEL to enter Setup". The actual key depends on ...
The HuC6280 8-bit microprocessor is Japanese company Hudson Soft's improved version of the WDC 65C02 CPU, an upgraded CMOS version of the popular NMOS-based MOS Technology 6502 8-bit CPU, manufactured for Hudson by Seiko Epson and NEC. The most notable product using the HuC6280 is NEC's TurboGrafx-16 video game console.
The 65C02 is a low cost, general-purpose 8-bit microprocessor (8-bit registers and data bus) with a 16-bit program counter and address bus.The register set is small, with a single 8-bit accumulator (A), two 8-bit index registers (X and Y), an 8-bit status register (P), and a 16-bit program counter (PC).
The HD64180 is a Z80-based embedded microprocessor developed by Hitachi with an integrated memory management unit (MMU) and on-chip peripherals. [1] It appeared in 1985. [2] The Hitachi HD64180 "Super Z80" was later licensed to Zilog and sold by them as the Z64180 and with some enhancements as the Zilog Z180.
One key difference between the EV3 and later models was the absence of a floating-point unit. [22] The first version, the Alpha 21064 or EV4, is the first CMOS microprocessor whose operating frequency rivalled higher-powered ECL minicomputers and mainframes. The second, 21164 or EV5, is the first microprocessor to place a large secondary cache ...
