	Gate array - Wikipedia, the free encyclopedia
		A Gate array or Uncommitted Logic Array (ULA) is an approach to the design and manufacture of application-specific integrated circuits (ASICS).
		A gate array circuit is a prefabricated circuit with no particular function in which transistors, standard logic gates, and other active devices are placed at regular predefined positions and manufactured on a wafer, usually called master slice.
		The gate array approach reduces the mask costs since fewer custom masks need to be produced.

	Patent 6128770
		Further, all of the input/output logic blocks are characterized by tristatable output buffers to pads and to the internal interconnect which are controlled in response to the program data and/or a control signal generated in the configurable logic array.
		Combinational logic is coupled to the configuration memory and the input multiplexing tree, for generating a plurality of L logic signals in response to the K signals and the program data.
		Control logic 208 is responsive to the mode inputs to the device on line 209 to control the detect logic 204 across line 210 and the frame pointer during loading of the configuration memory 200.

		ULAs had complexities of up to a few thousand gates.
		In the late 1980s, the availability of silicon compilers (such as Design Compiler) that could accept hardware description language descriptions using Verilog and VHDL and compile the logic into to a gate level netlist brought "standard-cell" design into the fore-front.
		A standard-cell library consists of pre-characterized collections of gates (such as 2 input nor, 2 input nand, invertors, etc.) that the silicon compiler uses to translate the original source into a gate level netlist.

	Sinclair ZX81 - Wikipedia, the free encyclopedia
		The I register would be loaded to point to the base of the character set bitmap table in ROM and the R (refresh) counter could be used to count which line in the 8x8-bit bitmap for a character was to be displayed.
		The high bits would be coming from the otherwise-unused interrupt vector register (which is pointing to the character set in ROM), the low three bits would indicate which row of the individual character was currently being scanned.
		In this manner, a byte of display pixels would be forced onto the bus where it could then be fed into a shift register driven by the same crystal used to generate the CPU clock and from there be sent to the TV set.

	Application-specific integrated circuit - Wikipedia, the free encyclopedia
		A logic synthesis tool, such as Design Compiler, transforms the RTL design into a large collection of lower-level constructs called standard cells.
		One definition states that "In a "structured ASIC" design, the logic mask-layers of a device are predefined by the ASIC vendor (or in some cases by a third party).
		For example, in a cell-based or gate array design the user often must design power, clock, and test structures themselves; these are predefined in most Structured/Platform ASICs and therefore can save time and expense for the designer compared to gate-array.

		Gate array is an approach to fast design and manufacture of integrated circuits.
		The gate array approach avoids having to assemble the required logic from large numbers of discrete components which might otherwise be the only other cost effective solution for small runs and prototypes
		Due to mass production of the gate array cirucit's, it is also considerably cheaper than having a purpose-designed chip fabricated.

		The ULA controlled memory access and was able to provide 32K × 8 bits of addressable RAM using 4 × 64K × 1-bit RAM chips (4164).
		The Electron was developed during 1983 as a cheap sibling for the BBC Micro with the intention of capturing the low cost Christmas sales market for that year.
		Although Acorn were able to shrink substantially the same functionality as the BBC into just one custom designed ULA, manufacturing problems meant that very few machines were available for the Christmas period with some shops reporting eight presales for every delivered machine.

	Application-specific integrated circuit
		The first ASIC was probably the ULA (Uncommitted Logic Array) produced by British firm Ferranti[?] around 1980.
		Later versions were generalised into gate arrays with different base dies customised by both metal and polysilicon layers.
		For smaller designs and/or lower production volumes, ASICs are becoming a less attractive solution, as field-programmable gate arrays (FPGAs) grow larger, faster and more capable.

	Ancient Skepticism
		While this is a logical corollary of the suggestion that the skeptic has not made up his mind about the issues of philosophy, anyone familiar with Sextus might question whether he is open to this possibility.
		Within this broader context, ancient philosophical inquiry is characterized both by a remarkable array of conflicting philosophical perspectives and by famous philosophers who were known for dazzling arguments for paradoxical conclusions (that motion is impossible, that nothing exists, that time is an illusion, etc.).
		Given the practical goals of Pyrrhonism, one might argue that the psychological force of Pyrrhonian arguments was as important as their logical force, for it was designed to constrain a Pyrrhonean's attachment to appearances.

	Designing Asics Chapter 0 Introduction: From Discrete Logics to Asics
		In the optimised array, the basic circuit elements are stages, p- n transistor pairs, which are placed in rows and columns.
		Unused stages are removed in the compilation of an optimised array, giving a single integrated circuit which occupies less space, consumes less power, is faster and more reliable than the set of discrete logic elements it replaces in a system.
		Semi-custom Asics, such as gate arrays, consist of arrays of identical circuit elements which are dedicated to specific tasks by the configuration of the layer(s) of metal interconnect.

		It was translated to the individual chips instead of wafer, and instead of attempting individual circuits the idea became that of putting a range of logic functions onto a single chip.
		The gate array chip consists of a circuit that is partially manufactured.
		A natural extrapolation of the small microcomputer manufacturer being able to make use of gate array circuits to economically produce exactly what is required is that the user (or more specifically the local distributor/dealer/ systems house) will also be able to do it.

		In a "structured ASIC" design, the logic mask-layers of a device are predefined and are usually supplied by a third party.
		Design differentiation and customization is achieved by creating custom metal layers that create custom connections between predifined lower-layer logic elements.
		Because only a small number of chip layers must be custom-produced, "structured ASIC" designs have much smaller non-recurring expenditures (NRE) than "standard-cell" or "full-custom" chips, which require that a full mask set be produced for every design.

		The kit was launched at a computer fair in the first week of February 1980, and while it was not a massive success by comparison with the ZX Spectrum, it turned Sinclair's fortunes around, eventually earning him a knighthood, and it sold well enough to persuade him to make a new computer - the ZX81.
		Work on the hardware had begun in September 1979, even before the launch of the ZX80, but it was the development of the uncommitted logic array, or ULA, which allowed the machine to go into production.
		The ULA, produced by Ferranti for Sinclair, reduced the chip count and brought the retail cost of the machine, in kit-form, down to £49.95.
