In the UK, Ferranti, with their bipolar collector diffused isolation (CDI) arrays, pioneered the commercial use of gate arrays and for many years this was by far the most widely used technology.
The Series 37 CPU chip is a CMOS gate array using nearly 8000 gates.
To reduce the IC count on the video card, a PLA (programmable logic array) and a TTL gate array are used. The gate array implements most of the circuitry of the graphics controller section, including control of the RAM. Compared to discrete circuitry, the gate array consumes one fifth the space, one fourth the power, and one half the cost.
The PA 8000s will initially run at 180 MHz, with the rest of the system running at 120 MHz. Except for the PA 8000 and associated SRAMs and DRAMs, the bulk of the system logic is implemented in Fujitsu CG61 0.35-μm gate arrays, as shown in Table I. (Processor Interface, Crossbar, Memory Interface, Node-to-Node Interface) One additional gate array is implemented in the much less expensive CG51 0.5-μm process. (I/O Interface)
All modules utilize LSI Logic LCA100K series gate arrays for the system bus interface and for on-board logic functions. The LSI Logic LCA100K features up to 235K two-input NAND gates. All modules use the same custom I/O driver circuit within their respective gate arrays to drive and receive the system bus. A custom 419-pin pin grid array (PGA) package was developed to house all bus interface gate arrays. ... A minimal DEC 7000 system includes 430,000 gates of logic contained in gate arrays, whereas a minimal VAX 6000 Model 200 includes 94,000 gates.
