Adaptec also developed generic SCSI disk and CD-ROM drivers for DOS (ASPICD.SYS and ASPIDISK.SYS). [3]: 60–61 At least a couple of other programming interfaces for SCSI device drivers competed with ASPI in the early 1990s, including CAM (Common Access Method), developed by Apple; and Layered Device Driver Architecture, developed by Microsoft.
Adaptec, Inc., was a computer storage company and remains a brand for computer storage products. The company was an independent firm from 1981 to 2010, at which point it was acquired by PMC-Sierra , which itself was later acquired by Microsemi , which itself was later acquired by Microchip Technology .
Adaptec ACB-4000A SASI card from 1985. SCSI is derived from the Shugart Associates System Interface (SASI), [4] developed beginning 1979 [5] and publicly disclosed in 1981. [1] Larry Boucher is considered to be the "father" of SASI and ultimately SCSI due to his pioneering work first at Shugart Associates and then at Adaptec, which he founded ...
LTspice schematics are stored as an ASCII text file with a filename extension of "asc". [ 30 ] The following example shows the contents from a small LTspice schematic file for a simple RC circuit with four schematic symbols : V1 is 10 volt DC voltage source, R1 is 1K ohm resistor , C1 is 1 uF capacitor , ground .
Additionally, open-source hardware organizations such as OpenCores are collecting free IP cores, paralleling the open-source software movement in hardware design. Soft macros are often process-independent (i.e. they can be fabricated on a wide range of manufacturing processes and different manufacturers).
The Advanced Scientific Computer (ASC) is a supercomputer designed and manufactured by Texas Instruments (TI) between 1966 and 1973. [1] The ASC's central processing unit (CPU) supported vector processing , a performance-enhancing technique which was key to its high-performance.
The number of bits per character -- currently almost always 8-bit characters, but historically some transmitters have used a five-bit character code, six-bit character code, or a 7-bit ASCII. Endianness: the order in which the bits are sent; The speed or bits per second of the line (equal to the Baud rate when
Sun has published a number of Sun BluePrints to assist application programmers in developing and deploying software on T1 or T2-based CoolThreads servers. The main article, Tuning Applications on UltraSPARC T1 Chip Multithreading Systems , [ 5 ] addresses issues for general application programmers.
