      The impact of the VAX on the world had a lot to do with the fact that it was bulletproof. It was robust. It really worked as advertised. That was Dave’s work.” While Cutler’s operating systems work on the PDP 11 and VAX are legendary, Bell is quick to add that the dynamic range of Cutler’s work at DEC is often overlooked. in producing the audio,I/O devices availabi'e today.

    Device drivers literally drive everything you're interested in--disks, monitors, keyboards, modems--everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge.9/10().

    The main body of the book assumes you have had a full course in logic design. I do NOT make that strong an assumption. I just assume you had We will start with appendix B, which is a logic design review. However since is a prerequisite, we will go rather quickly over some parts. Many of the figures in these notes are based on figures. Performance is potentially limited in a tightly coupled system by a number of factors. These include various system components such as the memory bandwidth, CPU-to-CPU communication bandwidth, the memory available on the system, the I/O bandwidth, and the common bus bandwidth. Parallel processing advantages of shared memory systems are these.

The I/O subsystem had two independent bit buses that communicated with the I/O and graphics options available.

One of the buses interfaced to a TURBOchannel slot, the firmware contained within ROMs and the graphics options. The other bus interfaced to the Ethernet and EDAL controllers. EDAL was a bit general-purpose bus for I/O. Ideal for Oracle database programmers and administrators using the UNIX platform.

On VAX and Alpha systems, GK is the device mnemonic for the generic SCSI class driver (GKDRIVER); p represents the SCSI port ID (for instance, the controller ID A or B); d represents the SCSI device ID (a digit from 0 to 7); 0 signifies the digit zero; and u represents the SCSI logical unit number (a digit from 0 to 7).

I recently acquired an O'Reilly book on UUCP to refresh my memory on setting up and running UUCP Systems. It has an interesting comment in the appendix on "UUCP for Non-UNIX Platforms". UUCP for VMS DECUS UUCP is an implementation of UUCP for the DEC Vax system.

Some underlying I/O subsystems implement hardware-level caching of disk reads and writes to speed up their response times to I/O requests.

It is important to ensure that such subsystems are configured to acknowledge write requests only after the written data is guaranteed to be safe.

Free memory in VAX or VMS environments is actually memory. The Massbus is a high-performance computer input/output bus designed in the s by Digital Equipment Corporation (DEC).

These are ports that may be configured by software, on a pin-by-pin basis, as either a digital input or digital output. As digital inputs, they may be used to read the state of switches or push buttons, or. Comprehensive and convenient, the book focuses on the kernel of the VAX/VMS Version operating system: process management; memory management; the I/O subsystem; the mechanisms that transfer control to, from, and among these; and the system services that support and complement them.

The processor (or central processing unit, CPU) is the heart of the computer. Shown in Fig. 3, a simple processor contains control circuits for fetching and executing instructions, an arithmetic logic unit (ALU) for manipulating data, and registers for storing processor status and a small amount of data.

To refine protection even further requires putting protection capabilities into the hands of individual programmers, so that protection policies can be implemented on the application level, i.e. to protect resources in ways that are known to the specific applications but not to the more general operating system.
