The two CCITT-approved interfaces are called basic rate and primary rate, Both interfaces can provide data or voice service simultaneously and circuit-switched or packet-switched connections on the same transmission channel. Basic Rate Interface consists of two 64 kb/s information channels (B channels) used for voice and data, and one 16 kb/s packet-switched data channel (D-channel) used for signaling and data. The Band 0 channels are full duplex bit streams, They are time-division multiplexed into a common stream containing both user information and signaling, The basic rate interface serves small end-systems such as voice/data workstations and terminal adapters for non-ISDN devices, Primary Rate Interface consists of twenty-three 64 kb/s B-channels for voice and data plus one 64 kb/s D-channel for,signaling, This interface is based on the DS1 transmission rate of 1.544 Mb/s. The signaling is performed on the D-channel, allowing the user a full 64 kb/s range tin the B-channels. Typical applications are connecting a PBX or mainframe compl'lter to an ISDN.

The MMU performs address translation by mapping virtual memory addresses to physical memory addresses. It supports both demand paged and demand segmented virtual memory systems, allowing 4 Gbytes of virtual memory and up to 4 Gbytes of physical memory per process. The MMU also allows the use of shared segments for intertask communication. Access privileges for each segment provide system protection. The WE 32101 Memory Management Unit is available in 10-, 14-, and 18-MHz versions; is available in a 125-pin square, hermetic, ceramic pin grid array package and requires a single +5 V supply. The 4 Gbyte virtual address space is subdivided into four sections with as many as 8K segments per section. Segments may be as large as 128 Kbytes of contiguous space, or may be further subdivided into as many as sixty-four 2 Kbyte pages. The segments are mapped by the MMU into the physical address space. For each of the four execution levels, there are four access permissions associated with segments - execute only, read/execute, read/write/execute, no access. The MMU contains descriptor caches, section RAMs, and MMU registers; all are addressable as memory locations. Each virtual memory section has a segment descriptor cache, page descriptor cache, base address register, and section length register associated with it. The four MMU registers are dedicated to decoding and reporting the status of the currently active virtual address.

A 64-entry, fully associative page descriptor cache provides a high hit rate. Transparent multiple contexts are supported for faster context switching. The MMU also allows the use of shared segments for interprocess communication. The on-chip, 4-Kbyte, two-way, set-associative instruction/data cache returns data with zero wait states on WE 32200 CPU virtual and physical memory accesses. Transparent data cache miss-processing and zero wait-state hits significantly reduce overall system access wait states.

Spring 1988 12-7 Microprocessors and Peripherals WE 32103 DRAM Controller Description The WE 32103 DRAM Controller provides address multiplexing, access and cycle time management, and refresh control for DRAM devices. In a single chip, it provides the Interface for high-performance, high reliability, 16- and 32-bit wide, dynamic memory subsystems. Its general-purpose interface is programmable, optimizing system performance for a wide range of memory configurations. The DRAM controller is capable of addressing up to 16 Mbytes of memory. The WE 32103 DRAM Controller is available in a 125-pin, square, hermetic, ceramic pin grid array package; is available in 10-, 14-, and 18-MHz versions; and requires a single +5 V supply. The important features of the WE 32103 DRAM Controller are: Memory Access/Address Translation Overlap To provide an overlap of memory accesses with address translation, the DRAM controller uses a pretranslation technique. This feature can be used in virtual memory systems that use paged segments. In such systems, the lower order bits of the virtual address do not change during translation. The DRAM controller can use these low-order bits to drive the row address and assert the row address strobe while the WE 32101 Memory Management Unit is translating the remaining portion of the address. Multiword Memory Transfers Byte, half-word, 3-byte, 4-byte, 2-word, 3-word, and 4-word read and write operations are supported. For I/O bound user applications, use of multiword bus transactions can double the rate of block data transfer over the system data bus. Multiword access reduces the overhead latencies associated with bus arbitration, successive address transmission, and subsequent address translation. The DRAM controller provides 2-word reads to the WE 32100 CPU, as well as 4-word reads and writes to the WE 32104 DMA Controller. The DRAM controller provides multiword access by receiving an access size request, supplying a handshake, and manipulating DRAM strobes for page, nibble, or cycling RAS. Error Detection and Correction All of the signals needed to interface with an error detection and correction unit are provided. The DRAM controller turns partial-word write operations and read operations with correctable errors into a user-transparent read-modify-write memory cycle. For high reliability applications, programmable support is provided for periodic error scrubbing and automatic check-bit Initialization. 12-8 Spring 1988 (Refer to Section 19 for typical applications of this product_) Microprocessors and Peripherals WE 32103 DRAM Controller Dual-Port Configuration A dual-ported memory can be controlled uSing two DRAM controllers. One IS configured as a master, while the other is configured as a slave. Along with its normal tasks, the master performs memory arbitration and refreshes. The slave normally 3-states its memory outputs until It is granted ownership of the shared memory outputs by the master DRAM controller. Refresh Configurations The DRAM controller can be programmed to provide a wide variety of refresh schemes. It has both a programmable, internal refresh timer and an external refresh request input. The refresh mode can be programmed for distributed refresh. Combinations of internal, external, and distributed refresh modes allow many different applications. An explicit refresh interval timer is accessible to the programmer. Configuration Registers Configuration registers are provided to optimize the controller for a wide range of DRAM configurations.

Microprocessors and Peripherals WE 321SG C-Software Generation Programs (CPLU Release 4.2) Description The WE 321SG C-Software Generation Programs facilitate using a host UNIX System V for creating software for the WE 32100 Microprocessor. This support software provides utility programs that enable the user to write applications software in C language or assembly language. The C-Software Generation Programs are binary products that satisfy a native programming environment. The WE 321SG C-Software Generation Programs replace any other Native C compiler already installed in an AT&T 3B2 Computer System running UNIX System V Release 2.0.5/2.1/3.0/3.1/3.1.1 or UNIX System VIVME Release 2.1/3.1. An additional software package that is available with the C-Software Generation Programs, Advanced Programming Utilities EnVironment (APU), contains commands such as ctrace, lex, and yacc. These and other commands provide the user with a set of programming tools that allow the programmer to do advanced programming and debugging, create shared libraries, and work in an environment where it may be necessary to track and maintain versions of files and programs. The software generation programs can generate code in either of two floatingpoint modes, MAU or FPE. The MAU mode provides enhanced floating-point performance through the use of in-line code generation for the WE 32106 Math Acceleration Unit (MAU). Alternatively, at the cost of lower performance, the FPE mode supports target systems operating both with and without a math acceleration unit. The FPE mode compiles floating-point operations as calls to library routines that either execute MIS or emulate the operations, depending on whether a math acceleration unit has been determined to be present at process start-up. The software generation programs also provide high-performance math libraries, integer and floating-point optimizations, and floating-point support that conforms to the IEEE Standard for Binary Floating-Point ArithmetiC (ANSI/IEEE Std. 754-1985). The C-Software Generation Programs comply completely with the UNIX System V Interface Definition (SVID) (i.e., passes the UNIX System V Verification Suite). Features for the WE 321SG Software Generation Programs Utilities • C compiler • Object file compressor • Assembler • Object and archive file converter • Link editor • Object file dumper • Disassembler • Source code lister • Object code optimizer • Object file orderer • Archiver and library maintainer • Symbol table printer • Object file host converter • Object file stripper (Refer to Section 19 for typical applications of this product.)

It can function as either a stand-alone or as a distributed processor linked by a network to other workstations. A workstation is generally designed with one or more 32-bit microprocessor sets, auxiliary storage, very high resolution CRT, 70-167 MB Winchester disk, and virtual memory management. The graphics capabilities of a technical workstation are sophisticated in terms of complexity, precision, and computational speed, and separate graphics processors are often used with floating-point units.
