The computer within the Patriot system is a 24-bit parallel militarized computer with fixed and floating point capability. The WCC is organized in a multiprocessor configuration which operates at a maximum clock rate of 6 megahertz.
Weapons control computer.
The WCC provides the necessary data processing for the Patriot FU, including capability for communications with other FUs or battalions through a routing logic radio interface unit (RLRIU). The major subsystems within the computer system are the—
Central processing unit (CPU).
Input/output control unit (IOCU).
Monolithic memory unit (MMU).
Peripheral control unit (PCU).
The WCC configuration consists of two CPUs, one IOCU, and 512K of main memory.
Central processing unit.
The WCC CPU exhibits abroad variety of instructions and addressing modes as well as processing power. Each CPU has a maximum computational capability of one million ads per second (MAPS), permitting a dual central processing unit multiprocessor configuration to exhibit a two-MAPS capability.
Input/output control unit. The IOCU controls and communicates with all external interfacing subsystems. All data in the memory
is accessible by the IOCU at a one word per microsecond rate.
Monolithic memory unit. The building blocks of the WCC memory system are two monolithic memory drawers which contain
plug-in medium scale integration modules. Memory blocks of 32K may be added or removed from each drawer. Maximum
memory storage is eight blocks of 32K per drawer (256K) or 512K per system.
Peripheral control unit. The PCU is used to interconnect the hard copy unit (HCU), the recovery storage unit (RSU), the mass storage
unit (MSU), and the computer maintenance panel (CMP) with the computer.
Weapons control computer peripherals.
The WCC peripherals which are controlled by the PCU consist of the following: Hard copy unit. The HCU provides
printouts of selected tabular displays, fault detection and assessment data, and communications messages received by the FU. Printout is
initiated by the operator pressing the hardcopy key on the keyboard.
Recovery storage unit. The RSU is a highspeed dual tape drive used for loading computer programs into the WCC memory. Initialization
programs, operating programs, diagnostic programs, and data may be loaded via tape cassettes. The RSU is also used to restore the
complete contents of the computer memory in case of EMP or other electromagnetic transient which may garble or erase any portion of that
content. Following initialization, the tape in the RSU will contain a duplicate set of the program and particular site data as stored in the computer memory.
Mass storage unit. Four tape transporters and associated interface electronics comprise an MSU. The MSU is used for loading computer
programs into the WCC memory and is also used to store the operational maintenance procedures and the troop proficiency trainer
(TPT) scenarios.
Computer maintenance panel. The CMP is used for manual testing of the WCC. The switches on this panel setup, select, and control computer tests. Panel indicators show data register contents. The computer maintenance panel indicators also monitor WCC power supply, data parity, and clock functions.
