Abstract
A programmable dedicated application card is invented comprising one or more EPROMs for storing a software application, an EEPROM storing a Host Control Program (HCP) for interfacing with a Client Interface Program (CIP) executing on a host computer system, an appropriate amount of SRAM for executing and shadowing the software application, a small amount of DRAM for use as a cache for user-data during execution of the software application, and a reduced instruction set code (RISC) processor that accesses the SRAM to execute the software application and send the results to the user via the local computer system. The PDAC is simply “plugged into” a host computer system such that when desired, the user accesses and executes the software application directly from the PDAC, thereby saving local computer resources, e.g., processor and memory, and making those resources available for other tasks. The CIP of the host computer system makes available to a user the different software applications of the local PDACs as well as the software applications available from remote PDACs.
