HP 64748A Emulator for Motorola 68020/68EC020 Processors

The HP 64748A emulator supports Motorola 68020 and 68EC020 microprocessors through 33 MHz.

Real-Time Emulation

The HP 64748A is an active probe emulator that contains the microprocessor, emulation monitor, and run control circuitry. Additionally, both a custom memory mapper chip and memory are located on the probe. As a result of this technology, the HP 64748A runs up to 33 MHz with zero wait-states out of target memory.

For run control, extensive breakpoint capabilities let you define where to start and stop the execution of code. Up to 32 software breakpoints can be set up in the emulator, allowing execution to be halted at an instruction point. Hardware breakpoints increase the flexibility and power of this feature, for stopping at processor address, data and status points.

Flexible Memory Configuration

Memory modules are used for emulation memory. Two slots are available on the active probe, allowing you to plug in the amount of memory you need (up to two megabytes). If you initially order less than the maximum amount, you can easily expand your system by adding the appropriate module(s). Modules for 256 Kbyte (HP 64171A) and 1 Mbyte (HP 64171B) are available and can be sued in any combination with a maximum configuration of 2 Mbytes.

For the HP 64748A, there are zero wait-states out of emulation memory through 25 MHz operation. Above 25 MHz one wait-states is inserted.

In addition to the memory modules, four kilobytes of dual-ported emulation RAM is available when the background monitor is used. This dual-ported memory allows you to display and modify critical program variables without halting the target system.
