The PA/50L is a low-cost, low-power microprocessor from Hitachi Ltd. that is fully compatible
with the PA-RISC architecture 1.1, third edition. This microprocessor achieves 55 VAX MIPS
(Dhrystone 1.1), 10.6 MFLOPS (LINPACK inner loop) and 1.3 W at 33 MHz. In order to
achieve high performance with no external cache, a non-blocking cache and a data prefetch
instruction are provided. This paper gives an overview of the microprocessor and describes
its capabilities.<>
