The CL-PS7110 is designed for ultra-low-power
applications such as organizers/PDAs, two-way
pagers, smart phones, and hand-held internet
browsers. The device’s core-logic functionality is
built around an ARM710A microprocessor with 8
Kbytes of four-way set-associative unified cache.
At 18.432 MHz (for 3-V operation), the CL-PS7110
delivers nearly 15 Vax-MIPS of performance (based
on Dhrystone
benchmark) — roughly the same
