5.12 Processor Emulation

There are three programmable processors on the

LAVA ASIC: an ARM microprocessor, a D950 Digital

Signal Processor, and a custom DSP engine (BPU).

All these are capable of JTAG based emulation with

the following attributes:

Stop on breakpoint.

Single step

Full register R/W.

Program modification and resume.

6.0 ELECTRICAL CHARACTERISTICS
