CHAPTER 0
• DSP Add and Subtract instructions:
signed halfword add and subtract with and without fixed-point adjustment ⇒ single
word sum and difference
• Floating-point instructions are architecturally fully integrated, they are executed as
Software instructions by the present version. Floating-point Add, Subtract, Multiply,
Divide, Compare and Compare unordered for single and double-precision, and Convert
single ⇔ double are provided.
Exceptions:
• Pointer, Privilege, Frame and Range Error, Extended Overflow, Parity Error, Interrupt
and Trace mode exception
• Watchdog function
• Error-causing instructions can be identified by backtracking, thus allowing a very
detailed error analysis
Timer:
• Two multifunctional timers
Bus Interface:
• Separate address bus of 26 (GMS30C2232) or 22 (GMS30C2216) bits and data bus of
up to 32 (GMS30C2232) or 16 bits (GMS30C2216) provide a throughput of four or
two bytes at each clock cycle
• Data bus width of 32, 16 or 8 bits, individually selectable for each external memory area.
• 8-bit, 16-bit, and 32-bit boot width selectable via two external pins.
• 5V tolerant input
• Configurable I/O pins
• Internal generation of all memory and I/O control signals
• Wait pin function for I/O accesses to peripheral devices.
• Wait pin function for memory accesses to address space MEM2.
• On-chip DRAM controller supporting Fast-Page-Mode DRAMs and EDO DRAMs.
• Up to seven vectored interrupts
• Control function for CLKOUT pin.
Power Management:
• Operating voltage : 3.3V ± 0.3V.
• Lower power supply current in power-down mode.
• Clock-Off function to further reduce power dissipation (Sleep Mode)
