0.1 GMS30C2216/32 RISC/DSP
The HME GMS30C2232 and GMS30C2216 RISC/DSP is an improved version of
HME’s existing GMS30C2132 and GMS30C2116 RISC/DSP. Using a 0.35 µm CMOS
technology, the performance of the RISC/DSP could be further improved. Being pin-
compatible to their predecessors, these new RISC/DSP can be used as a direct replacement
in existing customer’s designs.
The GMS30C2216 and GMS30C2232 RISC/DSP are based on hyperstone architecture.
Improved Points
• Maximum Operating Frequency : 108MHz @3.3V
• Operating Voltage : 3. 3V ±0.3V
• 8KByte on-chip memory
• On chip Phased Locked Loop circuit (x0.5, x1, x2, x4)
• Boot bus width selectable by two external pins
• Wait Pin Function
• On chip DRAM controller : FPM(Fast-Page-Mode), (Extended-Data-Out) EDO DRAMs.
• 5.0V Tolerant Input
• Control CLKOUT pin Function
This combination of a high-performance RISC microprocessor with an additional powerful
DSP instruction set and on-chip microcontroller functions offers a high throughput. The
speed is obtained by an optimized combination of the following features:
• Pipelined memory access allows overlapping of memory accesses with execution.
• 8KByte on-chip memory.
• On-chip instruction cache omits instruction fetch in inner loops and provides prefetch.
• Variable-length instructions of 16, 32 or 48 bits provide a large, powerful instruction set,
thereby reducing the number of instructions to be executed.
• Primarily used 16-bit instructions halve the memory bandwidth required for instruction
fetch in comparison to conventional RISC architectures with fixed-length 32-bit
instructions, yielding also even better code economy than conventional CISC
architectures.
• Orthogonal instruction set
• Most instructions execute in one cycle.
• Pipelined DSP instructions.
• Parallel execution of ALU and DSP instructions.
• Single-cycle halfword multiply-accumulate operation.
• Fast Call and Return by parameter passing via registers.
