E1-32XS
RISC/DSP Processor
A 32-Bit microcontroller design with an integrated RISC/DSP
core architecture offering maximum power efficiency in portable
multimedia and consumer electronics applications
RISC and DSP Working Together
The new E1-32XS offers a powerful RISC architecture with integrated
DSP support and 16KByte on-chip SRAM. This unique integrated
design delivers a power-efficient and cost effective solution for a wide
range of portable multimedia and consumer electronic products.
Now developers can have the best of both worlds – a fast RISC
processor for control functions, and a DSP unit for efficient algorithm
execution – yet avoid the silicon overhead and software complexity
of a dual-core design.
Integrated Core Functionality
The Hyperstone core has been specifically designed to combine both
RISC and DSP functions – but as an single integrated core and
instruction set, rather than a combination of a 2 different cores on
single piece of silicon. This fully integrated core is based on a single
processor model with a single instruction stream. Simple and efficient
communication between the RISC and DSP units is achieved via the
96-way 32-bit internal register set. A major factor in achieving the
high power-efficiency delivered by this design is the parallel opera-
tion of three functional blocks of the integrated core: the RISC ALU,
the DSP Unit and the Load/Store Unit. The integrated architecture
allows instructions to be streamed through all 3 units simultaneously
to deliver a peak performance of 720 MOPS.
Integrated RISC/DSP core with peak performance of 720 MOPS at 180MHz
Single RISC/DSP instruction stream for rapid development and
simplified debugging environment
Parallel execution of Load/Store, RISC and DSP Units
Very high code density using variable length 16, 32 and 48 bit instructions
Extremely short interrupt latency - starts code execution in less than 50 ns @180MHz
Power efficient performance of integrated core delivers peak
throughput of 3.6GOPS/Watt
Available in 16 or 32-bit external bus interface
versions, both with full internal 32-bit execution
Available as “off-the-shelf” standard LQFP
devices or as IP core for ASIC integration
Low power consumption of 200mW@180MHz at 2.5 V
using 0.25m technology
