Upwardly Code Compatible With
Existing CEVA-X Family Members, CEVA-X1641 Protects Customers' Software
Investment, Speeds Time-to-Market and Reduces Development Risk for a
Range of Applications
San Jose, CA -- CEVA, Inc. (Nasdaq: CEVA - News; LSE: CVA - News), the
leading licensor of digital signal processor (DSP) cores, multimedia and
storage platforms to the semiconductor industry, today announced the
CEVA-X1641(TM) -- the newest addition to the company's industry-proven
family of CEVA-X DSP cores and fully compliant with the CEVA-X
Instruction Set Architecture (ISA). |
CEVA-X1641 is the first
Quad-MAC DSP core in the scalable CEVA-X family and is designed
specifically to run highly computational intensive tasks that require
substantial data throughput and high memory bandwidth. The core is fully
synthesizable with enhanced memory architecture. This provides customers
with the flexibility to configure the optimal memory size and structure
for their specific application such as WiMAX, WiBro, 3G Long Term
Evolution (LTE), or advanced multimedia standards, including the
evolving H.264 compression standard and VC1 main profile. In defining
the CEVA-X1641, CEVA worked closely with a lead customer that chose to
utilize the CEVA-X-1641 for its WiMAX product line.
Like other CEVA-X ISA compliant cores, CEVA's latest DSP core is a
combined VLIW/SIMD architecture, with additional features and
enhancements required to handle the high-performance and data-throughput
requirements of 4G technologies and multimedia applications. Highly
computational intensive technologies such as WiMAX are calling for the
use of 4 MAC units, coupled with a 128bit data memory bandwidth, to
handle the extremely high data rates capable of reaching 100Mbps.
Furthermore, CEVA-X1641 incorporates specialized video instructions and
mechanisms to accelerate multimedia processing in applications like
mobile TV and video conferencing, while reducing frequency and power
consumption to extend the battery life of these fully featured mobile
multimedia devices.
"The CEVA-X1641 DSP core is in line with our strategy to offer platforms
that will support the growing need for performance and power-efficient
DSPs for emerging wireless and multimedia standards," said Gideon
Wertheizer, CEO of CEVA, Inc. "Our new, high-performance and fully
synthesizable CEVA-X1641 DSP core will enable customers to expedite
their time-to-market and reduce development costs by using the same
platform across multiple, differentiated products."
The CEVA-X1641 is upward compatible with CEVA-X1620(TM) and
CEVA-X1622(TM) DSP cores, enabling licensees of the CEVA-X1641 to
leverage the broad range of software and components already available
for the CEVA-X architecture. In addition, the CEVA-X1641 architecture is
implemented in a small size, only 5 percent larger than its Dual- MAC
predecessor, the CEVA-X1620.
Delivering on the promise of the scalable CEVA-X family introduced in
2003, the CEVA-X1641's main features are:
- 4-MAC units operating in parallel
- 8 issue VLIW
- 24 40bit accumulators
- 128bit data bandwidth
- 8/16/32/40bit data operands and
operations
- 16/32bit instructions
The VLIW architecture allows a high
level of concurrent instructions processing thus providing extended
parallelism, as well as low power consumption. SIMD architecture allows
single instructions to operate on multiple data elements that result in
code size reduction and increased performance. Low power consumption is
achieved in the CEVA-X1641 by its efficient instructions and dedicated
mechanisms such as dynamic and selective unit shutdowns and clock
gating.
The CEVA-X1641 provides a high-performance, low-power platform allowing
its licensees to develop multi-mode products (e.g., 2G/3G/4G processors)
and to reuse the same platform for next-generation standards such as
802.16e, WiBro, Flash-OFDM, UMTS and TD-SCDMA.
The CEVA-X1641, together with a complete software development tool
chain, is available for immediate licensing.
