Nokia Siemens Networks, Inc. (hereinafter, NSN) and Motorola, Inc., a predecessor of Motorola Solutions (hereinafter, Motorola) is, NSN is 12 billion the majority of wireless network infrastructure division of Motorola announced that it has reached an agreement to acquire. In addition to greatly enhanced presence in the United States and Japan, NSN was aimed at strengthening relations with the communication business who is a customer, such as KDDI and Verizon, Motorola by this.
It had promoted the adjustment aims sale completed with December 31, the new system starting from January 1, 2011 initially, but since the approval did not get off to as "touch the Antimonopoly Law" from the China Ministry of Commerce, 12 I was postponed to the 2011 first quarter goal start to the 28th month.
January 24 next year, to federal court in Chicago, Illinois, leading telecommunications equipment vendors in China, Huawei Technologies (Huawei) is seeking the same department acquisition injunction of Motorola Solutions, which has been split from Motorola concluded by January 4 I sued Te. This was the content and intellectual property of UMTS and GSM-related with the Huawei, which has partnered with Motorola With this acquisition, such as trade secrets that over to NSN unfairly.
March 9, federal court in Chicago confirmed the appeal, acquisition story has been virtually frozen. Attention has been and whether the sale of disconnected parts acquisition itself or become re-negotiations, including other manufacturers, involved in the technology of Huawei, which has been said to be "interested there is no" and to take the NSN, but April 10 Sun Motorola settled by resolving the litigation of all was pending between the Huawei.
The division acquisition of Motorola could not be achieved at a pressure of the United States government for Huawei to one of the disputed item, accused of 2010 Huawei that had been illegally obtained confidential information of Motorola also are included from that there was also the context of, Huawei became the result of giving a considerable damage to Motorola. In response to this settlement, China Commerce Department also approved the acquisition. Completion of the sale [2], became the new system starting from April 30 concluded by April 29, 2011.
The MMU is equipped with address translation cache of 22 entry fully associative a (ATC), it has become possible to perform the address translation in parallel with the access to the data and instruction caches. Therefore, loss of time address translation by the MMU is now to be concealed, the memory access is faster if there is a conversion value to ATC.
In addition to the large improvement in these partly modified and improved parallelism of the internal processing speed is achieved as compared to the MC68020 same operation clock, reduction in power consumption due to the reduction of manufacturing processes and MMU integrated together , reduced package size, it has been realized also reduce manufacturing costs of the system by improving the bus interface.
Those requiring dozens clock multiply and divide exists the number of execution clocks of the instruction. It can be used by connecting to the coprocessor bus dedicated MC68882 is its high-speed version or MC68881, floating-point unit (FPU) is as a co-processor. It should be noted that, 68EC030 low-cost version that omits support for MMU also been released, has been a (RP suffix) inexpensive plastic pin grid array package rather than a ceramic is here.
In addition, seven of the 16 · 20 · 25 · 30 · 33 · 40 · 50MHz that there has been provided operating clock frequency for the MC68030, but, 68EC030 has become up to 40MHz, differentiation has not been achieved in the low-price version because were.
