different push for 802.11ac. they see the primary beneficiary of 802.11acSingle antenna (1 stream) mobile products. By using 11ac's 80 MHz bandwidth mode, link rates of single-antenna mobile devices can be almostTripled(150 to 433 Mbps )! This will enable faster peer-to-peer wi-fi direct data transfer and higher quality screen-casting/throwing from phones and tablets to large flatscreens via wi-fi display. but again, the higher speeds will come at the expense of using wider swaths of BandwidthI

Different countries and regions have different radio management regulations (RegulatoryDomain), and there are also different rules for the division of ISM5GHz frequencies. RegulatoryDomian has three major families: the FCC represented by the United States, ETSI represented by the European Union, and TELEC, once again a maverick in Japan (both in the cellular network and WLAN, japan has always been a weird existence ). China adopts ETSI regulations. The specific frequency band management is diffe

I will upload my new book "Write CPU by myself" (not published yet). Today is 16th articles. I try to write them every Thursday. 5.2 openmips solutions to data-related problems The openmips processor uses the data push method to solve the data-related issues in the pipeline. Add some signals to the original data flow diagram in Figure 4-4 to complete data push, as shown in Figure 5-7. It mainly pushes the

As mentioned in the previous article, kernel uses 4 bitmap to save CPU core:possible, present, active, and online, respectively, in 4 states. What the meaning of these four states is. Here we will answer this question based on the relevant code logic. Before you start, take a look at the comments in the kernel: 1: * include/linux/cpumask.h * * 2: 3: 4:/*

I will upload my new book "Write CPU by myself" (not published yet). Today is 19th articles. I try to write them every Thursday. 5.6 test procedure 1-test the logical operation Implementation Effect Write the following test program to check whether the logic operation command is implemented correctly. The file name is inst_rom.s. The test program source file is available in the Code \ chapter5_2 \ asmtest \ logicinsttest directory of the attached CD

, this will be a challenge to yourself. If you solve it, it will be just the embodiment of your value. This is the same as the so-called hero in the world. All right, let's talk a little bit about it. Please visit windbg, the star of today. I will not talk about windbg any more. I only published my two points of understanding about him, which is quite popular: 1) The Memory package can be captured, that is, the dump file; 2) output the actions being

. Then, the instruction decoder generates various operation instructions based on the IR content, complete the required functions.2) PC (program counter): the CPU automatically modifies the content so that the address of the next instruction is always maintained. That is, add 1 to the PC to track the command address.3) Ar ("A" is adress) saves the address of the memory unit accessed by the current

the value of $1 in the decoding phase, at this time, 1st Ori commands are still in the execution phase. Therefore, the result is not calculated by the 1st Ori commands. If you calculate this value, errors will inevitably occur. 5-1. This situation can be called data correlation between adjacent commands. For openmips, it can also be called data correlation in the pipeline decoding and execution stages. (2
