Part Number: TM4C1290NCZAD

Could you plrease provide me "Adjusted Peak Performance (APP)" for TM4C1290NCZAD?
Our customer need it.

Thank you and best regards,

  • Hi Yumiko-san,

      Sorry, I'm not very clear to the question on APP. Are you asking about the effective frequency when the operating frequency is 120Mhz? If this is the question then we don't have such information per se. You can fetch code or read data from either the flash or SRAM memory. The flash controller has a prefetch buffer that prefetches 256 bits (or eight 32-bit words) of instructions/data ahead of time. SRAM is single cycle access at 120Mhz. With that said, the effective frequency is very close to 120Mhz if this is the performance information you are looking. If this is not the information, then please elaborate what APP is and perhaps give me an example. 

  • Hi Charles-san,

    Sorry for the inconvenience.
    I have received the following response from CSC and submitted this to our customer.
    (Sorry for the Japanese text)

    APP 値はプロセッサ製品輸出の該非判定時に使用いただくものと考えます。左記該非判定は主に大型計
    算機を対象としAPP の規制値は29WT となっています。対して弊社プロセッサ製品(64bit の浮動小数
    点演算を行う製品)は1GHz 程度において1~4 コアの範囲で動作するIC でAPP 値は規制値(29WT)
    より2 桁以上低いものとなります。よって一律「0.01 未満」とさせて頂きます。

    I was directed by CSC to contact you, but as it turns out, CSC took care of it.
    Thank you very much for your time.

    Best regards,
    Yumiko Takaki
